 ABSTRACT

An experiment was carried out with 21 red tamarind clones planted in a spacing of 5×5 meters with randomized block design at IFGTB – Field Research Station, Kurumpapatti, Salem, Tamil Nadu. The red tamarind clones were evaluated to determine variability parameters like genotypic coefficient of variation, phenotypic coefficient of variation, heritability and genetic advance as per cent of mean for fifteen quantitative and qualitative traits. The high genotypic variation was recorded in length of inflorescence, number of flowers/inflorescence, fruit length, fruit breath, fruit weight, pulp weight, seed weight and fruit yield/tree. All the characters registered high phenotypic coefficient of variation then the genotypic coefficient of variation. High phenotypic coefficient of variation, genotypic coefficient of variation, heritability coupled with high genetic advance as per cent of mean was registered in length of inflorescence, number of flowers/inflorescence, fruit yield/tree, fruit length, fruit breadth, fruit weight, pulp weight and seed weight of red tamarind. It is due to additive gene effect and considering these characters would be more effective for selection of elite clones in tamarind improvement programme.

Key words: Red Tamarind clones, Genetic variability, Yield, Quality parameters.
