Abstract excerpt

BACKGROUND: The increase in the productivity of rice has become very limited due to limited major genes for key yield-attributing traits, namely, grain number per panicle, thousand-grain weight, panicle primary branching, and productive tiller number. To break this barrier, there’s an immediate demand to identify novel genes or quantitative trait loci (QTLs) from diverse germplasm. This study aims to address this...
