| Abstract: | Objective] The purpose was to analyze the agronomic characters and quality of bred summer soybean varieties in Hebei Province.Method] The agronomic characters and quality characters of 40 summer soybean varieties in Hebei Province authorized since 1975 were analyzed.Result] The yield of summer soybean was increased from 2 250 kg/hm2 in 1975 to 2 940 kg/hm2 in 2007,with 30% of yield increase.Their agronomic characters of them were follows: plant height of 70-100 cm,growing days of 90-105 d,branches of more than one,purple flower,round leaf,growth habit of sub-determinate or determinate.The tested cultivars that had round seed,yellow or brown hilum and the hundred seeds of over 18 g accorded for 10% of the total.There were 4 cultivars that had protein content above or equal to 44%,being 10% of the total.22 cultivars had the protein content from 41% to 44%,being 55% of the total.9 cultivars had the fat content above or equal to 21%,being 22.5% of the total.25 cultivars had the fat content from 18% to 21%,being 55% of the total.6 cultivars had the content of protein and fat above or equal to 63% and fat content above or equal to 20%,being 15% of the total.Conclusion] This study provided reference base for introduction and breeding of summer soybean. |
