The correlation among days to germination, days to flower, days to seed ripening and number of seeds per a pod and their combining were studied in 15 F₁s from the partial six-parent diallel cross in Petunia hybrida. The days to flowering, days to germination and seed number per a pod showed high positive correlation together, however germination percentage and number of seed showed negative correlation with days to ability(SCA) were highly significant for all the characters. The estimates of variance components of SCA were greater than those of GCA for all the characters, showing preponderance of non-additive gene actions for these characters. The line of A and C showed relatively high GCA effect for days to germination and days to flower and the lines of C and G for germination, days to seed ripening and number of seeds per a pod. The crosses of D×G and E×F exhibited high SCA effect for decreasing days to flower and days to germination, and increasing germination percentage and number of seeds per a pod. The broad sense heritability was generally high compared to narrow sense one in the 5 characters. The higher heritability values of both broad and narrow sense were shown in the days to ripening and number of seeds per a pod.

The inter-relationship and combining abilities of characters for leaf length, leaf width, branch number, leaf number, leaf area, fresh weight and dry weight were studied in the F₁ combination of 15 crosses from the partial six-parent diallel cross in Petunia hybrida. The leaf area, fresh weight and dry weight showed high positive correlation together with the other growth characters such as leaf length, leaf width, branch number, leaf number. The mean squares of general combining ability(GCA) and specific combining ability(SCA) were highly significant for all the growth characters. The estimates of variance components of SCA were greater than those of GCA for all the characters, showing preponderance of non-additive gene actions for these characters. GCA effect was high in the lines of D and G for leaf length and fresh weight, and in the lines of C and D for branch number, leaf number, leaf area and fresh weight. The crosses of D×E, D×G, and E×G exhibited high SCA effect for all the growth characters such as leaf length, leaf width, branch number, leaf number, leaf area, fresh weight, and dry weight. The broad sense heritability was generally high compared to narrow sense one in the 7 characters. The highest heritability of the broad and narrow sense was shown in the leaf width and dry weight.

This study was conducted to determine correlations and combining abilities of leaf lengths, leaf widths, petiole lengths, number of branches, number of leaves, leaf areas, fresh weights, dry weights and number of flowers in F₁ crosses made with the partial seven-parent diallel cross in Viola tricolor. Leaf lengths and leaf widths showed highly positive correlation with petiole length and negative correlation with number of branches, number of leaves and number of flowers. There was positive correlation between the number of leaves and flowers as well as between leaf area and fresh weight. Mean squares of general combining ability(GCA) and specific combining ability(SCA) were highly significant for all the parameters. Variance component values of SCA were greater than those of GCA for all the parameters except leaf length, implying preponderance of non-additive gene actions for these characters. The lines C and G for leaf lengths and widths, the lines A and F for number of leaves, the lines A, B and G for leaf areas, and the lines B and F for number of flowers showed relatively high GCA effects. The crosses of A×B and B×D exhibited high SCA effects on increasing leaf lengths, leaf widths, number of leaves, fresh weights and number of flowers. And also the crosses of B×E and D×G exhibited high SCA effects on decreasing leaf lengths, leaf areas and fresh weights as well as increasing number of flowers. The broad sense heritabilities of most characters were high compared with the narrow sense one. Those of leaf length, leaf width, petiole length and number of leaves were high in both the broad and narrow sense heritabilities.

송천영,박병모,문자영,Song, C.Y.,Park, B.M.,Moon, J.Y. 국립한국농수산대학교 교육개발센터 2018 현장농업연구지 = Journal of practical agricultural resear Vol.20 No.2

There is a need to breed and distribute domestic varieties for Lilium Asiatic hybrids because most of the lily bulbs cultivated in Korea imported from foreign country. The genetic resources of Lilium Asiatic hybrids, 'Buff Pixie', 'Orange Matrix' and 'Tiny Puppet', which were collected from 2001, had been self-pollinated from 2004 to 2012. In 2012, Lilium Asiatic 'Lovely LiASong' as an F₁ hybrid was bred through crossing 'L₂-12-1' and 'L₂-35-4' obtained by 4th self-fertilization. 'Lovely LiASong' had a bowl shaped single flower with a few spots and medium-sized flower, 8.7cm in flower diameter. The number of flowers per plant was 4.9, which was relatively more flowers than other cultivars. And the flower inflorescence had umbellate and racemose while the attitude of longitudinal axis was erect. The plant height was 33.4cm with 30.4 leaves per plant and 7.2cm in leaf length. The 'Lovely LiASong' showed a high consumer preference because it had a relatively longer flowering period, larger flower diameter and number of flowers than those of the control, 'Tiny Ghost'.

