Abstract/ Executive Summary:

The trial was conducted at the experimental field of Olericulture Division, HRC, BARI, Joydebpur during winter season of 2016-17. Five advanced lines of bottle gourd were included in the study to select superior lines with higher yield, better quality and maintain simultaneously increase the seeds of the selected lines. The lines varied significantly (P<0.05) for their response to fruit number per plant, average fruit weight (kg), fruit yield (kg/plant), fruit length (cm), fruit diameter (cm) and fruit yield (t/ha).The line LS151C produced the earliest fruiting with 85.17 days as well as the maximum number of fruits per plant (9.67). The range of fruit length was 19.70 cm (LS146 A1) - 47.37 cm (LS137 A5), while fruit diameter range was 10.45 cm (LS137 A5) - 16.89 cm (LS146 A1). The maximum fruit yield (t/ha) was recorded in the line LS151C (43.32 t/ha) which was statistically similar with LS139A1 (38.88 t/ha) and followed by LS137A5 (35.23 t/ha). Considering earliness, high yield, fruit color and acceptable fruit size, shape, 2 advanced lines viz., LS 151C, LS 139 A1 were found promising and may selected for next year RYT.

Start Date: 00-00-2016

End Date: 00-00-2017

Program Area: Variety and Species

Commodity: Bottle gourd

Objectives:

To select superior lines with earliness, higher yield and better fruit shape and colour of the selected lines of bottle gourd.

Methodology:

The experiment was conducted at the Olericulture Division of Horticulture Research Centre, Bangladesh Agricultural Research Institute (BARI), Gazipur during the winter season of 2016-17 with five advanced lines of bottle gourd viz., LS 137 A5, LS 138 B4, LS 139 A1, LS 146 A1, LS 151 C, BARI Lau 3 and BARI Lau 4 LS 137 A5, LS 138 B4, LS 139 A1, LS 146 A1 and LS 151 C, BARI Lau 3 and BARI Lau 4(as check). The seeds of these germplasm were sown on the polybag on 01October 2016. Twenty five days old seedlings were transplanted in the main field on 25October 2016. The experiment was laid out in a Randomized Complete Block design with three replications. The unit plot size was 10.0 x 2.0m maintaining 2.0 x 2.5m spacing and 0.5m drain. The land was fertilized with cowdung, N, P, K, S, B and Zn @ 10000, 80, 45, 88, 25, 1.8 and 4.5 kg/ha, respectively. Half of cowdung and all of S, Zn and B each of P and K @ 30 kg/ha will be applied during final land preparation. Rest of cowdung and P and K @ 15 kg/ha will be applied as basal in pit. Rest of N and K will be applied after 20 days of transplanting in 4 equal installments at 20 days interval starting. The intercultural operations (weeding and irrigation etc.) were done as and when necessary. Data on days to first harvest, fruit number/ plant, average fruit weight (kg), fruit yield (kg/plant), fruit length (cm), fruit diameter (cm), fruit yield (t/ha), fruit shape and fruit colour were recorded from three randomly selected plants per plot. Plot means for six quantitative characters were used for the statistical analysis using MSTAT C software.
