Genetic Variability in Mango Clones of Langra cv. for Physical-bio Chemical Parameters at Kymore Plateau and Satpura Hills of Madhya Pradesh, India

Abstract

The present study was carried out to assess the genetic variability, heritability and genetic advance for different characters in 40 clones of mango. The study was conducted at Fruit Research Station (Farm), Imalia for evaluating the variability of Langra clones in Randomized block design. All the characters showed very small difference between genotypic coefficient of variation (GCV) and respective phenotypic coefficient of variation (PCV), indicated that all the characters were least affected by environment. The high phenotypic coefficient of variation and genotypic coefficient of variation were observed for pulp %, peel %, stone %, pulp : stone ratio, pulp : peel ratio, fiber %, density of lenticels, fruit weight kg, acidity %, reducing sugar % in the both years.  High heritability coupled with genetic advance were observed for all characters studies indicating these characters are governed by additive gene action and phenotypic selection may be more fruitful. Hence, direct selection may be followed for the improvement of mango for these characters.
