Effects of leaf shape on seed yield and its components in soybeans

摘要

An obvious feature of soybean cultivars in southern China was less number of seeds per pod (NSPP). Soybean breeders believed that NSPP was related with leaflet shape, in other words, narrow leaflet type usually provided more NSPP. A greater number ofcultivars in Northeast China and Huang-Hui-Hai Valleys were narrow leaflet type. But, so far, narrow leaflet trait has not been recognized and emphasized in the improvement of soybean yield in southern China. This paper deals with the effects and significance of leaf shape in the improvement of seed yield and NSPP in Nanjing, China.
