Abstract


The correlation studies in thirty-six brinjal genotypes of brinjal comprising 8 parents and 28 F1 hybrids during summer season of 2006 indicated strong correlation of number of branches per plant, fruit weight and flowers per inflorescence with fruit yield. However, it exhibited weak association with days to flowering and fruits per cluster. Path analysis revealed high direct contribution of fruits per plant (0.290), fruit weight (0.275) and flowers per inflorescence (0.250) on fruit yield, while fruits per cluster (- 0.355), days to flowering (- 0.112) exhibited negative direct effect. However, indirect positive contributions of branches per plant and fruits per cluster were appreciable.
