Canonical Correlation Analysis Between Quality and Yield Characters of Early Indica Hybrid Rice
He Daogen, Pan Xiaobiao, Qu Weidong (Taizhou Institute of Agricultural Sciences, Linhai 317000)
The canonical correlation analysis on 6 yield characters and 11 quality characters was conducted with the materials of 28 hybrid combinations and their 11 parents in early hybrid rice. The results showed that there existed a very significant correlation between the two groups of characters, which indicates that it is possible to develop early hybrid rice combinations with both high yield and good quality. The selection of four quality characters, i.e., head rice, chalky rice, amylose content and gel consistency should be emphasized in quality breeding. Amylose content and gel consistency should be moderate, otherwise, the improvement of other quality characters will be affected.
