| 摘 要： | 相关和通径分析表明,每株粒重的超亲优势与6个其它性状的超亲优势有密切正相关。其中,每株穗数和每穗实粒数两个性状的超亲优势对每株粒重超亲优势的直接影响最大;株高居中;每株茎数和每穗小穗数的超亲优势对每株粒重超亲优势的直接影响都比较小,它们主要是分别通过每株穗数和每穗实粒数的超亲优势起间接作用;每株秆重的超亲

| Abstract: | Based on correlation study and path analysis,the transgressive het-erosis of seed weight per plant was closely and positively correlated tothat of the other six characters.Panicles per plant and plump seeds perpanicle exerted the greatest direct influence on transgressive heterosis ofseed weight per |
