Screening Test of Spring Sowing Alfalfa Varieties in Western Henan
摘要
Abstract
In order to screen high-yield and high-quality alfalfa varieties suitable for spring sowing in western Henan,the 27 alfalfa varieties from home and abroad(Strong hold,Reindeer,Juneng 995,WL440,SW8421S,SW425,SW6330,WL363HQ,WL919,Andona,Juneng 601,Jinneng 5010,Longdong,Juneng 418,hf2110,Jinneng 211,Claudie,Saidi NO.10,601,SW5213,SW9720,Ausin118,Juneng Salt-tolerant Star,Jinneng 4.2,Caoyuan NO.3,Jinneng 806,Aohan)were selected and were cut for four times.The plant height,fresh yield,hay yield,fresh-dry ratio,stem mass,leaf mass,stem-leaf ratio,crude ash content,crude protein content,crude fat content,neutral detergent fiber content,acid detergent fiber content,relative feeding value,equal weight correlation degree and weighted correlation degree were investigated and calculated.The 27 alfalfa varieties were comprehensively evaluated by variance analysis,correlation analysis and grey correlation analysis.The results showed that the first crop of SW9720,the second crop of Jinneng 806,the third crop of WL919,the fourth crop of Saidi NO.10 had higher plant height.In terms of fresh yield,the first,second and fourth crops of Juneng 601 and the third crop of Juneng 995 had higher fresh yield,Juneng 601,WL440,Juneng 995 and WL919 had higher fresh yield throughout the year.In terms of hay yield,the first crop of Reindeer,the second crop of Juneng 601,the third crop of WL363HQ and the fourth crop of Strong hold had higher hay yield,Juneng 601,Juneng 995,WL363HQ and Strong hold had higher hay yield throughout the year.In terms of fresh-dry ratio,the first crop of WL440,the second crop of SW8421S,the third crop of Caoyuan NO.3 and the fourth crop of Jinneng 211 had higher fresh-dry ratio.In terms of correlation of agronomic traits,plant height was significantly positively correlated with stem mass and leaf mass,and extremely significantly positively correlated with fresh yield and hay yield.The stem-leaf ratio was extremely significantly negatively correlated with leaf mass and extremely significantly positively correlated with stem mass.The fresh yield was extremely significantly positively correlated with hay yield,stem mass and leaf mass.The hay yield was extremely significantly positively correlated with stem mass and leaf mass.In terms of nutritional components and relative feeding value,Juneng 418 had the highest crude ash content,WL440 had the highest crude protein content,Aohan had the highest crude fat content,Jineng 5010 had the highest neutral detergent fiber content,SW6330 and Caoyuan NO.3 had relatively high acidic detergent fiber content,and WL440 had the highest relative feeding value.In terms of perspective of comprehensive performance evaluation,the equal weighted correlation degree and weighted correlation degree of WL440,Juneng 601,WL919,Jinneng 4.2 and Juneng 995 were higher.By comprehensive evaluation,Juneng 601,WL440 and WL919 have high yield,high feeding value and yield stability of cutting stubble,which are suitable for planting in western Henan.关键词
