为了更全面了解凤豆十七号的特征特性,以该品种2008-2010年云南省优质蚕豆新品种联合区域试验结果为依据,通过产量、方差、变异系数和回归系数与凤豆一号(CK1)和各地主推品种(CK2)进行比较,并对产量构成因素进行相关分析和通径分析,以提出相应的高产栽培措施,利于凤豆十七号在生产中的推广应用。产量分析结果为,凤豆十七号在2008-2010年平均产量居第一位,比凤豆一号(CK1)增产15.57%,比各地对照种(CK2)增产5.95%;稳定性分析显示凤豆十七号的产量变异系数和方差最小,回归系数为1.0173,属于高产稳产型品种;产量构成因素的直接效应为百粒重>有效枝>每枝粒数。结果表明,凤豆十七号是一个丰产性好,增产潜力大,产量稳定性强和适应性广的高产品种。
In order to understand more about the characteristics of Fengyou 17 in detail, based on the regional results of the new varieties of faba bean from 2008 to 2010 in Yunnan province, the yield and variance, coefficient of variation and regression coefficients were compared with those of Fengyu No.1 ) And the main push varieties (CK2) were compared, and the yield components of the correlation analysis and path analysis in order to put forward the corresponding high-yielding cultivation measures, which is conducive to the popularization and application of Fengyu No. 17 in the production. The yield analysis showed that the average yield of Fengdou No.17 was the highest in 2008-2010, 15.57% more than that of CK1 and 5.95% higher than that of CK2. The stability analysis showed that Feng- The coefficient of variation and the variance of the yield of bean No.17 were the smallest, with the regression coefficient of 1.0173, which belonged to the high and stable yielding varieties. The direct effect of yield components was that of 100 grains per plant> effective branch> per grain. The results showed that Fengdou No. 17 was a high-yielding variety with high yield, large yield potential, strong yield stability and wide adaptability.
