Abstract:
In spite of being in cultivation since ancient times and wide germplasm availability, conscious evaluation and exploitation of germplasm in heterosis breeding has not been attended to until recently. Therefore, the present investigation was caried out to assess the performance of eight parents with their twenty-eight cross combinations and two checks (Pusa Naveen and Arka Bahar) conducted at Vegetable Research Centre, Department of Vegetable Science, G. B. Pant University of Agriculture & Technology, Pantnagar, Uttarakhand during the kharif season of 2021. Investigation results revealed that the mean sum of squares (MSS) due to genotypes were found to be highly significant for all the characters under studied where, the means data of yield (kg plant^-1 and q ha^-1) revealed the maximum yield was observed in hybrids P₃ × P₈ (12.27 kg plant^-1). The estimates of coefficients of variation revealed that magnitude of phenotypic coefficients of variation (PCV) was observe higher than the genotypic coefficient of variation (GCV) for all the characters. On the other hand, mostly all character showed high heritability coupled with high genetic advance where, fruit yield and its attributing characters (fruit length, fruit grith, number of fruits plant^-1 and average fruit weight) had shown high heritability coupled with high genetic advance under the study which indicated that there are chances of getting improvement by practising selection.
