| dc.description.abstract | The present investigation entitled “Assessment of Genetic Variability and Correlation Studies in Garlic (Allium sativum L.)” were carried out at the Experimental farm of College of Horticulture and Forestry, Neri, Hamirpur (HP) during the Rabi season of 2019 -2020. The experimental material for the studies was comprised of eighteen genotypes collected from different sources (NHRDF Karnal, KVK Kandaghat(UHF, Nauni), CSKHPKV, Palampur and Local places). These genotypes were sown in Randomized Block Design in three replications to estimate the genetic variability and association analysis (correlation and path coefficient). Analysis of variance indicated the presence of considerable amount of variability among all the genotypes for all the traits under study.on the basis of mean performance Khandaghat Selection was found to be best performing genotype with highest bulb yield per plot (3.97 kg), bulb yield per hectare (176.44 q/ha), clove weight (3.51 g), dry matter content (44.43%) and minimum disease severity of purple blotch (7.33%) followed by GHC-1. Moderate PCV and GCV existed for leaf length, bulb yield (q/ha) , clove weight , number of cloves per bulb , neck thickness , bulb size index , TSS , plant height , number of leaves per plant and disease severity . High estimates of heritability along with high value of genetic advance were observed for bulb yield (kg/plot), dry matter content , days to harvest and bulb diameter which suggested that these traits can aid in selection programme and can also be improved by direct selection. Further character association revealed that bulb yield (kg/ha) showed positive and significant association with plant height, leaf length, number of leaves per plant, bulb size index, number of cloves per bulb , clove weight, dry matter content and bulb yield per plot which indicated that these traits have their significant contribution towards total yield. Path coefficient analysis revealed that clove weight, number of cloves per bulb, number of leaves per plant, bulb size index, plant height and bulb yield per plot had direct positive effect on bulb yield per hectare indicating that selection based on these traits can help in improving the yield of garlic. On the basis of above mentioned studies genotype Kandaghat Selection was found higher yielder followed by GHC-1 and Garlic LC-4 surpassing the check Agrifound Parvati (G-313). So, these genotypes may be utilized for further breeding programme in garlic. | en_US |
