为了解构成绿豆单株产量诸因素间的关系,为育种提供科学的参考依据,我们对1986年种植的61份原始材料的考种结果进行了数理统计分析。(一)构成单株产量诸因素间的关系构成绿豆单株产量的因素是单株荚数(x_1)、单荚粒数(x_2)和百粒重(x_3),其回归方程为:y=-0.0698+0.3610x_1+0.1414x_2+0.5753x_3从标准偏回归系数 by_1=0.7131,by_2=0.0869,by_3=0.2051可以看出,单株荚数对单株产量的直接效应最大,其次是百粒重,单荚粒数最小。可见,提高单株产量的关键是增加单株荚数。也就是说除选育多荚型品种外,还要加强栽培管理,尽量减少落花落荚。
In order to understand the relationship between the factors which constitute the yield per plant of mung bean and provide a scientific reference for breeding, we conducted mathematical statistics analysis on the test results of 61 raw materials planted in 1986. (A) the relationship between the factors that constitute the yield per plant The factors that make up the yield per plant are the number of pods per plant (x_1), the number of single pods (x_2) and the weight per 100 seeds (x_3), and the regression equation is y = -0.0698 + 0.3610x_1 + 0.1414x_2 + 0.5753x_3 From the standard partial regression coefficients by_1 = 0.7131, by_2 = 0.0869, by_3 = 0.2051, we can see that the direct effect of pods per plant on the yield per plant is the largest, Single pods minimum number of particles. Visible, raise the key to yield per plant is to increase the number of pods per plant. In other words, in addition to breeding more pod varieties, but also to strengthen the cultivation and management, to minimize falling falling pods.
