玉米新品种晋单42号选育研究

Breeding of Jindan 42 for High Yield and Quality

晋单42号的选育以高产优质广适多抗为育种目标、性状互补共增为原则组配亲本,以稳定株数、提高粒重为模式调整产量结构,重视高效的根茎叶穗理想株型和生理协调的生长发育特性,保证综合抗性。采取产量测评、异地多点适应性鉴定及全生育期分流观察等选择方法,使育成的晋单42号产量高,品质优良,抗病性好,综合农艺性状好。

Jindan 42 is a high yield and quality maize variety aimed to ensure stable higher yield,adaptivity,quality and wide resistances.Based on complemetary characters of parents combination,yield component patters and adjusted with stable plant amount and grain weight improvement,and plant type are valued with high photosynthetic efficienty,and physiological harmony are valued,complex resistances are guaranted.The breeding procedure includes yield evaluation,adaptive identity in different sites,sysmetic observatian through the whole growth stage.With the methods,Jindan 42 was developed with stable high yield and quality,more resistances and good complex agronomic characters.
