Heterosis for fruit yield and its components in bottle gourd [Lagenaria siceraria (Mol.) Standl.]

Author(s): Balat JR, Patel JB, Delvadiya IR and Joshiyara NS
Abstract: The present investigation was carried out in four different seasons with aim to assess the heterobeltosis and standard heterosis in bottle gourd. The experimental materials comprised of 45 entries includes nine parents (ABG 1, Punjab Long, NDBG 132, Arka Bahar, Pusa Naveen, DBG 5, Samrat, DBG 6 and Santosh), their 36 F1s developed through half diallel mating design excluding reciprocals. Parent ABG 1 was used as a standard check. The materials were evaluated in a Randomized Block Design with three replications over four environments during kharif 2018 and summer 2019 at Sagdividi Farm, Department of Seed Science and Technology, College of Agriculture, Junagadh Agricultural University, Junagadh. Four environments were created by two seasons with two dates of sowing in each season. The analysis of variance pooled over environments revealed significant differences among environments, genotypes, parents and hybrids for all the traits studied except for fruit length due to environments. On pooled basis, seven hybrids over better parent and three hybrids over standard check exhibited significant and positive heterosis. Based on magnitude of significant and desirable heterobeltiosis, Pusa Naveen × Samrat (55.03 %), Punjab Long × DBG 5 (54.30 %), Samrat × DBG 6 (44.41 %), Punjab Long × Pusa Naveen (42.26 %) and ABG 1 × Arka Bahar (40.47 %) in pooled over environments were the best five significant and desirable heterobeltiotic cross combinations. Based on magnitude of significant and desirable standard heterosis, the best five crosses were ABG 1 × Arka Bahar (43.68 %), Arka Bahar × Pusa Naveen (31.36 %), NDBG 132 × Arka Bahar (30.38 %), Punjab Long × NDBG 132 (29.72 %) and NDBG 132 × Samrat (28.24 %) in E1; ABG 1 × Arka Bahar (38.84 %), Arka Bahar × Pusa Naveen (32.49 %), Punjab Long × NDBG 132 (32.12 %), NDBG 132 × Arka Bahar (29.40 %) and ABG 1 × NDBG 132 (28.31 %) in E2; ABG 1 × Arka Bahar (55.46 %), Punjab Long × DBG 5 (41.05 %), Punjab Long × NDBG 132 (38.65 %), Punjab Long × Pusa Naveen (33.62 %) and ABG 1 × NDBG 132 (28.38 %) in E3; and Pusa Naveen × Samrat (46.43 %), NDBG 132 × Arka Bahar (41.84 %), NDBG 132 × Pusa Naveen (36.48 %), ABG 1 × Arka Bahar (36.22 %) and NDBG 132 × Santosh (35.97 %) in E4 environment. Across the environments, ABG 1 × Arka Bahar (43.82 %), Punjab Long × NDBG 132 (30.28 %) and NDBG 132 × Arka Bahar (27.69 %) noted significant and desirable standard heterosis.
