草燕1号燕麦新品种选育及品种特性评价

草燕1号燕麦（Avena sative‘Caoyan No.1’）是针对甘肃高寒地区及二阴地区旱作栽培条件下选育的高产、抗倒伏的燕麦新品种。该品种是以和政乡土燕麦为原始材料,采用单株混合选择法,经过近10年的选育而成。以青海444和青引1号为对照,在和政、定西、庆阳、天祝和夏河5个地点进行了品种比较试验、区域试验和生产试验。结果表明,草燕1号燕麦适宜在海拔1500~3000m的青藏高寒区和二阴冷凉区推广种植,其生育期比对照品种晚2~6d,牧草产量与对照无明显差异,但种子产量显著高于2个对照品种（P<0.05）,饲用品质优于青海444,且差异显著（P<0.05）,但与青引1号无显著差异。

Breeding and Evaluating of Variety Characteristics of Avena sativa ‘Caoyan No.1’

Avena sativa ‘Caoyan No.1’ is a new variety of oats with high-yield and lodging-resistance which was cultivated in the alpine region and Eryin region of Gansu province. This variety was made of native oat as the original material of Hezheng county using a single plant mixed selection method after nearly 10 years of breeding. Avena sativa Qinghai 444 and Qingyin No.1 were selected as control and the product ratio test, regional test, and production test were carried out in Hezheng, Dingxi, Qingyang, Tianzhu, and Xiahe. The results showed that Avena sativa ‘Caoyan No.1’ was suitable for popularizing and planting in the Qinghai-Tibet alpine area and Eryin cold area at an altitude of 1500-3000m. The phenophase of Caoyan No.1 was 2-6 days later than the control varieties. There was no significant difference between the forage yield and the control, while, seed yield was significantly higher than that of the control (P<0.05). Moreover, forage quality was significantly better than Qinghai 444 (P<0.05), but there was no significant difference with Qingyin No.1.
