Abstract
To study the degree of correlation between the branch traits (branch number、branch length 、branch knot number、branch seed number、branch seed weight)and yield、agronomic traits,As well as the primany and secondany relationship between characters,an experiment was operated at different plant space with two differ-ent growth tupe soybean,the correlation and grey relation were used to analyze,The result shows:(1 )The branch traits of the two soybean breed had exthemely significantly positive correlation with the main stem knod number、main stem pods with 3 seeds、main stem seed number 、main stem seed weight、seed per plant、seed weight per plant;the semi-deferminat soybean branch traits have negative correlation with the 100-seeds weight、yield,the branch traits of the indeter-minate soybean has positive correlation with the 100-seeds weight、yield,both of the two don’t reach the significant degree.(2)The grey relation degree between inteder-minate soybean agronomic traits and the branch traits is:seed number per plant >seed weight per plant >main stem knod number >main stem seeds weight >main stem seeds number >main stem pods with 3 seeds >main stem pod with 4 seeds >main stem pod with 1 seed >main stem pod with 2 seeds >plant height >yield >100-seeds weight;the branch traits of grey relation degree with agronomic traits is:branch number > branch seed weight >branch seed number >branch knod number >branch length.(3)The grey relation degree between the semi-determinate soybean agronomic traits and the branch traits is:seed number per plant >seed weight per plant >main stem pods with 3 seeds > main stem seeds number >main stem seeds weight >main stem knod number >main stem pod with 4 seeds >main stem pod with 2 seeds >main stem pod with 1 seed >plant height> yield >100-seeds weight;the branch traits of grey relation degree with agronomic traits is:branch knod number >branch number >branch length > branch seed weight >branch seed number.(4)When breeding in Hei Long Jiang province,we should base on their different pod characteristics,and close planting applied based on soybean characteristics.关键词
