摘要
用6个细胞质雄性不育系与5个恢复系配置30个杂交组合,对这些杂交组合的16个农艺性状进行了2 a重复鉴定。应用灰色关联分析法对这30个杂交组合进行综合评价,结果表明,在30个油菜杂交组合中,有8个一等组合,15个二等组合,7个三等组合;在亲本方面,以L451和L89作母本较好,以L161、秦油3号作父本较好,杂交后代均有不同程度的杂交优势,其中L89×L161的杂交优势最高,L161可作为亲和力较高的自交系。
Six male-sterile lines carrying the widely used Shaan2A cytoplasm were crossed with five restorer lines to produce 30 F1 hybrids. The 30 hybrids were evaluated for sixteen agronomical traits at Yangling, Shaanxi province in Northwest China for two years. Grey relational analysis showed that, among 30 hybrid combinations, eight were grouped as the best group, fifteen the second group and sev- en the third group. Among 30 hybrids, L89×L161 was the best one. As for the parents lines, L451 and L89 were identified as the best female parents, L161 and Qinyou 3 as the best male parents. Therefore, this research will provide certain reference value to the rape hybrids＇ selection and parent choice match.
