GENETIC VARIABILITY, HERITABILITY AND GENETIC ADVANCE IN GARLIC GENOTYPES
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 54
Abstract
Genetic variability studies among the 131 garlic genotypes using twelve morpho-agronomic traits were carried out at SVPUAT, Meerut, during Rabi-2014. ANOVA showed significant genetic variation (p<0.05) for all traits indicated sufficient variability in germplasm. Phenotypic coefficient of variation (PCV) was higher in comparison to the genotypic coefficient of variation (GCV) and high estimates of the GCV and PCV were observed for plant height, bulb weight per plant, leaf length, number of cloves per bulb and pseudostem height. Furthermore, high heritability was obtained for all traits (>60%) and High heritability coupled with moderate genetic advance was recorded for clove weight, bulb weight per plant, pseudostem height, polar diameter of bulb, equatorial diameter of bulb and number of cloves per bulb. The genotypes viz., PG-20, K-1, GHC-1, TG-1, CFG-3,G-50 are noticed with good export potential and can be utilized for improvement of garlic germplasm.
