Variability for bunch and berry characteristics in seeded and seedless grape genotypes evaluated under subtropical condition in India

Forty-seven grape genotypes were evaluated under subtropical climatic conditions of Delhi, India from 2014-16. All the genotypes were mainly grouped under two categories i.e., seeded and seedless. Each category was further categorized in to white and coloured. These genotypes were consisted of mainly Vitis vinifera L., except Vitis parviflora genotype. The data were recorded for bunch and berry quality traits, important pomological traits usually taken into consideration for evaluation of grapes. Standard procedures were adopted for recording the observation. Results indicated that, greater variability existed among all the genotypes studied. The mean values among the different categories indicated that, larger size of the bunch in terms of weight and length was recorded in seedless white. Whereas, the maximum size of the berry in terms of weight was recorded in seedless white genotypes followed by seeded white, coloured seeded and minimum was recorded in seedless coloured genotypes. However, it is not the correct indicate of the traits but was mainly genotype dependent.