This study aimed to select the media for water flooding culture of Pinus thunbergii Parl., Juniperus chinensis L. var. sargentii Henry, Osmanthus fragrans Lour., and Chaenomeles japonica Lindl. ex Spach planting into quartz Porphyry and Hydroball. The survival rate of Pinus thunbergii Parl. and Chaenomeles japonica Lindl. ex Spach in hydroball 80%+quartz porphyry 20% was 100%, also the ratio of Juniperus chinensis L. var. sargentii Henry and Osmanthus fragrans Lour. in hydroball 20%+quartz porphyry 80% was 100% and 80%. However survival rate of full water and decomposed granite was less than 80% in Pinus thunbergii Parl., Juniperus chinensis L. var. sargentii Henry, and Chaenomeles japonica Lindl. ex Spach and thee rate of Osmanthus fragrans Lour was less than 50%. The increasing rate of fresh weight for Pinus thunbergii Parl. and Chaenomeles japonica Lindl. ex Spach in hydroball 80%+quartz porphyry 20% was 58.6% and 15.8% which was higher than others, and the fresh weight was increased as increasing the content of hydrobol. However the fresh weight of Juniperus chinensis L. var. sargentii Henry and Osmanthus fragrans Lour. in hydroball 20%+quartz porphyry 80% was 71.4% and 59.7% which was higher than others, and the fresh weight was increased as increasing the content of quartz porphyry. The increasing rate of fresh weight of decomposed granite as control was the lowest by 32.7%, 48.0%, 33.3% and 7.0%, respectively in Pinus thunbergii Parl., Juniperus chinensis L. var. sargentii Henry, Osmanthus fragrans Lour., and Chaenomeles japonica Lindl. ex Spach. Therefore the survival rate and fresh weight was lower at water and decomposed granite. However the survival rate and increasing fresh weight of Pinus thunbergii Parl. and Chaenomeles japonica Lindl. ex Spach was higher as increasing the rate of hydrobol. And the survival rate and fresh weight of Juniperus chinensis L. var. sargentii Henry and Osmanthus fragrans Lour was higher as increasing the rate of quartz porphyry.

우리나라에서 재배되고 있는 백합 구근의 대부분을 수입에 의존하고 있어 국내 품종을 개발하여 보급할 필요가 있다. 분화용 나팔나리 유전자원 'Ace', 'Nelli White'를 수집하여 1996년부터 2010년까지 자가수정을 실시하였다. 2012년에 자가수정 7세대 'L₂-17-4' 과 'L₂-16-6' 계통을 교잡하여 1대잡종 나팔나리 'Bright LoSong'를 개발하였다. 'Bright LoSong'은 균일성 및 지역성응성 검정은 바탕으로 2014년부터 2015년까지의 품평회를 통하여 선발하여 품종 등록은 2017년에 되였다. 분화용 나팔나리 일대잡종 'Bright LoSong'는 백색의 나팔모양의 홑꽃으로 반점이 없으며, 식물체 당 개화수가 5.8개로 많은 편이며, 꽃의 직경은 9.8cm이고 측향으로 개화한다. 초장은 38.4cm이고, 잎의 수는 30.8개이고, 잎의 길이는 14.9cm이며, 잎의 폭은 1.9cm이다. 일대잡종 'Bright LoSong'는 대조품종인 'Mount Carmel' 보다 화수가 많아서 개화 기간이 길며 소비자 선호도가 높다. 일대 잡종 'Bright LoSong'은 실내에서 재배가 원활하여 분화용으로 선호도가 우수하며 양친을 순계화하여 육성하였기 때문에 품종의 재현이 가능하다. There is a need to breed and distribute of domestic varieties for Lilium longiflorum because most of the lily bulbs cultivated in Korea were imported from foreign country. The L. longiflorum 'Ace' and 'Nellie White' collected from 1996 had been self-crossed from 1996 to 2010. In 2012, the L. longiflorum 'Bright LoSong' was developed as a F₁ hybrid crossed between 'L₂-17-4' and 'L₂-16-6' that obtained by 7th self-fertilization. The 'Bright LoSong' was tested for homogeneity, regional adaptability test, consumer preference show from 2014 to 2015, and it was registered in 2017. The flower of 'Bright LoSong' is a trumpet shaped single flower with no spots.It has 5.8 flowers per plant, which is a relatively many number compared control 'Mount Carmel', Its flower diamater is 9.8cm, relatively a bit small size. And the flower inflorescence has umbel or raceme while the attitude of longitudinal axis is horizontal. The plant height is 38.4cm with 30.8 leaves per plant and 1.9cm of the leaf width. 'Bright LoSong' has a longer flowering period because of relatively small diameter or many number of flowers than those of the control 'Mount Carmel'. Thus, the 'Bright LoSong' showed a high consumer preference, and the cultivar has the advantage of being able to reproduce since the parents are pure lines.

