摘要
选用核质互作型９３０７５３雄性不育系与９４８７２０、９４８７１７、９４８７４２、９４８７９１等２０个恢复系配制成２０个杂交组合．调查了Ｆ１代６个性状的优势表现，结果表明：（１）抽穗期明显趋向早熟亲本；（２）株高、单株有效穗数、千粒重、每穗总粒数、结实率趋高亲值或超高亲值，均具有较大的中亲优势，并以单株有效穗数优势最强；（３）选到了产量构成三要素都具超亲优势的７个组合。
The heterosis of 20 crosses made with karyocyt-oplasmic interaction type MSline 930753 and 20 restorer lines was surveyed and analyzed on 6 major characters in 1996;the following results were obtained:(1)the character of days to heading for hybrids inclinedto the earlier-maturing parent.(2)The other characters of hybrids were close to or more thanhigher-parent; the heterosis on panicles per plant was the strongest.(3)7 combinationsshowing heterosis of higher-parent on three yield factors were selected.
