Correlation studies for yield in different upland rice (Oryza sativa L.) genotypes of Nagaland

Author(s):
B Lalhruaitluangi, MB Sharma and Pankaj Shah
Abstract:
Yield and yield contributing traits of 28 upland rice genotypes were studied in Experimental Farm, Department of Genetics and Plant Breeding, SASRD, Nagaland University, Medziphema. The experiment was conducted in Kharif 2021 among the yield and yield contributing traits viz., days to 50 percent flowering, days to maturity, plant height (cm), flag leaf length (cm), flag leaf breadth (cm), flag leaf area (cm2), no. of ear bearing tillers, panicles per plant, panicle length (cm), panicle weight (g), spikelet fertility, root dry weight (g), stem dry weight (g), harvest index, total nitrogen (%), crude protein, 100 grain weight (g) and Grain yield per plant (g). Days to 50% flowering and days to maturity shows positively significant association with grain yield per plant and plant height, flag leaf length and flag leaf area also shows positive significant association with 100 grain weight highlighting the significance of these features as criterion for selection in yield improvement programmes.
