摘    要:针对春小麦品种产量水平提高慢,种植春小麦与其他作物比较效益低,黑龙江省小麦种植面积不断下降,引起种植业结构不合理问题,从5个方面阐述了春小麦产量突破的育种策略。从产量构成因素方面,在高收获穗数基础上,育种上应突出增加品种穗粒数的遗传改良;由于穗粒重的提高必将增大倒伏的风险,增强抗倒伏能力的育种更需加强;春小麦产量潜力的突破口在于提高春小麦品种干物质积累量方面;协调高产与稳产及产量与品质间矛盾等。

关 键 词:春小麦  产量突破  育种策略

Abstract:The paper discussed the breeding strategy for yield breakthrough of spring wheat in Heilongjiang Province from the following 5 aspects. The aim was to solve the problem of the slow increasing of yield in spring wheat cultivars, the lower interest of planting wheat comparing with other crops, and the decline of spring wheat planting area in Heilongjiang Province, which arise the irrational structure of crop cultivation. From the yield components, genetic improvement of increasing kernel number in spring wheat should be prominently enhanced on breeding, which based on high harvest amount of spikes; the anti-lodging ability of wheat cultivars must be strengthened to avoid the risk of lodging as the weight of spikes increase; the yield breakthrough of spring wheat rested with enhancing the dry matter accumulation amount; coordinating the conflict on high and stable yield with yield and quality in the genetic improvement of wheat yield.
Keywords:spring wheat  yield breakthrough  breeding strategy
