Abstract:
An appreciable level of variation within crop varieties is essential to initiate and sustain crop improvement using plant breeding methods. A study was conducted to evaluate the Local germplasm lines of bitter gourd for yield and yield attributing traits between June 2019 to September 2019. The twenty-five cultivars collected from different agro-climatic regions of India constituted the treatment, which was lied out in a Randomized Complete Block Design with two replicates. Eighteen yield and yield attributing characters were studies and analysis of variance revealed that there were significant differences among the genotypes studied for all the characters. Among the twenty-five germplasm Ludhiana Local was identified as the best genotypes as it recorded higher yield per plant followed by Preethi, Kerala Local, Vizag Local and Faizabad Local. Maximum phenotypic and genotypic coefficient of variation (PCV and GCV) was recorded for total yield per plant, number of fruits per plant, average fruit weight, fruit length. High heritability was observed for all the characters. High estimates of heritability linked with a high genetic advance as a percentage of the mean were recorded for sex ratio, internodal length, leaf area, average fruit weight, fruit length, number of fruits per plant, fruit diameter. These results are suggestive that the cultivars evaluated in this study are good candidates on which improvement activates can be initiated the incorporation of high grain yield traits would also have a long run advantage.
