야생콩과 재배콩 교잡 계통의 조사료 수량 및 품질 평가

국문 초록 (Abstract)

본 연구는 야생콩과 재배콩의 교잡 후대 집단에서 25계통을 선발하여 사료 수량 및 품질을 평가하여 사료용 콩 품종육성 가능성을 검토하였으며, 그 결과를 요약하면 다음과 같다. 먼저, 야생콩과 재배콩 교잡종의 조사료 수확시기별 수량 및 품질 검정에서 교잡종을 대조품종인 재배콩과 비교하여 보았을 때 사료의 수량이나 품질을 고려하면 협비대기인 R6에 가장 우수한 것으로 평가가 되었다.야생콩과 재배콩의 교잡후대 계통에 대한 사료 수량 및 품질평가에서 대조품종과 비슷하거나 유의적인 차이가 없는 수량이 높은 계통을 선발할 수 있었으며, 가식부위 생체중은 대조품종인 재배콩 보다 교잡종이 상대적으로 높은 것으로 평가가 되었다. 교잡종에 대한 사료품질을 평가한 결과 AFGC의 두과 건초 품질 등급기준에 따라 나누었을 때, 특등급의 조건인 조단백질 함량 19% 이상, NDF 함량 40% 미만, ADF 함량 31% 미만, DDM 65% 이상, DMI 3.0% 이상, RFV 151 이상을 모두 충족시키는 계통을 선발할 수 있었고, 이들중 몇몇 계통은 수량도 우수한 것으로 평가가 되었다. 따라서, 재배콩과 야생콩의 교잡을 통해 사료 수량 및 품질이 우수한 사료용 콩을 개발할 수 있을 것으로 판단된다.

This study was conducted to evaluate forage yield and quality for the accessions derived from inter-specific cross between wild and cultivated soybeans. First of all, three soybean lines (W02, W09 and W11) derived from PI483463 (Glycine soja) x Hutcheson (G. max) and three cultivated soybeans (Daewon, Pungsannamul and Bosug) were evaluated to determine forage yield and quality at the R2 (full bloom stage), R4 (full pod stage) and R6 (full seed stage) stages of development. Based on forage yield and quality, R6 was determined the optimal harvest stage to provide forage of high quality and adequate quantity for animals in both lines derived from G. soja x G. max and cultivated soybean. Second, 25 selected lines from PI483463 x Hutcheson or S-100 (G. max) x PI483463 and four common seed-type cultivars (Bosug, Pungsannamul, Taekwang and Hutcheson) were evaluated to determine forage yield and quality at stage R6 in 2010. Hutcheson had the highest forage yield with 24.7 t/ha in fresh weight (FW) and 6.6 t/ha in dry matter (DM) among cultivated grain soybeans. A selected line W11 had highest FW (25.7 t/ha) and DM (6.2 t/ha) among G. max x G. soja selections. Five selected lines (W02, W06, W11, W13 and W18) had similar forage yield compared to Hutcheson. Generally the 25 selected lines derived from G. soja x G. max had thinner main stems and branches which lead to get more edible forage than cultivated soybeans. When selected lines were evaluated for their feed quality as per forage grade by American Forage and Grassland Council, 23 lines had a crude protein with more than 19%; 9 lines had a neutral detergent fiber below 40%; 23 lines had an acid detergent fiber below 31%; 24 lines had a digestible dry matter of more than 65%; 13 lines had a dry matter intake of more than 3.0%, and 17 lines had an relative feed value higher than 151 or were equivalent to prime grade. And all of 25 inbred lines were equivalent to Grade 1. Therefore, inter-specific cross between G. max and G. soja will be an excellent way to develop forage soybean with good yield and quality.
