大豆曲茎材料PI227224在南京分期播种及杂交试验的结果表明：曲茎性状受不同播期的光温条件影响，夏播下曲茎表现程度高于春秋播；曲茎与矮秆各受一对隐性基因控制，曲茎和矮秆之间存在连锁关系，用极大似然法估算的重组值r为9．23±1．22％。
Soybean stalk material PI227224 in Nanjing sowing and hybridization test results show that: Stalk traits by different sowing light and temperature conditions, the summer sowing curved stems higher than the performance of spring and autumn; curved stems and dwarf by a pair of There was a linkage between recessive gene control, curved stem and dwarf. The recombination value r estimated by maximum likelihood method was 9.23 ± 1.22%.
