Abstract
A field experiment entitled ‘‘Evaluation of Capegooseberry (Physalis peruviana L.) Under Humid Agro-climatic condition of Jhalawar’’ was conducted at the Protected Cultivation Unit, College of Horticulture and Forestry, Jhalawar during 2015-2016. The experiment consisted of 10 genotypes viz., Amb. Sel.-1, Amb. Sel.-2, Amb. Sel.-3, Amb. Sel.-4, Amb. Sel.-5, Amb. Sel.-6, Amb. Sel.-7, Selection-7, Selection-9 and Selection-21 and was laid out in randomized block design with three replications. Among all genotypes of capegooseberry ‘Selection-7’ was found maximum yielder followed by Selection-9 and Selection-21. Further these three genotypes were found having maximum fruit diameter-vertical as well as horizontal, fruit weight, number of fruits per plant and fruit set per cent. The ‘Amb. Sel.-3’ was found superior in respect to TSS, total sugar, juice per cent, vitamin-C, sensory score and carotene. Analysis of variance indicated presence of considerable variability for all characters. High GCV and PCV were observed for plant spread E-W followed by plant spread N-S, number of nodes per plant, leaf breadth, fruit diameter-vertical, horizontal, fruit weight, number of fruits per plant, fruit yield per plant, estimated yield, TSS and TSS/Acid ratio. Therefore, these characters can aid in selection programme. These characters may be considered by breeder for breeding programme. High heritability with high values of genetic advance was observed for plant spread (N-S), leaf breadth, leaf perimeter, days taken to first flower initiation, fruit diameter horizontal (mm), fruit weight, fruit yield per plant, estimated yield, total soluble solids and TSS/acid ratio. The result from character association indicated that fruit yield had highly significant positive correlation with plant spread E-W, plant spread N-S, total chlorophyll content of leaves, number of nodes per plant, number of branches per plant, fruit diameter-vertical, horizontal, fruit weight, number of fruits per plant, estimated yield and titratable acidity. Path coefficient analysis revealed that characters viz., days taken to first flower initiation, plant spread E-W, leaf perimeter, estimated yield, no of nodes per plant, leaf breadth, number of fruit per plant, fruit diameter-vertical, plant height, TSS/Acid ratio, carotene, total chlorophyll content of leaves, sensory score, juice, root : shoot ratio, fruit weight, vitamin-C had high positive direct effect on fruit yield. Result obtained from the present study based on variability parameters, correlation and path analysis revealed that selection programme based on plant spread E-W, spread N-S, total chlorophyll content of leaves, no of nodes per plant, no of branches per plant, days taken to first flower initiation, fruit diameter-vertical, horizontal, fruit weight, number of fruits per plant, total soluble solids, TSS/acid ratio, carotene, sensory score, juice content and vitamin-C proved positive effect on yield in Capegooseberry. Based on overall study of various parameters of all 10 genotypes, it appeared that genotype Selection-7 was found maximum yielder (2.386 kg/plant) but organoleptic score wise rated lesser (5.83). However, Amb. Sel.-3 had less yield (408.03g/plant) but quality wise (Organoleptic score 8.25) it has superior. Hence, it can be considered for cultivation.
