Correlation of Plant Morphological and Grain Quality Traits with Mineral Element Contents in Yunnan Rice

Abstract

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