Abstract:
The experiment was carried out during the period from April to August 2012 at
the Regional Horticulture Research Station, Narsingdi. In this experiment nine
collected lines and one local germplasm of ridge gourd were used as test crop.
The single factor experiment was laid out in a Randomized Complete Block
Design with three replications. The highest weight of individual fruit (137.55 g)
was obtained in LA-211 and the lowest weight (73.55 g) in LA-208. The highest
fruit yield (22.41 t/ha) was found in LA-211 and the lowest yield (8.04 t/ha) in
LA-210. For 10 traits phenotypic variation was higher than the genotypic variance
with moderate to high heritability and moderate genetic advance and in
percentage of mean. Positive significant association was observed for fruit
yield/ha in respect of individual fruit weight (0.526), number of fruits/plant
(0.711), fruit yield/plant (0.968) and fruit yield/hectare (1.00), while significant
negative association was observed for days required to 1
st
harvest (-0.390). Path
analysis revealed that all the parameter showed positive direct effect except days
to 1
st
harvest and weight of 100 seeds. On the basis of performance study, the
genotype LA-211 was found to be most promising in order to develop a ridge
gourd variety.
