Abstract
Kangyu No.1,bred by Agricultural Sciences Research Institute of Ganzi Tibetan Autonomous Prefecture in Sichuan Province ,is a hybrid corn variety with characteristics of high yield ,early maturing and high resistance to diseases. In 2008-2010 early maturing corn regional trial of Ganzi Tibetan Autonomous Prefecture ,the performance of Kangyu No.1 ranked first. The average yield of Kangyu No.1 in the two-year reached 8 683.88 kg/hm2,and compared with the control ,the yield of Kangyu No.1 increased by 13.72%. In the production experiment ,its average yield was 9 112.14 kg/hm2,increasing 7.82% by average against the control Adan No.9.Its yield was higher than the control at all 5 experimental sites ,and performed best at the 3 sites. Kangyu No.1 showed excellent performance in many aspects (strong seed emerging vigor from soil ,strong and well-growing seedings,high planted density tolerance,high and stable yield,good quality).In November 2013,Kangyu No.1 passed examination and approval to extension of agricultural variety approval commission in Sichuan Province. The new variety of Kangyu No.1 is a great achievement of highland corn breeding. It has great potential to be extended to northwest plateau of Sichuan Province especially in Ganzi Tibetan Autonomous Prefecture,will greatly contribute to yield increase of corn in a large scale in those northwest plateau.关键词
