梦龙燕麦区域试验报告

Regional Test Report of Avena sativa L. cv. Magnum

为进一步评价梦龙燕麦的饲草产量,品种丰产性、稳定性、适应性等综合指标,课题组于2015～2016年,选用阿坝、青海444和青燕1号3个燕麦品种为对照,分别在阿坝州红原县、甘孜州道孚县、凉山州布拖县共3个试验点进行了梦龙燕麦多年多点的区域试验。结果表明,各试验点各年内梦龙燕麦鲜草和干草产量均显著高于对照品种,平均鲜草产量和干草产量分别可达38 230. 47kg/hm^2和11 657. 40kg/hm^2,鲜草和干草产量比阿坝燕麦分别增产63. 57%～86. 53%和51. 66%～93. 62%,比青海444分别增产42. 87%～57. 33%和21. 94%～69. 49%,比青燕1号分别增产25. 65%～78. 66%和21. 17%～59. 14%。各点各年内梦龙燕麦草产量较对照品种具有突出的丰产性和稳定性,综合评价结果为"很好",在阿坝红原、甘孜道孚和凉山布拖3个区域适应性良好。

In order to further evaluate the comprehensive indexes of yield,stability and adaptability on Avena sativa L.cv.Magnum in different regions.From 2015 to 2016,selection of regional test of Magnum were conducted at Hongyuan county of Aba prefecture,Daofu county of Ganzi prefecture and Butuo county of Liangshan prefecture.and tree oats of Aba;Qinghai NO.444;Qing yan NO.1 were used as control varieties.Through regional tests showed that Magnum forage yield was better than the control,the fresh yield and hay yield of Magnum were 38230.47kg/hm^2 and 11657.40kg/hm^2,which were significantly higher than the control varieties.According to a comprehensive analysis,Magnum had a outstanding yield and stability,and the comprehensive evaluation result was“very good”,it could be very well adapted in different regions for testing.
