宁夏引黄灌区花生引种鉴定试验OA

To expand the types and area of oilseed crops in Ningxia region,10 peanut varieties were introduced and tested for their adaptability in the Yellow River irrigation area of Ningxia.The results showed that the yield and the coefficient of variation of the number of fruits per plant of the tested varieties were relatively large,being 29.43%and 28.85%respectively;the pod yield ranged from 2 146.2 to 5 992.3 kg/hm2.The yields of'Fenhua No.21','Fenhua No.14','Fenhua No.22'and'Fenhua No.15'were significantly higher than those of other varieties,with good yield stability and productivity;the oleic acid content of'Zhonghuatian No.2'was as high as 79.96%,and the ratio of oleic acid to linoleic acid was 14.13;the protein content of'Fenhu No.22 and'Zhonghuatian No.2'was relatively high.Correlation analysis showed that yield was highly significantly positively correlated with pod width and the number of fruits per plant,while the oil content were highly significantly negatively correlated with protein content,total amino acid content and stearic acid content.In conclusion,the following peanut varieties with significant yield advantages and having potential for promotion in the Yellow River irrigation area of Ningxia were initially selected:'Fenhua No.21','Fenhua No.14','Fenhua No.22',and''Fenhua No.15';as well as the varieties with superior quality:'Fenhua No.22'and'Zhonghuatian No.2'.
