Breeding of High-quality Early-mature Waxy Maize Va-riety “Qingnuo 1”
摘要
Abstract
Objective]New varieties of maize were bred to meet the demand from the market and planters for new high-quality early-mature waxy maize varieties.[Methods]Inbred lines QN331 and QN412 were chosen as the female and male parent for breeding in 2009.And waxy maize regional trials were conducted in spring and autumn in 2012.[Results]The newly bred high-quality early-mature waxy maize variety “Qingnuo 1”had thin skin,good appearance,good taste,and high and stable yield.Its growth duration was short.From seedling to harvest,the growth duration in south Guangxi was 74 d in spring and 70 d in autumn.The total score in re-gional trial was 86.25 points,which ranked No.1 and was 1.25 points higher than the control. The mean fresh ear yield of the two seasons was 11 145.00 kg/hm2 and 8.7% higher than the control.“Qingnuo 1”had strong resistance to northern corn leaf blight and medium resistance to stem rot.Its resistance was much better than the control,and its seed production was also higher.[Conclusion]“Qingnuo 1”,suitable for extending in different places of Guangxi,was approved and certified by Guangxi Crop Variety Committee in June,2013.关键词
