本文用冬小麦(洛夫林18×5238-036)_(F1)×红良4号F_1花药接种到N_6培养基上,获得46株绿菌,绿菌诱导率为11.5％。其中28株结实。于H_2代选出京花1号,经H_3,H_4,H_5和H_6代的品种比较和区域试验,京花1号表现出高产质佳,抗病性好,适应性较广等特点。现已通过品种审定委员会的审定,1984年种植面积达100万亩。京花1号的培育仅用了7个世代,表明花培育种可以显著缩短育种周期。本文还讨论了花培育种的优越性。
In this paper, 46 strains of green bacteria were inoculated on N_6 medium with F1 anther of winter wheat (Lovelin 18 × 5238-036) _ (F1) × Hongliang 4, the induction rate of green bacteria was 11.5%. 28 of them are strong. After H_3, H_4, H_5 and H_6 generations were selected for comparison and regional experiments, Jinghua 1 showed high yield, good disease resistance and wide adaptability. Has now passed the validation of species validation committee, 1984 acreage of 100 acres. The cultivation of Jinghua 1 took only seven generations, indicating that flower breeding can significantly shorten the breeding cycle. This article also discusses the advantages of flower breeding.
