塔额盆地食用向日葵品种产量敏感性分析
Yield Sensitivity Analysis of Edible Sunflower Varieties in Taʼe Basin
摘要
Abstract
In order to ensure the high yield of edible sunflower in Taʼe basin,and explore the yield sensitivity of edible sunflower,the related traits affecting yield were investigated during the growth period.The 27 varieties of edible sunflower in Xinjiang were selected,and the genetic correlation and path coefficient between 11 main traits and yield were analyzed.The results showed that the four trait variables of grain weight per head,seed-setting rate,plant height and 100-grain weight were significantly correlated with yield,and the direct effect coefficients of yield were 0.7082,0.2742,0.2039 and-0.3381,respectively and the indirect effect coefficient was between-0.1999 and 0.5935.Path analysis further conducted on the basis of genetic correlation analysis showed that the three variables most sensitive to yield were grain weight per head,seed-setting rate and plant height.The traits with low sensitivity to yield included seed kernel rate,grain width and number of grains per head.As a result,it is preliminarily concluded that in the breeding of edible sunflower,varieties with heavy grain weight per head,high seed-setting rate,and suitable plant height must be chosen in order to ensure high yield.Other traits should be taken into consideration,and the relationships among various traits must be coordinated.关键词
