Abstract
Correlation analysis were studied using parents (TCR-1674, SB-2, 440-10-1, VROB-178, TCR-1693, VRO-3 and VRO-6), their F1s. Observations were recorded on fourteen characters. Fruit yield per plant had significant and positive association with traits like plant height, number of fruits per plant, fruit length, fruit girth, average fruit weight and number of seeds per fruit at both phenotypic and genotypic levels indicating all these traits should be considered collectively for improving the yield in okra.
Okra (Abelomoschus esculentus L. Moench) commonly known as lady’s finger belongs to the family Malvaceae. Tender okra fruits are used as vegetable in countries viz. India, Brazil and West Africa. It’s available in dehydrated and canned forms. The sun-dried (Africa, India), frozen and sterilized (USA) fruits are other important market products. Okra fruit contains 90% water, 3% dietary fibre, 7% carbohydrates, 2% protein, good quantities of minerals, vitamin C and A and moderate contents of thiamin, folate and magnesium (Chopra et al., 1956). A wide range of variation in quantitative characters provides the basis for selection in plant breeding programmes. The knowledge of association among the characters is useful to the breeder for improving the efficiency of selection. Correlation coefficient analysis measures the mutual relationship between plant characters and determines the component characters on which selection can be made for genetic improvement of yield.