Jr.) Backbg, Notocactus scopa (Spreng.) Berg., Lobivia nealeana Backbg., Mammillaria elongata var. intertexta (DC.) SD., Pseudoespostoa (Vp1.) Backbg., Mammillaria albilanata Backbg., Mammillaria klissingiana Bod. and Espostoa lanata (HBK.) Br. & R. The main 10 succulents are Kalanchoe thyrsifolia Harv., Portulacaria afra var. foliis-variegatis Jacobs., Crassula perforata Thunbg., Echeveria pulvinata Rose, Aeonium arboreum cv. atropurpureum., Echeveria lauii Moran & J. Meyran, Pachypodium lamerei Drake, Sedum rubrotinctum cv. Aurora Boom., Aloe mitriformis Mill., and Euphorbia coerulescens Haw. The cacti were native to Mexico, Brazil, Peru, Paraguay, Ecuador, etc. The sucullents were native to Mexico, Africa, Gran Canaria, Madagascar, etc. Most of all the cacti and sucullents in the experiment are growing well under full sun or light shade, however Portulacaria afra var. foliis-variegatis Jacobs, and Sedum rubrotinctum cv. Aurora Boom. did not influenced by light. And all the plants require a little or moderate watering. Thus, planting by similar required water and light, when growing in a pot of several cacti and succulents, might be decreased the rate of death causing by their different plant physiology.

몇 가지 도자기 분 식물의 계절별 식재시기가 생육에 미치는 영향

송천영,문자영,김리나,Song, C.Y.,Moon, J.Y.,Kim, L.N. 국립한국농수산대학교 교육개발센터 2018 현장농업연구지 = Journal of practical agricultural resear Vol.20 No.1

도자기 분 식물 식재시기가 식물의 생장에 미치는 영향을 알아보기 위하여 청미니호랑가시나무(Ilex cornuta Lindl.), 무늬호랑가시나무(Ilex aquifolium 'Silver Queen'), 무늬산호수(Ardisia pusilla 'Variegata') 및 철쭉(Rhododendron indicum(Satsuki azalea))을 2017년 4월 1일부터 12월 1일까지 6차례(4월 1일, 6월 1일, 7월1일, 8월 1일, 10월 1일, 12월 1일) 식재하여 12주간 생존율 및 생육을 조사하였다. 식재 시기에 따른 생존율에서 청미니 호랑가시나무는 4월, 10월, 12월 식재 시 100%이였으나 6월 식재는 90%, 7월 식재는 50%, 8월 식재는 60%를 보였다. 무늬호랑가시나무 및 철쭉의 생존율도 7월과 8월이 낮은 경향이고 그 외시기는 100%로 조사되었다. 하지만 무늬산호수는 모든 식재 시기에서 100%의 생존율을 보였다. 식재시기별 청미니 호랑가시나무의 초장 생장율은 6월, 7월 및 8월 식재에서 20.0%, 15.5% 및 16.5%이었으나 4월, 10월 및 12월 식재는 13.2%, 12.3% 및 10.7%로 낮았다. 엽수 및 초폭의 증가율도 6월부터 8월 한여름의 식재는 높게 나타났으나 4월, 10월 12월은 낮았다. 무늬호랑가시, 무늬산호수 및 철쭉의 식재시기에 따른 식물생장도 한여름에는 촉진되고 봄과 가을에는 정상적인 생장을 보였다. 따라서 도자기 분화를 계절별로 식재 했을 때, 7월과 8월 한여름의 식재는 식물 생장은 촉진되지만 생존율이 낮아지는 문제가 있으므로 한여름의 식재는 피하는 것이 바람직하다고 결론을 내릴 수 있다.
