Abstract/ Executive Summary:

The experiment was conducted with five hybrids and BARI Jhinga 1 as check variety at four locations of BARI which include Joydebpur, Jamalpur, Patuakhali and Phartali in summer seasons of 2014. Over the locations, fruit per plant ranged from 20 to 37 and maximum was harvested from Hybrid 1 followed by Hybrid 4 and Hybrid 6 whilst minimum from BARI Jhinga 1. The range of average fruit per plant was 136.4-167.7 g with a mean of 152.0 g over the studied locations. Combined result indicated the range of 12.47-25.95 t per ha and highest was in Hybrid 1, followed by Hybrid 4 and the lowest was in BARI Jhinga 1. Fruit infestation was not varied greatly in Joydebpur and Jamalpur location among the ridge gourd hybrids compared to the check variety and the range was 11.1-14.2. Among the test hybrids Hybrid 1 was found the best performer over locations followed by Hybrid 4 . Further trial with these selected hybrids is now continuing in the experimental field of HRC, BARI for proposing Jhinga hybrid variety.

Keywords: Ridge gourd, Yield, Adaptability

Location: Joydebpur, Jamalpur, Patuakhali and Phartali

Start Date: 00-00-2014

End Date: 00-00-2014

Program Area: Variety and Species

Commodity: Ridge gourd

Objectives:

To select suitable hybrids with high yield, better quality and wide adaptability across the country.

Methodology:

The study consisted of five hybrids of ridge gourd and BARI Jhinga 1 as control. This experiment was conducted at the experimental field of Horticultural Research Centre Joydebpur, Jamalpur, Patuakhali and Phartali location of BARI in summer seasons of 2014. Five advanced ridge gourd hybrids viz., Hybrid 1, Hybrid 3, Hybrid 4, Hybrid 6 and Hybrid 19 were evaluated against check variety as BARI Jhinga 1. Age of seedlings varied from 20-25 days in different locations. Seedlings were transplanted in the field at the appropriate age of seedling to transplant is 16-20 days. The experiment was laid out in RCB design with three replications. The unit plot size was 7.5 x 1.5 m maintaining 1.2 x 1.5 m spacing. The land was fertilized with cow dung, N, P, K, S, Zn and B @ 20000, 81, 35, 75, 18, 4.3, and 0.34 kg/ha respectively. The total amount of cow dung, P, S, Zn, B and 1/3 rd of each N and K were applied in the pit as basal dose. The rest of the N and K were applied in four equal installments at 21, 35, 55 and 75 days after transplanting. However, under balanced irrigation, the nitrogen application has increased female flower production and yield (Parikh and Chandra, 1966). The intercultural operations were done as and when needed. We measured nine quantitative characters including days to first female flower open (DFF), node order of first female flower open (NFF), marketable fruits per plant (MF/Pl), marketable yield/plant (MY/Pl), fruit length (FL), fruit diameter (FD), average fruit weight (AFW) and percentage of fruit fly infestation (% FFI). For convenience, we combined the data of all locations for four characters which include fruits/ plant, AvFtwt, yield/ha and number of fruit fly infestation for interpretation. Analysis of variance (ANOVA) and mean separation of genotypes were done using Duncan Multiple Range Test through one-way ANOVA in MSTAT-C statistical software (ver. 7, Michigan State University, East Lansing, MI) according to Gomez and Gomez (1984).

Achievement/Findings:

Combined result indicated the range of 12.47-25.95 t per ha and highest was in Hybrid 1, followed by Hybrid 4 and the lowest was in BARI Jhinga 1. Fruit infestation was not varied greatly in Joydebpur and Jamalpur location among the ridge gourd hybrids compared to the check variety and the range was 11.1-14.2. The hybrids of ridge gourd showed a better performance than the check variety BARI Jhinga 1 for marketable fruits/ plant, average fruit weight, marketable yield/ ha and percent fruit fly infestation. Among the test hybrids, Hybrid 1 was found the best performer over locations followed by Hybrid 4.
