冀北坝上地区皮燕麦品种比较试验

Comparison Test of Oat Varieties in Bashang Area of Northern Hebei

筛选适合冀北坝上地区种植的优质、高产、稳产、抗逆性强的皮燕麦品种,以期促进优良皮燕麦品种的推广,对该区燕麦品种结构进行优化。对河北省高寒作物研究所提供的7个皮燕麦品种(N6为对照)进行了品种比较试验,结果表明:参试皮燕麦品种在冀北坝上地区均可以正常成熟,生育期为83~93 d。抗旱性除OT04为较强、OT06为较弱外,其他品种均为一般;抗倒性仅OT06为一般,其他品种均较强;所有品种均未观察到病害发生。生物产量和籽实产量除OT06较CK减产外,其他品种均表现增产,增幅分别为3.57%~13.31%和2.13%~19.20%。OT04的穗粒数、穗粒重和千粒重均最大,籽实产量(2850.0 kg/hm^2)最高;OT01和OT02籽实产量次之,分别较CK增加15.12%和13.36%。OT02的生物产量(26175 kg/hm^2)最高;OT01次之,生物产量较CK增加11.69%。综合分析认为,OT04籽实产量高,抗逆性较强,适合粮用;OT01和OT02生物产量和籽实产量均较高,适合粮饲兼用;其他品种可作为资源进一步利用。

Screening the high quality,high yield,stable yield, and highly stress-resistant oat varieties suitable for cultivation in Bashang area of North Hebei could promote the popularization of fine varieties and optimizing the variety structure. Seven oat varieties(N6 was CK) provided by Hebei Alpine Crop Research Institute were compared. The results showed that all varieties could mature normally with the growth period of83-93 days. The drought resistance of OT04 was strong,that of OT06 was poor,and that of others was general. The lodging resistance of OT06 was general,while that of others was strong. No disease was observed in all varieties. The biological yield and seed yield of OT06 decreased,while those of others increased than CK,which increased by 3.57%-13.31% and 2.13%-19.20%,respectively. The grain number per spike,grain weight per spike and 1 000 grain weight of OT04 was the highest,as well as its seed yield(26 175 kg/hm2). The seed yield of OT01 和 OT02 followed,which increased by 15.12% and 13.36% than CK,respectively. The biological yield of OT02 was the highest(26 175 kg/hm2), that of OT01 was the second, which increased by11.69% than CK. After comprehensive analysis,the seed yield of OT04 was high and the stress resistance was strong,which is suitable for using as grain,the biological yield and seed yield of OT01 and OT02 were high,which is suitable for using as grain and forage,and the other varieties could be further used as resources.
