Genetic variability, heritability in narrow sense & Genetic advance percent of mean in bitter gourd (Momordica charantia L.)

Author(s): Narendra Kumar Tiwari, AK Pandey, UN Singh and VB Singh
Abstract: The present investigation was carried out in two years with aims to determine, Genetic variability and heritability in narrow sense involving 9 parental lines viz., NDBT-7, NDBT-9, NDBT-3, NDBT-2, Pusa Do Mausmi, NDBT-12, NDBT-1, K. Sona, NDBT-5 of bitter gourd at MES Vegetable Science N.D.U.A. & T. Kumarganj, Faizabad (U.P.) during summer 2011 and 2012. The experiments were laid out in RBD with three replications single row plot with 3 m x 0.5 m spacing. Observations were recorded on 13 characters viz. node number to first staminate and pistillate flower anthesis, days to first staminate and pistillate flower opening, days to first fruit harvest, number of primary branches per plant, node number of first fruits set, vine length (m), fruit length (cm), fruit diameter (cm), number of fruits per plant, fruits, fruit weight (g), yield per plant (kg). The analysis of variance due to genotype, parents, hybrids and parents vs. hybrids were found almost highly significant for all the characters, except due to parents vs hybrids for days to first staminate flower opening and node number to first staminate and pistillate flower appearance in both the years during 2011 and 2012. High estimate of genotypic as well as phenotypic coefficients of variability were observed for fruit yield per plant and number of fruit per plant during 2011 and 2012. The phenotypic coefficients of variability were only higher for fruit yield per plant during 2011. Moderate variability showed in fruit yield per plant Rest of characters showed low coefficient of variability.
