对越冬盖膜与不盖膜条件下“蓝败”、“蓝矮败”小麦不育系及其共同回交亲本进行了生育期及农艺性状的比较研究。结果表明,“蓝矮败”抽穗迟、开颖晚,常规栽培下与回交父本花期不遇,必须地膜覆盖才能花期相遇,且其群体小,制种产量相对较低;“蓝败”抽穗期、开花期均与回交父本相近,花期自然相遇,结实率高,制种产量与回交父本相当,是一个极具发展前景的不育系,有助于推动杂交小麦种植迈向市场化。
The comparative study on the growth period and agronomic traits of “blue defeat ” and “blue dwarf ” wheat sterile lines and their common backcross parents were conducted under the conditions of wintering and non-covering. The results showed that “blue dwarf defeat ” heading later, open late, under conventional cultivation and backcross parental flowering period, must be mulching to flowering met, and its small group, seed production is relatively low; “blue Lost ”heading and flowering are similar with the back to the male parent, natural encounter flowering, seed setting rate, seed yield and return to the father of considerable, is a very promising male sterile lines, contribute to promoting hybridization Wheat cultivation marketization.
