Abstract:
374 hybrids from 5 hybrid combinations were used as test materials,10 leaf and fruit traits were investigated and measured,and the correlation among them were analyzed to provide theoretical basis for walnut breeding and early selection.The results showed that the phenotypic correlation and genetic correlation between nut weight and nut transverse diameter,nut longitudinal diameter,nut shell thickness were all significant;the correlation between leaf traits and nut weight was not significant.The results of path analysis showed that the path coefficient of nut transverse diameter,nut longitudinal diameter,nut shell thickness and specific leaf weight to nut weight was 0.160 4,0.626 3,0.290 8 and -0.163 9 respectively.These four factors contributed significantly to the nut weight and were the main factors affecting the nut weight of walnut.
