Selection of Superior Lines Based on the Practical and Useful Characteristics in Korean Indigenous Soy-sprout Germplasm

摘要

The sprout characteristics for 783 sprout soybean lines screened by pure line selection method were evaluated. Those developed lines were originally collected on farmer's fields all around the country. Some of the lines showed higher yield rate of soybean sprouts of 889% and shorter root length of 2.6cm, compared with 599% and 8.7cm of Pungsannamulkong which is the most widely being cultivated as soy-sprout variety in Korea at present. The longer sprout length and shorter root length are considered as positive characters in soy-sprouts. Among the seed coat color group; yellow, green, black, brown, and mixed color, the brown showed the highest yield rate. The lines selected based on the important characteristics are as follows; KLG11183 and KLG11218for high sprout yield rate, KLG11161, KLG11178, KLG11183, KLG11187, KLG11220, and KLG11225 for sprout length, KLG11008, KLG10902, KLG11065, and KLG11996 for root length, KLG10902, KLG11008, KLG11493, and KLG11601 for rate of hypocotyl length/total sproutlength, respectively. Eighteen superior lines out of 738 tested were finally selected based on the evaluation of characteristics above mentioned as whole, which may be used for breeding materials for the development of excellent varieties for soy-sprouts.
