应用植物生长分析、生物化学分析和 Ｒ Ａ Ｐ Ｄ 技术，对１９９０ 年从吉林省引进，已在杭州分别种植１ 季、６ 季和８ 季的４ 个大豆品种吉林２０ 号、吉林２１ 号、吉林２３ 号、吉林２５ 号进行农艺性状、经济性状和基因组 Ｄ Ｎ Ａ 的比较研究。结果表明：各品种在杭州种植６ 季以后，株高增加，百粒重增加，总粒数减少，每荚粒数不变，分枝数减少，蛋白质含量升高，基因组 Ｄ Ｎ Ａ 未见显著变化。吉林２３ 号在杭州的适应性较好。
Using plant growth analysis, bio-chemical analysis and RAPP technology, four soybean cultivars, Jilin 20, Jilin 21 and Jilin 21, which were introduced from Jilin Province in 1990 and grown in Hangzhou in the first, the sixth and the eighth seasons respectively, 23, Jilin 25 for comparative analysis of agronomic traits, economic traits and genomic D N A. The results showed that after six seasons were planted in Hangzhou, the plant height increased, the grain weight increased, the total grain number decreased, the number of pods per grain remained unchanged, the number of branches decreased and the protein content increased. Variety. Jilin 23 in Hangzhou better adaptability.
