Abstract: Bitter gourd (Momordica charantia L.) is one of the most popular vegetables in India. The natural flowering behavior of bitter gourd to produce a greater number of pistillate flowers than staminate flowers is the major limitation for the yield improvement. Fifty-three genotypes of bitter gourd were evaluated for the sex phenology, yield and yield contributing characters. The wild genotype AC-16/25 can be marked as an early variety based on sex phenology. The number of pistillate flowers and number of fruits per plant was found to be the highest in JJNS-15/65. Even though, a greater number of pistillate flowers and fruits per plant were produced by the wild genotypes, the fruit yield per plant was found to be the highest in cultivated charantia types. A significant positive correlation was observed between yield per plant and other yield contributing characters viz., fruit weight, fruit length, fruit width and flesh thickness.
Keywords: Bitter gourd, correlation, pistillate, sex phenology
