Nine diverse genotypes of bitter gourd (Momordica charantia L.) were crossed during summer season of 2015 in diallel design (excluding reciprocals).The resultant 36 hybrids along with the parents were evaluated in randomized block design with three replications during Kharif 2015 at Horticulture farm, S.K.N. College of Agriculture, Jobner. Each parents/F1 were sown in furrow maintaining 2.25m x 0.75m spacing. The analysis of variance for experimental design revealed the existence of adequate genetic variability in experimental material for all traits under study.

Bitter gourd (Momordica charantia L.) is a monoecious and cross pollinated crop with a high degree of variability, having enormous chances of either exploiting hybrid vigour or selection in segregating population. Information on different qualitative and quantitative characters with respect to genetic variability, heritability and genetic advance are of great interest to plant breeders as they play a vital role in the development of a successful crop improvement programme.

The present investigation was carried out involving thirty hybrids which were derived by crossing ten lines with three testers. These hybrids were evaluated along with their parents in randomized block design (RBD) with three replications. The recorded data was subjected to Line × Tester analysis. The analysis of variance for combining ability revealed that the mean sum of squares due to parents and hybrids were highly significant for almost all the characters except for days required to 50% pistillate flowering, vine length, number of primary branches per plant and internodal length.

Eight parental lines including one gynoecious line PDMGy-201 (Gy-23) and their 28 F1 hybrids obtained from half diallel analysis were used to estimate the extent of heterosis for earliness, yield and its contributing traits in bitter gourd. The F1 hybrids developed using gynoecious line as one parents were found to be superior in performance over mid and standard parents for several earliness and yield characters.

The experiment was conducted at AICRP on vegetable crops, OUAT, Bhubaneswar, India to study the performance of twenty eight bitter gourd hybrids along with eight genetically diverse parents. The analysis of variance for experimental design revealed that the differences among the mean square due to treatments were found highly significant for all the traits. Further variance due to parents and hybrids (within group) were also found significant for all the studied characters. Difference due to parents Vs hybrids were also found highly significant for all characters studied.

Bitter gourd (Momordica charantia L.) is popular vegetable because of its rich nutritive value, high productivity and easy package of practices which respond favourably to application of different soil organic amendments like vermicompost. In this experiment it was designed to evaluate the effect of different combinations of organic (vermicompost) and inorganic (NPK) source of nutrients on growth, yield and quality of bitter gourd. The application of vermicompost @ 4.68 t ha-1 recorded 3.99 kg/ fruits per vine with an average fruit weight of 62.18 g/fruit.

An experiment was conducted at the poly house, Dept. of Horticulture, College of Agriculture, RVSKVV, Indore, M. P. during the year 2015- 16.The experimental material was comprised of ten varieties grown in Randomized Block Design with three replications, to record morphological, phonological, yield and its attributing traits. On the basis of the result it was found that the hybrid variety Jhalri Priya 5 showed superior result under polyhouse condition and economically viable for polyhouse growers.

Seven genetically dissimilar parental lines i.e., Pusa Ausadhi, Jhalri, Kathi No.1, Pusa Rasdar, BRBT Local, Konkan Tara, Solan Hara were crossed in a diallel (half) pattern to get 21 hybrid to investigate extent of heterosis fruit yield and quality traits in bitter gourd at vegetable research farm, Bihar agricultural university, Bihar during summer season 2016 and 2017. The cross combination Pusa Ausadhi X BRBT Local exhibited maximum heterosis over standard check for yield and yield attributing trait like number of primary branch, vine length, fruit length and fruit weight.

The present experiment was formulated on vegetable research farm, Bihar Agricultural University, Sabour to study the per se performance of 21 hybrids with seven dissimilar parents. The ANOVA for experimental design expressed that the treatment variance were highly significant for all the quantitative and qualitative traits. Fruit yield is the ultimate character which shows the utility of a genotype in farmer’s field. As per the present findings, the parents Pusa Ausadhi, followed by BRBT Local and Kathi No.1 were the most promising parental line.
