Correlation of biological, biochemical and technological quality traits of germplasm of the rice collection
Collection of Oryza sativa L. total more than 7.0 thousand samples was formed in the All-Russian Rice Research Institute. Based on the complex of biological, biochemical and technological traits, a comparative evaluation of 112 rice samples of Indica and Japonica subspecies from remote regions of world rice growing in the conditions of southern Russia was carried out. The paired correlations between the traits are determined. Genotypic variation of amylose content was in the range of 16.8 - 31.4%, protein - 7.2 - 11.2%. Promising genotypes that combine high levels of protein and amylose for quality breeding have been identified.
