高粱纯系 4 0 1 1经体细胞突变筛选获得突变体Mh、Ms。用 4 0 1 1、Mh、Ms分别与 5个不育系杂交。对突变体配合力和应用进行测定 ,结果表明 ,4 0 1 1、Mh在 7个性状上的配合力较高 ,而Ms配合力较低 ,但就株高而言 ,Ms具有负优势 ,对矮秆杂交种的选育有利 Sorghum line 4 0 1 1 by somatic mutation screening mutant Mh, Ms. With 4 0 1 1, Mh, Ms were crossed with five sterile lines. The results showed that there was a high combining ability of Mh in 7 traits and a low combining ability of Ms in 4 0 1 1, but Ms had a negative superiority in plant height, Breeding of dwarf hybrids is favorable
