Abstract:
The investigation was carried out at Vegetable Research Station, Junagadh Agricultural University, Junagadh (Gujarat) during late kharif 2017- 18 in Randomized Block Design with three replications. The experiment was conducted to assess selection indices and genetic diversity in Indian bean. The experimental materials comprised of thirty six genotypes and four check varieties. Thirty one selection indices, including green pod yield per plant and four component traits were constructed using discriminant function technique. The selection index based on five characters viz., green pod yield per plant, days to last picking, number of pickings, number of pods per plant and pod length were the most efficient one for obtaining higher yielding lines so, while making selection the maximum weightage should be given to these attributes. The most productive 40 genotypes of Indian bean were grouped in two clusters using D²- analysis. The maximum intra cluster distance was observed in cluster I. The attributes viz., twig length, number of primary branches per plant, pod length and 10- green pod weight contributed much more too total genetic divergence. So, selection for divergent parent based on these four characters would be useful for exploitation of heterosis in Indian bean, if feasible.
