| dc.description.abstract | An investigation was taken up to assess variability, diversity and combining ability in cucumber during the period from October, 2004 to March, 2006 at Horticulture farm of Agricultural College, Bheemarayanagudi, Gulbarga. To assess genetic variability and diversity 45 genotypes were evaluated. Out of 20 characters studied genotypic and phenotypic variation were high for marketable fruits per vine. High heritability coupled with genetic advance over mean were recorded for total fruit yield per vine. Fruit yield had positive and highly significant association phenotypically and genotypically with vine length, intemodal length, number of branches per vine, number of nodes per vine, fruit length, fruit diameter, average fruit weight, number of marketable fruits per vine and total number of fruits per vine. Average fruit weight had positive and direct genotjrpic and phenotypic effect on fruit yield per vine. Using estimated values 45 genotypes were grouped into 8 clusters. The highest inter cluster distance was noticed between IV and V clusters. The intra cluster distance was highest in Vll cluster. To determine heterosis and combining ability five lines and seven testers were selected and subjected to line x tester analysis. BGDL X Hot Season, BGDL x White Long, BGDL x Hyderabad cucumber were superior performers owing to the high total fruit yield per vine and total number of fruits per vine. Among 35 hybrids maximum positive heterosis over mid and better parent were noticed in the hybrids BGDL x Hot Season and BGDL x White Long respectively, for total fruit yield per vine. Variance due to SCA was higher than GCA for most of the characters studied indicating involvement of dominant gene action than additive gene action. The hybrids GBGL x Hyderabad Cucumber and BGDL x Hyderabad Cucumber were most stable for yield and well adopted to all three environments. | en_US |
