Correlation and path coefficient analysis of yield and yield attributed characters in Brinjal (Solanum melongena L.)

Abstract

The experiment was conducted to evaluate yield and yield attributed characters of 33 brinjal genotypes at College of Horticulture, SKLTSHU, Hyderabad during Kharif, 2019 and was laid out in Randomized Block Design with two replications. The correlation coefficient analysis shown fruit yield per plant exhibited maximum positive association with number of fruits per plant (0.8997), marketable yield per plant (0.6300), number of branches per plant (0.2293), fruit diameter (0.1339), fruit weight (0.1233), days to first flowering (0.1176). Path coefficient analysis shown maximum positive direct effect on fruit yield per plant through days to first fruit harvest (1.1811G), number of fruits per plant (0.8929G, 0.9813P), fruit weight (0.7588G, 0.3485P), days to last fruit harvest (0.3340P), days to first flowering (0.2431G) and number of branches per plant (0.2278G). Hence, direct selection can be done by considering these traits as the main criteria to overcome indirect effects for development of high-yielding brinjal varieties.
