Unraveling The Genetics Of Rice (Oryza Sativa L.) Yield And Its Component Traits

Abstract

In the Hadoti region of Rajasthan, rice (Oryza sativa L.) crosses were grown in a Randomized Block Design for the purpose of estimating correlation and path coefficient in an experimental study. An examination of variance data demonstrated that there were noteworthy distinctions among all genotypes with respect to the traits that were studied. The correlation or association studies disclosed that the relation of grain yield per plant was positively and significantly at phenotypic and genetic level with characters viz. number of effective tillers per plant, panicle length, number of spikelets per panicle, test weight and kernel length. The highest positive direct impression/ effect on grain yield was recorded for number of spikelets per panicle, panicle length, kernel length and number of effective tillers per plant.
