Description The present investigation was undertaken to assess the per se performance, magnitude of heterosis and combining ability in bitter gourd during kharif and summer seasons of 2012-13 at Vegetable Research Station, Dr.Y.S.R Horticultural University, Rajendranagar, Hyderabad. The experiment was mainly contemplated to study heterosis, combining ability, gene action governing the inheritance, character association of the traits and find out the best general and specific combiners for higher yield. The genotypes under the investigation comprised of five lines (RNMC-51, RNMC-52, RNMC-53, RNMC-54 and RNMC-55) which were selected on the basis of per se performance for fruit yield from Vegetable Research Station, Rajendranagar. Ten hybrids were generated and evaluated along with five parents and two commercial checks (Maya and Palee) for the fourteen characters viz., days to first pistillate flower appearance, node of first pistillate flower appearance, days to first fruit harvest, days to last fruit harvest, fruit length (cm), fruit diameter (cm), fruit flesh thickness (mm), average fruit weight (g), number of fruits per vine, fruit yield per vine (kg), number of fruits per vine, vine length (m), internodal length (cm) and number of seeds per fruit. Combining ability analysis revealed that the ratio of GCA variance (σ2GCA) to SCA variance (σ2SCA) is of less than unity (
