Abstract
Eleven advanced lines of bottle gourd were evaluated at the Olericulture Division, Bangladesh Research Center, Gazipur, Bangladesh during 2015-2016 for selecting the superior lines in terms of higher yield and better quality. The lines varied significantly (P<0.05) for fruit number per plant, average fruit weight, fruit yield per plant ,plant, fruit length ,length, fruit diameter and diameter and fruit yield (t/ha). The line LS151C produced the earliest fruiting (71.67 days) and maximum number of fruits per plant (12.25). The range of fruit length was 23.00 cm (LS146A1) to 43.67 cm (BARI Lau 4), while fruit diameter ranged from 10.87 cm (LS148-5) to 15.00 cm (LS139A5). The maximum fruit yield (t/ha) was recorded in the line LS151C (48.00 t/ha) which was statistically similar with LS146A1 (46.34 t/ha), LS139A1 (46.00 t/ha), LS137A5 (45.08 t/ha), LS133A4 (41.72 t/ha). Considering earliness, high yield, fruit color and acceptable fruit size and shape, out of 11, the four advanced lines, i.e., LS151C, LS146A1, LS139A1, LS137A5 were found promising.

Bottle gourd [Lagenaria siceraria (Mol.) Stand.] is a popular winter vegetable in Bangladesh
The experiment was conducted at the Olericulture Division of Horticulture Research Centre, Bangladesh Agricultural Research Institute (BARI) during the winter season of 2015-2016 with eleven advanced lines of bottle gourd and BARI Lau 3 and BARI Lau 4 as check
The performance of 11 advanced lines with two check varieties of bottle gourd is presented in Table 1 and Figure 1
Summary
Bottle gourd [Lagenaria siceraria (Mol.) Stand.] is a popular winter vegetable in Bangladesh. The climatic condition of winter in Bangladesh favours better growth and yield of bottle gourd. Bottle gourd is widely cultivated throughout the country. Availability of the advanced lines in the country is missing, to develop a high yielding variety the germplasm collection programme should be strengthen. As part of bottle gourd breeding programme, a large number of germplasm were collected and evaluated in last three years. From those findings 11 advanced lines were developed and need to be evaluated this year. The present study was undertaken to select superior lines with higher yield, better quality, and increase of seeds of the selected lines of bottle gourd
