To obtain the basic informations for the mutation breeding and to select the morphological mutants in peanut (Arachis hypogaea L.), the seeds were treated with gamma rays of 0-30kR, and the induction frequency of mutation in M₂ generation and distribution of morphological mutants in M₃ generation. The morphological characteristics induced by gamma-ray in M₂ generation were the short stem, few branches, leaf shape, multipods and botanical type. The induction rate of mutation was 16.0% at 30kR in cotyledonary branch. Distribution of mutants of short stem length, few branches multipods selected in M₂ generation were 31%, 35%, 23%, respectively. In M₃ generation, the main stem length and number of pods per plant were negative correlation with the yields in the short stem mutants lines and the number of branch and pod per plant were highly positive correlation with the yields in few branches mutants lines and the number of pods per plant was highly positive correlation with the yields in multipoded mutants lines.

In order to obtain the basic information on the mutation breeding in peanut and to find out the efficient methods for the induction of mutation and selection criteria, the seeds of peanuts were subjected to mutagen treatment with the various levels of the γ-ray dosages (10, 20, 30 and 40kR) in the seeds contained different moisture. Emergence and survival rate of M₁ plants were decreased by the increase of dosage of gamma rays and the lethal dose (LD₅₀) was 30-40kR in the dried peanut seeds. The higher radiation dose level and moisture content in seeds lead to the more radiosensitivity in M₁ generation. The lethal dose (LD₅₀) of peanut seed with 10-25% moisture content was around 20kR. The order and spectra of chlorophyll deficient mutations were maculata, chlorotica, chlorina, albina and the total chlorophyll-deficiency rate was 14.8% at 30kR dose in the cotyledonary branch. The chlorophyll deficieny rate was negatively correlated with the main stem length and number of pods per plant in M₁ generation. The highly positive correlation coefficients between chlorophyll deficieny rate and morphological variant rate was observed in M₂ population

This study aimed to determine the optimal harvesting time for wheat to make grain silage, in Honam region of Korea. We harvested wheat grain every third day from 30 to 42 days after heading (DAH). The moisture content decreased from 61.6% at 30 DAH to 42.8% at 42 DAH. Yield of wheat grain significantly increased from 30 to 42 DAH (p< 0.05). Yield at 39 DAH (3.46T/ha) was not significantly different from that at 42 DAH (p< 0.05). With respect to the feed value of wheat grain silage, the amount of crude protein, crude fiber, and crude ash was different by harvesting time (p< 0.05). However, the amount of total digestible nutrients (TDN) from 30 and 42 DAH was not significantly different. The pH of wheat grain silage from 30 to 42 DAH was between 3.8 and 4.5 and it was stable until 39 DAH (p< 0.05). The lactic acid content of wheat grain silage from 30 to 42 DAH decreased from 3.08% to 1.10%. With respect to moisture content, yield, feed value, and fermentation, the optimal harvesting time for wheat grain silage was 39 DAH. 출수 후 수확일수에 따라 수량 및 사료가치를 고려해 보면 밀 수량은 출수 후 30일부터 42일까지 유의적으로 증가하였으며(p<0.05), 최대 수량은 42일차에 5.57T/ha이었는데, 39일, 42일차와는 유의적 차이를 보이지 않았다. 사료가치의 경우 조단백, 조섬유, 조회분의 경우 유의적 차이를 보이나, 조지방, TDN의 경우 유의적 차이를 보이지 않았다(p<0.05). 발효에 영향을 주는 pH는 30일부터 39일까지는 pH 3.8-4.2까지 안정을 유지하다가 42일차부터는 pH4.5로 증가하여 일부 품종의 경우 발효에 적합하지 않았다(p<0.05). 따라서 밀의 곡실 발효사료 제조를 위한 최적 수확시기는 출수 후 39일차였다.

