- Abstract
Background: In any crop improvement, hybridization among selected/chosen parents is the first foremost important step. Diversity among the genotypes is the basis for choice of parents. It requires knowledge on genetic nature of traits and such information will allow plant breeders to predict the response to selection in breeding programmes. Pole bean, a self pollinated crop, is morphologically diversity is high with distinguishable qualitative and variable quantitative traits. Methods: A field experiment was carried out at Horticultural Research Station, Tamil Nadu Agricultural University, Thadiyankudisai with 31 pole beans genotypes which were evaluated for nine characters. The experiment was laid out in a randomized block design and replicated thrice. Result: Analysis of variance revealed the significant difference among genotypes for all the studied characters. Per se performance of the 31 genotypes showed that the genotype Pallathuvaikal local performed as the best genotype for number of pods per plant, pod weight, pod yield per plant, pod yield per plot and pod yield per hectare. The traits pod length, pod girth, number of pods per plant, pod weight and yield per plant had exhibited high to medium PCV and GCV. The results of heritability and genetic advance showed that the traits pod length, number of pods per plant, pod weight, yield per plant, yield per plot and yield per hectare had exhibited high degree of heritability and genetic advance.
