This study was carried out to determine direct and indirect effects of some characters (Days to 50% flowering, plant height (cm), Number of monopodial branches per plant, Number of Sympodia per plant, Number of bolls per plant, Mean boll weight (g), Ginning percentage, Seed index (g) and Lint index (g)) on seed cotton yield. The experiment was carried out with 48 F 1 hybrids have produced through Line×Tester mating design using 6 hirsutum non Bt lines (RAH 318, RAH 243, RAH 128, RAH 146, RAH 97 and RAH 124) and 8 hirsutum non Bt testers ( SC 14, SC 18, SC 7, SC 68, RGR 32, RGR 24, RGR 58 and RGR 37)were sown in a randomized complete block design (RCBD) with two replications at the Agricultural Research Station, Bavikere, UAS, Bangalore.
An experiment was conducted to examine the performance of eight cowhage (Mucuna pruriens L.) genotypes for their growth and flowering parameters in arecanut plantation under hill zone of Karnataka. Significant differences were observed in genotypes with respect to growth and flowering attributes. The genotype Arka Dhanvantari recorded the maximum plant height (282.03 cm) and number of trifoliate leaves (71.03) at harvest. The maximum leaf area (20064.39 cm2), leaf area index (7.43) and leaf area ratio (246.25 cm2/g) was recorded in genotype Arka Dhanvantari. The maximum absolute growth rate (1.38 g/plant/day) and crop growth rate (5.12 g/plant/day) was recorded in genotype IIHR Selection-2. The days taken for first flowering and 50 per cent flowering were minimum (65.73 and 72.33, respectively) and maximum (132.20 and 140.67, respectively) in the genotypes Arka Aswini and Arka Dhanvantari, respectively. The maximum number of inflorescence per plant (8.30) was recorded in genotype IIHR Selection-2. Genotype Arka Dhanvantari recorded maximum number of flowers per inflorescence (15.50) and inflorescence length (18.10 cm).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
