【摘要】 选取18份燕麦属种质材料对其生长发育特性、种子产量构成、生产性能等进行了鉴定评价,发现其中的3号(裸燕麦杂交6代)、5号(裸燕麦杂交7代)和10号(裸燕麦杂交7代)材料可以作为燕麦籽实高产的优良材料;12号(草原所60号杂交种)材料表现晚熟,营养生长期较长,叶量丰富,干草产量较高,适宜作牧草;影响单株种子产量的主要因子是小花数/穗、种子数/穗、绝对高度及花序长。更多还原

【Abstract】 Eighteen germplasm resources of Avena were identified in growth and development characteristics,seed yield components and productive performance.Of which No.3,5,10 have high seed yield.The No.12 has abundant leaves and the higher hay yield,which is the serotinous forage with the longer nutrient growing period.The results showed: the inflorescence length,flower number per spike,seed number per spike and absolute height were the key factors for seed yield of single plant.更多还原
