Heritability (narrow sense) and genetic advance of for growth, yield and quality traits in bottle gourd [Lagenaria siceraria (Mol.) Standl.]

Author(s): Deepak Kumar Gautam and GC Yadav
Abstract: Carried out in two different seasons with aims to assess the extent of heritability and genetic advance involving 10 parents namely, NDBG-49-2 (P1), N. Rashmi (P2), N. Prabha (P3), N. Pooja (P4), Pusa Naveen (P5), Pb. Komal (P6), NDBG S-1 (P7), PBOG-3 (P8), NDBG-11 (P9) and Faizabadi Local (P10) at MES, Vegetable Science, NDUA.&T, Narendra Nagar (Kumarganj), Faizabad (U.P.) India during kharif 2015 (E1) and Rabi, 2015-16 (E2). The experiments were laid out in RBD with three replications having each experimental unit of single row with spacing of 3.0 m × 0.5 m. The observations were recorded on parents and F1’s for eighteen quantitative traits including six quality traits viz., days to first staminate flower anthesis, days to first pistillate flower anthesis, node number to first staminate flower, node number to first pistillate flower appearance, days to first fruit harvest, vine length (m), number of primary branches per plant, fruit length (cm), fruit circumference (cm), fruit weight (kg), number of fruits per plant, fruit yield per plant (kg), total soluble solids (°B), ascorbic acid (mg/100 g fresh fruit), reducing sugar (%), non-reducing sugar (%), total sugars (%) and dry matter content in fruit (%).The higher values of heritability (h2n) estimates (> 30) were observed only for fruit length (52.20%, 37.50% and 35.17%) and fruit circumference (61.50%, 33.50% and 31.50%) during both the seasons and pooled. High genetic advance in per cent of mean were estimated for four traits, viz. number of fruit per plant (32.58%, 42.73% and 21.33%), fruit yield per plant (24.60%, 32.40% and 25.82%), reducing sugars (22.01%, 25.10% and 22.42%) and non- reducing sugar (27%, 38.96% and 28.01%) during both the seasons and pooled.
