GD, growth duration; PH, plant height; PN, panicle number; NG, number of grains; NGP, number of grains per panicle; SF, spikelet fertility; GW, 1000-grain weight; YP, yield per plant. LH4A, Honglian-CMS line Luohong-4A; YXA, WA-CMS line Yuexiang-A; Bph68S, a two-line photo-thermo-sensitive genic male sterile line. Letters indicated a significant difference at the 5% significance level by the least significant difference test. “–” indicated no investigation results. The combinations were planted in the Wuhan University Ezhou Experimental Base in the summer of 2016.