송태화,강천식,정영근,박종호,박태일,Song, Tae-Hwa,Kang, Chon-Sik,Cheong, Young-Keun,Park, Jong-Ho,Park, Tae-Il 한국초지조사료학회 2017 한국초지조사료학회지 Vol.37 No.4

이 연구는 배합사료 대체용 분쇄사일리지를 조제하기 위한 보리와 밀의 적정 수확시기와 사료가치 및 발효품질을 구명하고자 실시하였다. 그 결과, 수분함량은 새쌀보리와 금강밀 모두 수확시기가 늦어짐에 따라 감소하는 경향을 보였는데, 수분감소는 새쌀보리가 금강밀보다 더 빠르게 진행되었다. 생육특성에서 수확시기에 따른 초장길이의 변화는 없었고, 경수는 감소하는 경향을 보였다. 건물수량과 TDN수량은 새쌀보리는 출수 후 35일과 40일에서 출수 후 30일보다 유의적으로 높은 값을 보였고, 금강밀은 출수 후 40일과 45일에서 출수 후 35일보다 유의적으로 높은 값을 보였다(p<0.05). 조단백질 함량은 수확시기가 늦어질수록 새쌀보리와 금강밀 모두 증가하는 경향을 보였고, 조섬유, 조지방 및 조회분함량은 수확시기가 늦어짐에 따라 비슷하거나 약간 낮아지는 경향을 보였으나 통계적인 유의성은 없었다. NDF와 ADF 함량은 수확시기가 늦어짐에 따라 새쌀보리는 감소하는 경향을 보였고, 금강밀은 비슷한 경향을 보였으며, TDN 함량은 수확시기에 따라 새쌀보리는 다소 증가하는 경향을 보였으나, 금강밀은 비슷한 값을 나타냈다. 총체분쇄 사일리지의 발효 전 후 사료가치는 일반성분들이 약간 증가되는 경향이 있었지만 통계적인 유의성은 없었다. 발효품질면에서 수확시기가 늦어짐에 따라 새쌀보리는 pH가 높아지고 젖산함량이 유의적으로 낮아졌으며(p<0.05), 금강밀은 pH가 비슷한 값을 보였고, 젖산함량은 낮아지는 경향을 나타냈다. 따라서 총체분쇄 사일리지를 조제하기 위한 적정 수확시기는 수량성과 품질을 같이 고려해보면 새쌀보리는 출수 후 35일이 적절하고, 금강밀은 출수 후 40~45일이 적절할 것으로 사료된다. This study was carried out to investigate the optimal harvesting time, feed value and fermentation quality of barley and wheat for the making of chopped whole crop silage substitute for formula feed. As a result, the moisture content of barley and wheat decreased with a late harvest, and barley progressed faster than wheat. The plant height was similar with harvesting time, and the number of spikes decreased with prolonged period after heading. The dry matter yield and TDN yield of barley harvested at 35 and 40 days after heading were significantly higher than those at 30 days after heading and wheat was significantly higher at 40 and 45 days than at 35 day after heading(p<0.05). Crude protein content of barley and wheat were increased with later harvesting time, and crude fiber, crude fat and crude ash were slightly decreased, but not statistically significant. NDF and ADF content of barley decreased with later harvesting time, and those showed similar level in wheat. TDN content of barely was slightly increased but there was no difference in wheat. Comparing the effects of fermentation on feed value of chopped whole crop silage, the approximate compositions were slightly increased after fermentation, but the difference was not significant. Fermentations resulted in increasing the pH value of barley silage with late harvesting time, but decreasing the lactic acid content(p<0.05). A pH value of wheat silage showed similar level in different harvest time, and lactic acid content was decreased. Considering the quantity and quality of fermentation, barley and wheat can be used for making chopped silage of whole crop silage when they were harvested at 35 days and 40~45 days after heading, respectively.

This experiment was conducted to obtain information of feed value and fermentative quality of wheat cultivar, 'Taejoong' to confirm availability as a whole crop silage. As a result, the heading date of 'Teajoong' is April 27, and plant height is longer than whole crop barley, 'Youngyang' or whole crop wheat, 'Cheongwoo', spike length are also large, fresh and dry matter yield are also high. In case of feed value, 'Taejoong' had higher crude protein content than whole crop barley, 'Youngyang' or whole crop wheat, 'Cheongwoo', lower NDF and ADF contents, and significantly higher digestible nutrient contents(p<0.05). In case of fermentation qulity, pH of 'Taejoong' was 4.2, and lactic acid content was lower than 'Cheongwoo' silage and significantly higher than 'Youngyang' silage(p<0.05). Acetic acid content was significantly lower than 'Youngyang' and 'Cheongwoo' silage(p<0.01), butyric acid content was significantly lower than that of 'Youngyang' silage (p<0.05). The final Flieg's score showed that 'Taejoong' silage was the best. Also income of 'Taejoong' improved than 'Youngyang' or 'Cheongwoo'. Therefore, 'Taejoong' is considered sufficiently available as whole crop for forage.
