摘  要:
Correlations between four grain quality, 24 plant morphological traits and eight element contents of 653 accessions from Yunnan rice were analyzed. P, K, Ca and Mg contents of core collection were closely correlated to the most plant morphological and grain quality traits, and there were highly significant correlations (P < 0.01) among some traits including P content to number of stems and tillers, K content and amylose content, Ca content and plant height, Mg content and protein content. Mn, Zn, Cu and Fe contents of core collection were closely related to a few traits, such as Fe content and gel consistency (-0.1121~(**)), Zn content and seed setting rate (-0.1411~(**)), Cu content and number of grains per panicle (-0.1398~(**)), Mn content and plant height (-0.2492~(**)).
