试验结果表明：不育系Ｌｕ１Ａ的株高、生育期的一般配合力低于６２３Ａ，达极显著水平，而产量、穗粒数的一般配合力高于６２３Ａ，达显著或极显著水平，可望替代６２３Ａ成为高粱夏播区配制高产、早熟、矮秆杂交种的骨干不育系。恢复系材料中，６００６的穗长、千粒重、熟期的一般配合力表现突出，与其他材料差异达显著或极显著水平。晋８９３４６的产量一般配合力效应值最高，株高的一般配合力效应值最低，穗粒数显著高于对照，应用潜力较大。参试组合中，６２３Ａ×晋８９３４６、Ｌｕ１Ａ×晋８９３４６等组合产量居前几位，综合性状较好
The results showed that the general combining ability of Lu1A in sterile line was lower than that in 623A at the growth stage, reaching the extremely significant level. The general combining ability of yield and grain number per spike was higher than 623A, Replacing 623A into a sorghum summer sowing area to prepare high yielding, early maturing, dwarf hybrids. In restorer materials, 6006 spike length, 1000-grain weight, maturity general combining ability outstanding performance, and the difference with other materials reached significant or extremely significant level. Jin 89346 had the highest general combining ability effect value, the lowest general combining ability effect value of plant height, the spike grain number was significantly higher than the control, and the potential for application was relatively high. Among the tested combinations, 623A × Jin 89346, Lu1A × Jin 89346 and other combinations yield the top few, the comprehensive traits are better
