Evaluation of spine gourd genotypes for variability

K. A. Archana, K. P. Prasanna, T. E. George


Thirty one accessions of spine gourd collected from different parts of Kerala were grown with objectives of genetically cataloguing the germplasm and to assessing genetic variability, heritability, genetic gain and correlating different traits with yield. High genotypic and phenotypic coefficient of variation was observed for days from flowering to vegetable maturity, total number of harvests and fruit length. Yield exhibited genotypic correlation with number of branches per plant, total number of harvests, fruit length and number of fruits per plant. In path coefficient analysis the highest positive direct effect on yield was exhibited by total number of harvests followed by fruit girth.
