Abstract: Quantitative and qualitative characters, the extent of phenotypic variability, and the relationship between characters were studied in ten F1 grape hybrids raised at IIHR, Bangalore. The study showed significant differences indicating large phenotypic variability for 11 quantitative characters. Other 10 quantitative characters expressed nonsignificant differences among the hybrids. Large phenotypic variability was also evident from variations among the hybrids with respect to PCV values of the 11 quantitative characters. Phenotypic variability occurrence was also apparent from variations among the hybrids with respect to PCV values of the other 10 quantitative characters. Occurrence of a wide phenotypic variability in experimental material was evident from the quantitative characters which expressed themselves in different combinations. It was evident from the study that the F1 grape hybrids BB x CS and BC x TS had the highest percentages of fruitful canes, BC x TS and BB x CS had the maximum number of panicles and maximum number of bunches, AES x BC and BC X TS had the maximum yields; AES x BC and CS x CLB had the maximum bunch weights: CS x CLB and AES x CLB had the highest berry weights; AK x BC and AES x BC had the highest percentage of well-developed berries; BB x CS & AK x CLB had the highest percentages of juice; BB x CS had the highest TSS percentages and BB x TS and AK x BC were earliest ripeners.
