May 01, 2020  Phenotypic evaluations also showed that qSBN7 had pleiotropic effects on secondary branch number per panicle, grain number, grain length, 1000-grain weight, and the percentage of filled grains. Our results suggest that qSBN7 increases reproductive sink capacity in rice and can be applied in breeding new elite cultivars.

Colored rice is rich in nutrition and also a good source of valuable genes/quantitative trait loci (QTL) for nutrition, grain quality, and pest and disease resistance traits for use in rice breeding. Genome-wide association analysis using high-density single nucleotide polymorphism (SNP) is useful in precisely detecting QTLs and genes.
