Estimation of Response to Selection in Chilli (Capsicum annuum L.)

This experiment was conducted at Main Experiment Station of Department of Vegetable Science, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during Rabi 2019-20. The objective of the experiment was to estimate the correlation coefficient among yield and yield attributing traits in available genotypes of chilli. There were 35 genotypes and one check (KA-2) used in study as an experimental material.

The investigation was carried out in Randomized Completely Block Design with 3 replications. Observations were noted on 10 traits viz. days to 50% flowering, number of primary branches per plant, plant height (cm), and days to maturity (Red Ripe Stage), average fruit weight (g), fruit length (cm), days to maturity (Mature Green Stage), fruit diameter (mm), and fruit yield per plant. Fruit yield/plant was significantly and positively associated with average fruit weight and number of fruits per plant while primary branch per plant, fruit length and plant height showed negative and significant correlation with fruit yield per plant. Thus, selection for these parameters with positive correlation would be effective for yield improvement in chilli.
