目前,在国内外多数国家虽已完成冬性或春性小麦的三系配套任务,又测配了大量组合,但经试种超标优势还不够显著,尚未突破生产应用关。为此,最近几年我们开始对春、冬性小麦杂交优势进行了探讨。将当地优良春麦试材转育不育系,再将适合当地种植的弱冬恢复系进行筛选后累加或参与小黑麦、小偃麦等不同血统的选择。春、冬性杂交种,目前,在国内外生产上还未能利用的原因,是由于存在着亲本的选择与在春播时冬性恢复系能否通过春化阶段,以及在双亲制种时花期能否相遇,再者 F_1代优势能否达到标准。根据最近几年我们的探索,认为利用春性小麦不育与弱冬性恢复测配的组合杂交种 F_1 At present, although most countries at home and abroad have completed the three-line matching task of winter or spring wheat and tested a large number of combinations, the superiority of over-standard test is not yet significant enough to break through the production and application. To this end, in recent years we began to spring and winter wheat hybrid advantages are discussed. The local excellent spring wheat test material sterile CMS, and then suitable for local cultivation of weak winter restorer screening for the cumulative or participate in the selection of triticale, linolenic and other different lineage. Spring and winter hybrids, at present, at home and abroad have not been able to use the production of the reason is due to the existence of the choice of parents and in spring when the winter restore line through the vernalization stage, and when the parents planted flowering Can meet, in addition F_1 superiority can meet the standard. According to our exploration in recent years, it is considered that the combination of spring wheat sterility and weak winter restore test hybrid F1
