Abstract:

In order to evaluate the sorghum parents scientifically and accurately, provide the basis for making use of materials, for further improving quality breeding efficiency, three sterile lines and five restorer lines were chosen, 15 hybrid combinations were matched by incomplete diallel crosses method in this study. The brewing qualities about protein, fat, starch, tannic were analyzed by combining ability. The results showed that, in the three sterile lines, ‘Liao3401A’ exhibited higher general combining ability in protein, fat and tannic. ‘Hu45A’ only presented higher general combining ability in starch. In the five restorer lines, 741324 presented higher general combining ability in tannic. R111 showed higher general combining ability in fat and tannic. 038R and C52R-11 showed higher general combining ability in starch. ‘961541/0-30 red grain’ showed higher general combining ability in protein and fat. The order of VA/VG (the ratio of additive genetic variance to genotype variance) was as follows, protein, starch, fat, tannic.
