Genetic Divergence Study In Bottle Gourd [Lagenaria Siceraria (Mol.) Standl.]
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 4
Abstract
An experiment was carried out to analyze the genetic diversity, for the yield and its contributing traits in fortybottle gourd genotypes, at the Main Vegetable Research Station, Anand Agricultural University, Anand, during Kharif, 2015. Forty genotypes of bottle gourds were grouped into seven clusters, through Mahalanobis D2 statistics. The clustering pattern indicated the absence of, relationship between geographical diversity and genetic diversity. The maximum genetic divergence was observed between, cluster II and IV, followed by cluster III and VII. The attributes of fruit weight, followed by total sugar content, length of pedicel, antioxidant activity, fruit length, fruit girth, number of fruits per plant and first female flowering node number contributed much to the total genetic divergence. Based on intercluster distances, crossing of the genotypes from cluster II with cluster IV, can lead to broad spectrum of variability in segregating generations, to employ selection for yield improvement.
