摘要
康玉1号是四川省甘孜藏族自治州农业科学研究所选育的适宜川西北高原山区种植的高产、优质、多抗玉米杂交种。在2008—2010年甘孜州杂交玉米早熟组的区试和生产试验中,居参试品种第1位,2年区试平均产量8 683.88 kg/hm2,较对照阿单9号增产13.72%;生产试验平均产量9 112.14 kg/hm2,比对照阿单9号增产7.82%。5个试点全部增产,其中3个试点是第1位。该品种种子顶土能力强,幼苗生长健壮,耐密植,高产稳产,品质优良。2013年11月已通过四川省农作物品种审定委员会审定。在川西北高原特别是甘孜州玉米产区具有广阔的推广应用前景,将推动川西北高原特别是甘孜州高山区玉米产量水平的大幅提高。
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/hm^2,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/hm^2,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.
