Abstract: The study on changes in fruit growth and development on eight ber cultivars viz., Chhuhara, Chinese, Kalagola, Nazuk, Sanaur-2, Sanaur-4, Umran and ZG-2 was conducted at Horticulture Research Centre, Patharchatta, G. B. Pant University of Agriculture & Technology, Pantnagar, U.S. Nagar, Uttarakhand, India during the season of 2017-18 and 2018-19. The experiment was laid out in two factors Randomized Block Design (RBD) with three replications. Sampling dates and cultivars were considered as the treatments. There were 11 sampling dates commences at 28 days after full bloom (DAFB) to 168 DAFB and observations were taken at biweekly interval. Findings of the study showed a characteristic double sigmoid growth pattern in most of the cultivars which could be divided into four growth phases viz., initial rapid growth of six weeks; lag phase or slow growth of six weeks for seed development; gradual increase in growth for next 6 weeks and later accelerated fruit growth during next four weeks before fruit enter in to its optimum maturity phase. However, these phases varied with the cultivars. TSS increased significantly with advancement of growth and development period and followed the trend of double sigmoid curve. A significant increase in TSS content was witnessed up to 154 DAFB in most of cultivars. The percent titratable acidity showed a downward trend among all cultivars from a maximum of 0.49% at first sampling date to a minimum of 0.07% at last sampling date.
