通过对K、Veo、Q3种新型不育系在同一保持系条件下的生长势及灌浆速度的测定,结合单倍体频率、恢复性等比较研究,认为:粘果山羊草和偏凸山羊草对普通小麦细胞质的不良效应是植株生长势弱和易产生单倍体,在配制杂交种时,应注意选用对上述异质效应有修复能力和对Ptg基因的抑制作用的恢复系,同时强调适时人工辅助授粉;野生燕麦细胞质的不良效应是籽粒灌浆速度较慢,配制杂交种时,应注意选配灌浆速度快的恢复系;K、Ven型不育系恢复源虽广,但高恢材料不多,尤其要注意恢复性的稳定性培育;Q型不育系的恢复系虽少,但其恢复度高而稳定,应进一步研究。
Through the determination of growth potential and filling speed of K, Veo, Q3 new sterile lines under the same maintainer condition, combined with the comparative study of haploid frequency and recovery, it is considered that: Amoeba and Aegilops sinensis The adverse effect on the cytoplasm of common wheat plants is weak and easy to produce haploid, in the preparation of hybrids, should pay attention to selection of the heterogeneous effect of repair ability and restorer of the Ptg gene restorer, while emphasizing the appropriate Artificially assisted pollination; wild oat cytoplasm adverse effect is the grain filling rate is slow, the preparation of hybrids, should pay attention to matching the filling speed of the restorer line; K, Ven-type sterile line, although the restoration of a wide source, but the high-material is not In particular, attention should be paid to restore the stability of breeding; Q type sterile lines restore the system is small, but its recovery is high and stable, should be further studied.
