The current investigation was undertaken with eighteen elite rice genotypes to study the genetic diversity, variability, heritability and advance for yield attributing traits. ANOVA revealed significant variability among traits studied. 1000 seed weight is having highest phenotypic coeffcient variation genotypic (24.882 & 24.835) followed by grain per plant (20.315 19.523 respectively). Her...

Production and productivity of upland rice is still very low due to limited water in the ecosystem. The objective this study was evaluate yields varieties at several levels soil content. experiment conducted Growth Centre LLDIKTI Wilayah I Medan from March July 2013. This research used a factorial randomized block design with two factors replicated three times. Five as first factor, namely Batu...

The research work was executed Research cum Instructional Farm, Genetics and Plant Breeding department of IGKV Raipur (C.G.) during kharif 2021. material under comprised 50 rice germplasm lines including two checks namely Mahamaya Rajeshwari, which were tested in RBD with replications. observation investigation recorded for total eight characters viz. Days to 50% flowering, Number tillers per p...

At the Field Experimentation Centre of Department Genetics and Plant Breeding, 20 rice genotypes, including one check variety, were assessed in order to research genetic variability, heritability, progress, correlation, path coefficient for 13 quantitative features. In Kharif 2022, experiment was carried out utilising a Randomised Block Design with three replications. Over NDR 359 (check), BRRI...

Eight quantitative traits of an F2 MAGIC population in rice were subjected to analyze variability, correlation and path analysis. The results third fourth degree statistics (skewness kurtosis) showed that Individual dried straw weight, 1000-seed grain yield, Number effective tillers are associated with complementary gene interaction, requiring intense selection, while Plant height, Panicle leng...

Although rice yield has been doubled in most parts of the world since 1960s, thanks to the advancements in breeding technologies, the biological mechanisms controlling yield are largely unknown. To understand the genetic basis of rice yield, a number of quantitative trait locus (QTL) mapping studies have been carried out, but whole-genome QTL mapping incorporating all interaction effects is sti...

ABSTRACT The objective of this study was to determine the effect of silicon (Si) and rice growth stages on tissue susceptibility to sheath blight (Rhizoctonia solani Kühn) under controlled conditions. Rice plants (cv. Rio Formoso) were grown in pots containing low-Si soil amended with Si at 0, 0.48, 0.96, 1.44, and 1.92 g pot(-1) and inoculated with R. solani at the following days after emergen...
