Abstract:

To discuss the difference and correlation analysis on the main agronomic traits for Trifolium repens L. germplasm resources to reveal characteristics and genetic relationship among white clover germplasm resources .The difference and correlation analysis of 12 main quantitative character of 78 (Trifolium repens L.) was carried out. The results indicated that which have the abundant genetic diversity among the varieties, between to each of quantitative characters were positively correlated, The plant height was positively correlated with leaf length, width, size and petiole length; the leaf length was significantly and positively correlated with leaf width and size, which was positively correlated with petiole length and diameter; the leaf width was significantly and positively correlated with leaf size, which was positively correlated with petiole length and diameter of flower handle; the leaf size was positively correlated with petiole length, petiole diameter and diameter of flower handle. This group of white clover germplasm materials can provide rich parents materials for White clover breeding and genetics studies.
