Abstract

Genetic variability, correlation and direct and indirect effects of biochemical parameters associated with crop
duration was studied in 15 genetically diverse genotypes of grape [Vitis vinifera L.) during 1991-94. The genotypes
showed significant variation for total phenols, total sugars, organic acids, total free amino acids, soluble protein, total
nitrogen peroxidases and polyphenol oxidase activity (ali in leaves) and total duration of the crop (from pruning to
berry ripening). It indicated that the magnitude of variability for all the parameters are very high. The total free amino
acids in the leaves was found closely correlated with duration of crop growth and contributed significantly to the
variation in the duration of crop growth. Heritability and genetic advance were high for total free amino acids in the
leaves.
