北京地区夏大豆品种产量构成和主要性状分析

Analysis of Yield Constitutive Factors and Main Agronomic Characters of Summer Soybean Cultivars in Beijing Area

本文对北京地区夏播大豆 9个品种 (系 )的产量构成、蛋白质、脂肪含量及主要性状进行了基本遗传参数、遗传相关分析。结果表明 ,单株产量与植株高度、主茎分枝、单株粒数遗传相关较大 ;百粒重与株高呈负相关 ;单株粒数可通过增加主茎分枝数来提高 ;

summer soybean cultivars were analyzed by the genetic parameters and genetic correlation for their constitutive factors of yield, protein and oil contents ,and main agronomic characters in Beijing area The results showed that the plant height, available branch, No of seeds per plant of soybean was high positively correlated with weight of seeds per plant of soybean No of seeds per plant was improved by select more available branch number of plant 100 grain weight was negatively correlated with plant height It is main aim to increase protein contents of summer soybean in Beijing area
