Correlation Co-efficient and Path Analysis in Okra Abelmoschus esculentus L. Moench

The experiment was conducted at Vegetable Research Farm, Department of Horticulture, Allahabad Agricultural Institute-Deemed University, Allahabad during the year 2006-2007. Correlation coefficient analysis revealed that yield showed significant positive correlation with plant height and yield at both genotypic and phenotypic level, suggesting that selection of these characters may be useful for the development of ideal plant type of okra for the Allahabad agro-climatic condition. The correlation co-efficient and path co-efficient of various characters was significant in plant height, yield/ha, yield/plant, Vitamin C, number of leaf/plant, number of fruits per plant. The magnitude of phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV) for all the character. Minimum variation between PCV and GCV was recorded for the character days to 50 % flowering, followed by plant height, yield/ha, yield/plant, Vitamin C, number of leaf/plant, number of fruits per plant and maximum variation in % plant affected by YVMV. Lower variation between PCV and GCV revealed greater stability of the character against environment fluctuation.
