This study was performed to obtain the effective selection informations for improvement of quality and increase of yield in red pepper. The eight parents and twenty eight crosses from partial diallel were used as materials for estimation of correlations among the pericarp characters, viz, fruit length, fruit width, pericarp thickness (fresh and dry) and pericarp weight (fresh and dry), between pericarp weight and seed weight and between pericarp weight and the percent of seed weight/pericarp weight and path coefficients on fresh and dry pericarp weight. Results were as follows. In , fresh and dry pericarp weight had positive correlations with fruit length, fruit width, and pericarp thickness. Fresh pericarp weight was also positively correlated with dry pericarp weight. Dry pericarp thickness had a negative correlation with fruit length but had positive correlations with fruit width and fresh pericarp thickness. Fresh pericarp thickness had a positive correlation with fruit width. Significantly positive correlations between and mid-parents were observed in pericarp characters. Pericarp weight had a positive correlation with seed weight but had a negative correlation with the percent of seed weight/pericarp weight. In path coefficient analysis, it was found that fruit length, fruit width and pericarp thickness had direct effects on fresh and dry pericarp weight and that fruit length had the largest direct effect in .

건과육중(乾果肉重)(또는 건과육율(乾果肉率)이 상대적(相對的)으로 많은 건과용(乾果用) 고추를 육성(育成)하는데 기초자료(基礎資料)를 얻고자 8개친(個親)과 이면교배(二面交配)한 28조합(組合)을 공시(供試)하여 1건과중(乾果重)에 대(對)한 구성요소(構成要素)의 비율(此率)을 조사(調査)하고 과경중(果梗重), 태좌중(胎座重), 종자중(種子重) 및 과육중(果肉重)의 잡종강세(雜種强勢), 조합능력(組合能力) 및 유전(遺傳) 분석(分析)을 한바 얻어진 결과(結果)는 다음과 같다. 친(親)과 에 있어서 1건과중(乾果重)과 구성요소(構成要素)들은 초기과(初期果)가 중기과(中期果)에서 보다 모두 무거웠다. 그리고 초(初), 중기과(中期果)에 있어서 이들은 모두 친간(親間), 간(間)에 1%의 유의(有意)를 나타내었고, 이 친(親)보다 무거웠으나 초기과(初期果)의 친(親)은 중기과(中期果)의 보다 무거웠다. 1건과중(乾果重)에 대(對)한 구성요소(構成要素)들의 비율(比率)은 과육(果肉)이 가장 높고 다음은 종자(種子)였다. 과육율(果肉率)은 초기과(初期果)보다 중기과(中期果)에서 다소(多少) 증가(增加)되었고 종자율(種子率)은 상대적(相對的)으로 감소(減少)되었으며 과경(果梗)과 태좌(胎座)는 수확시기(收穫時期)에 따른 차이(差異)가 없었다. 무거운 친(親)을 초월(超越)하는 조합(組合)이 상당(相當)히 있었으며 평균(平均)heterosis(%)는 모두 정(正)의 값을 나타내었고 평균(平均)heterosis(%)는 종자(種子)와 1건과중(乾果重) 외(外)는 모두 부식(負植)를 나타내었다. GCA는 SCA는 모두 1%의 유의성(有意性)을 나타내었으며 GCA가 SCA보다 컸다. 무거운 쪽이 모두 우성(優性)을 나타내었고 과경(果梗)은 부분우성(部分優性), 태좌(胎座), 과육(果肉) 및 1건과중(乾果重)은 완전우성(完全優性), 종자(種子)는 초우성(超優性)을 타나내었다. 유효유전자수(有效遺傳子數)는 과경(果梗)과 태좌(胎座)는 1개(個), 종자과육(種子果肉) 1건과중(乾果重)은 2개(個)로 추정(推定)되었으며 유전력(遺傳力)은 모두 높았다. This study was performed to obtain the basic informations for red dry pepper fruit with more pericarp weight(or in percentage) with a complete diallel cross(excluding reciprocals) using eight cultivars. Heterosis, combining ability and inheritance of the dry red fruit weight and its components(stem, placenta, seed, and pericarp) were evaluated. The results obtained were summarized as follows : Dry weight/fruit and its four antomical components were heavier in the earlier harvest fruit than in that of the later fruit. They showed 1% significance among parents and , and those of were significantly heavier than in parent. All characters in earlier fruit of parent, however, were higher than in later fruit of . Dry weight percentage of pericarp to dry weight/fruit was highest followed by seed. Percentage of pericarp in the later fruit was increased while the seed decreased and percentages of stem and placenta were not differed between the earlier and later fruit. hybrids above the higher parent were observed in all characters. Mean heterosis (%) was positive in all characters while mean heterobeltiosis (%) was negative excepting seed and dry weight/fruit. GCA and SCA variances were highly significant, and GCA vaiances were greater than SCA in all characters. The directions of dominance were positive. Partial dominance was shown in stem, complete dominance in placenta, pericarp and dry weight/fruit, and over dominance in seed. The effective genes were estimated as one for stem and placenta, and two for seed, pericarp and dry weight/fruit. Heritabilities in narrow and broad sense were higher.

