Type correlation analysis between six morphological trait index and eight isozyme loci

摘要

@@ Indica-japonica differentiation is the majority for differentiation of Asian cultivated rice(O. Sativa L.). Sun et al proposed to distinguish indica and japonica by using the parameter Pj value which was quantified from six isozyme loci associated with indica and japonica differentiation, and the classification was consistent with the method of Cheng's "six combined morphological trait index" (CMT index). In this study, we analyzed the correlation between the six morphological traits and eight isozyme markers for indica-japonica classification by using 100 rice lines.
