研究大豆品种性状和所需要的肥力条件,对品种区划和确定育种目标都有重要意义.为此目的,我们以河南省1979和1980年大豆区试品种为材料,选择有代表性的试验总结进行统计分析.结果表明,品种间对土壤肥力的反应有明显差别.一材料与方法生育期95天左右的为早熟组,种植在我省北中部地区,生育期100天左右为中熟组,种植中南部地区.1979年早熟组入试品种是勤俭五号,郑74046-O-7-2、郑州126(对照)等7个品种,试验分设在西华、濮阳等十二个点.中熟组入试品种是:商丘
Studying the traits of soybean varieties and fertility requirements is of great significance for the division of varieties and the determination of breeding objectives.To this end, we take the soybean cultivars in Henan Province in 1979 and 1980 as the materials, and choose the representative test to summarize Statistical analysis.The results showed that there was a significant difference in the responses of the cultivars to soil fertility.Materials and Methods The growth period of about 95 days was the precocious group and was planted in the northern central part of our province.The maturity period was about 100 days, South-central region.The early-ripening varieties introduced in 1979 were 7 cultivars including Qinjian-5, Zheng 74046-O-7-2 and Zhengzhou 126 (control), and the test was divided into twelve spots including Xihua and Puyang. Into the test varieties are: Shangqiu
