摘要
12个甜玉米自交系以不完全双列杂交配成36个组合,分析其7个主要穗部性状的一般配合力(GCA)、特殊配合力(SCA)及遗传参数。结果表明,各性状一般配合力表现出比特殊配合力更大的遗传变异,筛选出6个优良自交系0583、05135、05148、0569、05101和05132及8个优良组合:05148×0581、0572×05132、0574×0569、0572×0569、0572×05133、0583×05133、05130×05101和05135×0566。
36 combinations were crossed with 12 inbred lines of sweet corn by incomplete diallel crossing design. The general combining ability (GCA) ,special combining ability (SCA) and genetic parameters of seven main head characters were analyzed. The results showed that hefitability of general combining ability was higher than that of special combining ability,and six better inbred lines were selected,which were 0583,05135,05148,0569,05101,05132 and eight better hybridized combinations were selected, which were 05148 ×0581,0572 ×05132,0574 ×0569,0572 x 0569,0572 ×05133,0583 ×05133,05130 ×05101 ,05135 ×0566.
