新疆伊犁河谷地区青贮玉米新品种筛选初报

Preliminary Report on Screening of New Varieties of Silage Corn in Yili Valley,Xinjiang

新疆伊犁河谷地区是西北重要的玉米产区之一,青贮玉米近年来在本地区发展较快。为了筛选出适合本地区推广应用的优良青贮玉米新品种,于2021年广泛收集引进21个新品种在本地区3个地点进行适应性鉴定试验。通过大区比较试验,对影响品种推广应用的主要农艺性状、抗病性、干鲜生物量以及青贮品质等指标进行测定,筛选出适合本地区种植的优质青贮玉米新品种。综合评价结果表明:‘中禾107’、‘强硕90’、‘KXA 4574’和‘中单909’这4个青贮玉米新品种在伊犁河谷地区表现出较好的增产潜力,在鲜质量和干物质质量方面较高,品质接近优质青贮玉米的标准,值得进一步推广利用。研究结果对本地区青贮玉米品种推广和促进畜牧业发展具有参考与借鉴意义。

Yili River Valley is one of the important corn production areas in Northwest China.In recent yearssilage corn has developed rapidly in this region.In order to select excellent silage corn varieties which were suitable for promotion and application in this region,21 new varieties of silage corn were widely collected and introduced in 2021 to carry out adaptability tests in three differentlocations.Several index such as main agricultural trait,resistance,silage quality,etc,were measured.The comprehensive evaluation results showed that the fournew silage corn varieties'Zhonghe 107','Qiangshuo 90','KXA 4574'and'Zhongdan 909'showed good yield potential in Yili River Valley,with high fresh weight and dry matter weight,and the silage quality was close to the standard of high-quality silage corn,which was worthy of further utilization.The results of this study have certain reference significance for the application of silage corn and the development of animal husbandry in this region.
