Genetic divergence analysis in bottle gourd [Lagenaria siceraria (Mol.) Standl.]
##plugins.themes.bootstrap3.article.main##
Abstract
The study was conducted during summer 2014-15 at the Instructional Farm, College of Agriculture, Junagadh Agricultural University, Junagadh to assess the genetic diversity among 50 genotypes of bottle gourd (Ligenaria siceraria L.). The genetic diversity analysis revealed the formation of 13 clusters suggesting the presence of wide genetic diversity. The clustering pattern indicated that geographic diversity was not associated with genetic diversity. The analysis of per cent contribution of various characters towards the expression of total genetic divergence indicated that number of fruits per vine (22.45%) followed by number of primary branches per vine (13.80%), average fruit weight (11.51%), vine length (11.18%), fruit yield per vine (10.61%), number of male flowers (7.84%), fruit length (6.45%), ratio of male to female flowers (4.82%), days to first picking (4.49%) and days to opening of first male flower (3.84%) contributed maximum towards total genetic divergence. Based on the maximum genetic distance. It is advisable to attempt crossing of the genotypes from cluster XII(GP-14) with the genotypes of cluster IV (GP-25) and XI (GP-53), which may lead to the generation of broad spectrum of favourable genetic variability for yield improvement in bottle gourd.
