Abstract:
The dry seeds of Jindou 24 had been irradiated with 60Co-γ ray,and analyzed ten main agronomic characters in the 14 soybean lines of mutants and CK using correlation analysis,principal component analysis and cluster analysis.The results of correlation analysis revealed that the seed yield per plant correlated significantly with weight per plant,branches,pods of stem,pods per plant and seeds per plant.The results of principal component analysis showed that the cumulative ratio of contribution of first three components including plant individual factors,plant shape factors and seed weight factors to the total variation reached 86.92%.The mutants weres divided into 5 groups using cluster analysis,the yield difference of each group was significant.The results of genetic relationship analysis on agronomic character showed that it was very important to cultivate new varieties.
