Genetic analysis for yield and quality traits in Bottle gourd

Abstract

The present investigation entitled Genetic analysis for yield and quality traits in Bottle gourd [Lagenaria siceraria (Mol.) Standl.] were conducted at main experiment station, Department of Vegetable Science, Kalyanpur, C. S. Azad University of Agriculture and Technology, Kanpur-208002 (U.P.). India during Zaid, 2021. Ten diverse genotypes of bottle gourd have crossed in diallel mating design (excluded reciprocals) to produce 45 F1s hybrids for source seed of F2 during Zaid 2020. All the ten parents, 45 F1s and 45 F2s were grown in Randomized Block design with three replications. Observations were recorded on fifteen qualitative and quantitative characters viz., node number to first staminate flower appears, node number to first pistillate flower appears, ratio of pistillate : staminate flowers, internodal length (cm), vine length at last picking stage (m), number of primary branches per plant, days to first fruit harvest, average weight per fruit (kg), number of fruits per plant, fruit diameter (cm), fruit length (cm), duration of crop (days), total soluble solids (TSS) 0Brix, specific gravity of fruits (g/cc) and fruit yield per plant (kg). The data of quantitative and qualitative traits were analysed to fulfil the following objects: (i) to estimate genetic variability, genetic variance in parents newline
