Abstract:

The growth period of herbage is an important factor affecting the yield of forage grass. In order to breed a new variety of high-quality forage grass with short growth period and high yield,a new oat variety ‘Mengsiyan 2’ was bred from a male parent ‘Xielinuwaer’ and a female parent ‘Yong492’ using a method of interspecies crossing. ‘Mengsiyan 2’ has better saline and drought tolerance and lodging resistance. Among 2015-2016, the average fresh forage yield of 32 406.06 kg·hm-2, the average hay forage of 10 935.85 kg·hm-2 and the average grain yield of 2 364.91 kg·hm-2 were achieved, which were 19.49%, 19.22% and 5.84% higher, respectively, than that of the control. The result showed that 'Mengsiyan 2' had the growth period of 90 days, the height of 135 cm,the length of 20.4 cm,the grain number per spike of 65.5,grain weight per spike of 1.25 g, and 1000 seed weight of 31.0 g, and was suitable to Inner Mongolia and its adjacent regions.

摘要：

牧草生育期是影响牧草产量的重要因素，为了培育出生育期短、高产量的优质牧草新品种，以母本‘永492’和父本‘歇里·努瓦尔’进行种间杂交选育出燕麦饲草新品种‘蒙饲燕2号’。‘蒙饲燕2号’具有较强的抗旱耐盐以及抗倒伏能力。生产试验结果表明，2015—2016年‘蒙饲燕2号’燕麦草的平均鲜草产量、干草产量及种子产量分别为32 406.06 kg·hm-2，10 935.85 kg·hm-2和2 364.91 kg·hm-2，较对照品种分别平均提高了19.49% ，19.22%和5.84%。生育期90天， 株高135 cm，穗长20.4 cm；穗粒数65.5个，穗粒重1.25 g；千粒重31.0 g。 在内蒙古及其毗邻省区均可种植。
