不同国家辐射诱变大豆品种在泰国种植主要农艺性状及产量分析

The agronomic characters of radiant soybean from different countries planted in Thailand

以来自5个国家的9个辐射诱变的大豆品种为试验材料，研究不同纬度来源的大豆品种在泰国的表现。结果表明：所有参试品种的生育期在82-96d，产量为O．51-2．34t／hm^2，其中以来自泰国的Sukhothai产量为最高，来自中国的HCl8M产量为最低。构成产量的主要农艺性状的相关系数由高到低分别为每株荚数、每荚粒数、百粒重，这说明在热带地区每株荚数对产量因素的贡献为最大．每英粒数为其次．而百粒重等对产量的贡献最小。

The study was conducted between February to May of 2005 in Kamphaeng Saen Campus, Kasetsart University, Thailand. 9 radiant soybean varieties original from 5 different countries were planted in the field of ARC - AVRDC. The agronomic characteristics of these 9 varities were observed and recorded. The results shown that the maturity time of all the varieties were between 82 d to 96 d, the yield of the varieties were between 0.51 t to 2.34 t/hm^2, the variety named Sukhothai original from Thailand got the highest yield, when HC18M original from China got the lowest yield. The correlation coefficient of the yield were composed by pods per plant, seeds per pods, 100 seeds weight, from the highest to the lowest.
