Genetic Analysis for Yield and Its Component Traits in Bottle Gourd [lagenaria Siceraria (Mol.) Standl.]

Abstract

The present study entitled “Genetic Analysis for yield and its component traits in Bottle gourd (Lagenaria siceraria (Mol.) Standl).’’ was carried out to assess the genetic information on the nature of gene action. Heterosis, combining ability and select with the fifteen-line including standard check and four testers their forty-five F1 out of twelve quotatives characters in bottle gourd at the Horticultural Research Centre, College of Horticulture, Sardar Vallabhbhai Patel University of Agriculture and Technology, Modipuram, Meerut (250110) Uttar Pradesh, India, during summer season 2020 and 2021 in randomized complete block design (RBD) with three replications. The genotypes exhibited significant differences for all the traits under study. The variance due to line vs. tester was significantly character average fruit weight(gm), while cross vs. parent was highly significant for average fruit weight. The high heritability was recorded (>90%) from average fruit weight and fruit yield this trait hence, may be useful for effective selection. The analysis of variance for combining ability mean square due to line x tester were highly significant for days to first flower initiation, days to 50% flowering, and the lines for days to first flower initiation, days to 50% flowering, Whereas the tester for days to first flower initiation, days to 50% flowering. The genotypes IC- 394736, IC-385816, Narendra Rashmi, and Pusa Naveen exhibited significant GCA effects out of twelve characters with respect to yield (q/h) in bottle gourd. On basis of the specific combining ability effect of different crosses IC-394736 x Pusa Naveen, IC-310188 x Narendra Rashmi, Vallabh Saral x Narendra Madhuri, and IC-336820 x Narendra Madhuri were found maximum SCA effect. The F1 hybrid IC-539711 x Narendra Rashmi, IC- 539711 x Pusa Naveen and IC-394736 x Pusa Naveen showed highly significant and better parent heterosis. Thirteen SSR produce 28 alleles, an average PIC value of 0.61 and average RP value of 1.23, and genotypes IC- 398541 and genotype IC- 541393 found maximum diversity (1.00), while the minimum diversity present in genotypes Vallabh Saral and IC- 310188 x Pusa Naveen (0.33).
