Effects of Ratio between Parental Lines and Spacing on Seed Yield of Hybrid Soybean in Taonan
摘要
Abstract
A field experiment was conducted to investigate the best parents planting configuration on seed production of hybrid soybean. The experiment was conducted with two levels of row spacing(45 and 65 cm) each at four levels of male to female row ratio( 1: 1,1: 2,1: 3 and 1:4) in 2011 and 2012 in Taonan area, Jilin province, with JLCMS34A and JLR11 as female and male parent, respectively. Hybrid seed yield in 45 cm row space was higher than 65 cm. Seed yield increased with the increasing of female parent rows. Highest yield of 1 396. 7 kg·ha-1 was obtained under 45 cm row spaces and parents row rates of 1: 4, increased by 35% compared with the traditional planting pattern of 65 cm row spaces and parents row rates of 1: 2. Results suggest that reducing row space and increasing female parent row ratio could decrease pods and seeds per plant, enhance 100-seed weight,and hence increase seed yield.关键词