In order to know the component ratio to fruit weight in F1 hybrids of red pepper, the weight of (1) penduncle and calyx, (2) pericarp, (3) seed, and (4) plancenta and interlocular septum was weighed and compared with their parents (Table 1-5). And correlation coefficients between components and their regression equation were calculated (Table 6). In general, the weight of each component in F1 hybrids were between parents and there were shown the higher positive corelations between them.

This studies were made to know the extent of apperaance of necrosis in radish seeds exposed to dry heat (100℃) and that in what parts of the seeds, the necrosis occures firstly, and discussed in conpaison with the seeds of Chinese Cabbage. The frequency of appearance of partial necrosis were higher in cotyledon but that of "all necrosis" were more in radicle. In the parts of cotyledons and radicles, the lateral part and upper had higher frequncy than other, respectively.

The objective of this investigation was to obtain the necessary information for the increment of the cultivated land utilization and the establishment of more reasonable multiple cropping system in paddy and upland around Kyungpook Province. For the analysis of the obtained data we used the fixed model employing the arbitrary classification of the regions in sampling. The results of this investigation were summarized as follows: 1. In the acreage per farm household, it was obvious that the farm household in the suburban and truck farming regions has more upland acreage than paddy. On the contrary, there was the exactly reverse trend in the intermediate and fall-behind regions. 2. The old Japonica rice varieties were utilized in the suburban and truck farming regions comparing with the intermediate and fall-behind region using the new Indica-Japonica rice varieties. This tendency in the suburban and truck farming regions was closely associated with the cultivation, especially the harvesting date, of the post-crop after rice. Therefore, it was highly recommandable to develop new high yielding rice variety for the late transplanting in these regions. 3. The rate of the paddy utilization was the highest in the suburban region and was very low in the intermediate and fall-behind region. On the whole regions, the larger paddy owner utilized the lesser in its rate. 4. Barley was cultivated most widely as post-corp after rice in the sampling area. Vegetables in the suburban regions and water melon in Seongju and garlic in the Euiseong were main post-crops in the paddy multiple cropping systems. 5. The rate of the upland utilization was the highest in the suburban regions and was very low in the truck farming region because red pepper and tobacco production region employing only one crop per year. 6. In the double cropping system on the upland, barley and soybean combination was most in the cultivated acreage. The main double cropping system available in the suburban region was fruit vegetables and Chinese cabbage combination. 7. For the increment of the paddy and upland utilization, and of the farm income through the establishment of the reasonable cropping system, it will be desirable to study various possible multiple cropping systems on the experimental basis and the introduction of new crops and varieties may be considered for the incentive of production and return.
