摘 要 ：1983—1985年间对3份高粱 A_2不育系,及其与20份测验种组配的测交种,进行了主要农艺性状的配合力分析。结果表明,A_2TAM428和 A_2T_x3197穗粒重、穗粒数、穗长的 GCA 效应显著低于 A_1T_x622的;A_2T_x624各主要农艺性状的 GCA 效应通常与 A_1T_x622的相近。A_2TAM 428×晋粮5,A_2T_x3197×忻粮7穗粒重的 SCA 效应较高,但实际

Abstract:The combining ability for main agronomic characters of A_2T_x624,A_2T_x3197 andA_2TAM 428 as well as thier hybrids from 20 tester lines was analysed during 1983 to1985.The following conclusions were obtained:1.GCA effects of A_2TAM 428 were significantly lower than that of A_1T_x 622 forthe characte
