Production Performance Comparison of Forage Broad Bean in Western Hunan
In order to screen forage broad bean(Vicia faba)varieties suitable for spreading and application in winter fallow fields in Western Hunan,the plant height,branch number,fresh weight of 100 seeds,dry weight of 100 seeds,fresh yield,hay yield and dry matter content of 10 broad bean varieties(Qingcan No.13,Qingcan No.14,Qingcan No.15,Qingcan No.16,Qingcan No.19,Tongcanxian No.6,Tongcanxian No.7,Tongcanxian No.8,Yiyang big grain,Yiyang small grain)were determined and analyzed,and the grey relational degree was used to comprehensively evaluate the 10 broad bean va-rieties.The results showed that the plant height range of 10 broad bean varieties was 77.17-91.20 cm,the number of bran-ches was 3.13-5.93 piece of per plant,the fresh weight of 100 seeds was 135.00-358.00 g,the dry weight of 100 seeds was 30.33-109.33 g,the fresh yield was 13.04-21.58 t/hm2,the hay yield was 2.59-4.31 t/hm2,the dry matter content was 16.91%-22.92%,and the plant height of Qingcan No.19 was the highest,which was 91.20 cm,Qingcan No.16 had the highest number of branches,the highest fresh and hay yields,5.93 piece of per plant,21.58 and 4.31 t/hm2,respec-tively,the fresh weight of 100 seeds of Tongcanxian No.8 was the highest,which was 358.00 g,the dry weight of 100 seeds of Yiyang small grain was the highest,which was 109.33 g,and the dry matter content of Tongcanxian No.6 was the hi-ghest,which was 22.92%.Comprehensive evaluation shows that Qingcan No.16 has the best performance and Tongcanxian No.7 has better performance,which can be therefore recommended as suitable to be planted more widely in winter fallow fields in Western Hunan.
