摘 要: | 从高芥酸自交不亲和系1010中系统选育出低芥酸自交不亲和系101O-1和1010-2,其配合力均高于亲本系1010。利用这两个系作母本同低芥酸品系或品种杂交具有较高而普遍的超亲优势率和对照优势率,优势杂交组合101-1×79C-30在两年多点试验中,在几个试点产量超过对照15%以上,最高超过54.84%。

Studies on Selections and Utilizations of Lower Erucic Self-incompatible Lines 1010-1 and 1010-2 of Rape(Brassica napus) |

Abstract: | The lower erucic self-incompatible lines 1010-1 and 1010-2 were selected from high-er-erucic self-incompatible line 1010 and their combining abilities were higher than that of the par ent line 1010.Crossing the two lines with lower erucic lines or varieties. the higher super-parent het-erosis rate and check heterosis rate emerged. The yield of the heterosis combination 1010-1×79 c30 was 15%more than the cheek(the highest was 54.8%),in many regional tests for two years. |
