摘要
用雄性不育系陕２Ａ与早熟低芥亲本２２７３—３杂交，连续回交五代，获得了不育性状稳定的不育系８９Ａ。８９Ａ与恢复系９０—５９５Ｃ组配的强优组合杂优１３，具有早熟、抗寒、丰产稳产、低芥酸等特性。１９９１—１９９４年多点试验、示范结果，杂优１３平均亩产１８８．８ｋｇ，比秦油二号增产５．１％，早熟３—５天。
A male sterile line Shaan 2A was crossed with a low erucic acid and early maturing genotype 2273-3.The hybrid was consecutively backcrossed for five generations,and a stable male sterile line 89A was selected.A hybrid cultivar Zayou 13 was identified from the combination between 89A and a restoring line 90-595C.Zayou 13 showed high yield,tolerance to cold,early maturity and low erucic acid in various trials across locations and seasons.
