(115.13mg), DBTG-9 (108.43mg), DBTG-7 (100.67mg) and DBTG-4 (92.15mg). The genotype, DBTG-8 recorded maximum total carotenoids content (3.2mg) followed by DBTG-9 (3.0mg), DBTG-101 (2.9mg), DBTG-6 (2.8mg), DBTG-4 (2.7mg) and DBTG-2 (2.6mg). Among the above mentioned genotypes, DBTG-3, DBTG-8, DBTG-6 and DBTG-101 were small fruited genotypes ((Momordica charantia var. muricata) those were found superior with respect to nutritional property. Among the small-fruited genotypes, DBTG-8 was found to be highly promising for its better nutritional qualities long with higher fruit yield. In large fruited group ((Momordica charantia var. charantia), the genotype DBTG-4 was observed to be most promising with respect to fruit yield, fruit length, fruit diameter, flesh thickness and high ascorbic acid and total carotenoid content. It was very interesting to note that some of the whitefruited genotypes like, Pusa Do Mausami (White), Preethi and DBTG-10 contain very less amount of total carotenoids (less than 0.5mg/100g). It might be due to the fact that, these genotypes contain less chlorophyll, which may have contributed to less carotenoid synthesis (4). It is concluded that genotypes with higher ascorbic acid and carotenoid content may be utilized for quality improvement of bitter gourd. These materials are now being utilized for the genetic study and the inbreds are maintained in the Institute. Literature Cited: 1. Albrecht, J.A.1993. Ascorbic acid retention in lettuce. J.
