【摘要】 选用 12个矮秆紧凑玉米自交系与四川省内常用的 7个自交系按 12× 7不完全双列杂交设计。结果表明 :d15 1、d15 5、15 6 1、d392、P138的产量一般配合力高 ,而株高的一般配合力较低 ,以它们为亲本 ,有望组配出矮秆大穗的新组合更多还原

【Abstract】 Twelve maize inbred lines with short stalk and erect leaf and seven others often used in Sichuan were adapted to analyse the combining ability of maize through 12×7 incomplete diallel cross. The results showed that GCA of yield of d151,d155,156 1,d392, P138 were higher,but GCA of their plant height were lower. So new combinations with short stem and big spike will be developed by selection.更多还原
