Study on the correlation between some agronomiccharacters,yield and quality of seven feeding oatvarieties in liupanshan,ningxia

摘要:

对7个饲用燕麦品种的若干农艺性状、草产量、营养品质进行评价与筛选,并对各指标的相关性进行统计分析,以筛选出综合表现优良的饲用燕麦品种。结果表明:综合表现优良的品种是甜燕2号、甜燕1号、牧王;旗叶叶面积与粗蛋白含量极显著正相关,鲜干比与粗纤维极显著正相关,干草产量与中性洗涤纤维极显著正相关,与相对饲用价值显著负相关,相对饲用价值与中性洗涤纤维极显著负相关,与酸性洗涤纤维显著负相关。

Abstract:

Seven feeding oat varieties were evaluated and screened for some agronomic characters,grass yield and nutritional quality,and their correlation.The results from the grey correlation comprehensive analysis showed that Tianyan No.2,Tianyan No.1 and Haymaker had the best performance.And the the results from pearman rank correlation analysis showed that there were significant positive correlation between the flag leaf area and CP(crude proteiu) content,the ratio of fresh to dry weight and CF(crude fiber),the hay yield and NDF((neutral detergent fiber)).Meanwhile,there were significant negative correlation between hay yield and RFV(relative feeding value),RFV and NDF,RFV and ADF(acid detergent fiber).
