Description 25-34
Seventeen tree tomato (Solanum betaceum Cav.) genotypes were evaluated for their morpho-biochemical diversity in
Randomized Block Design under three replications at Sikkim University, Gangtok in 2017-18. The genotypes were grouped
into five clusters and cluster I possessed highest number of genotypes (6). Highest inter-cluster distance (372237) was
recorded between clusters II & V. Intra-cluster was maximum in cluster III (28651.72) showing diversity within the cluster.
The genotype STT-110 produced maximum value for average fruit weight (81 g) and other fruit yield contributing
characters. Whereas, STT-40 produced maximum values for iron (1.86 mg/100 g), copper (0.47 mg/100 g) and manganese
(1.38 mg/100 g). Genetic parameters (PCV, GCV) along with heritability and genetic advance were highest for anthocyanin
(77.26%, 77.19%, 99% and 158.85%), flavonoid (56.91%, 56.90%, 100% and 117.22%), total phenol (52.76%, 52.72%,
99%, and 108.54%), manganese (50.87%, 49.26%, 93%, and 98.28%) and ascorbic acid (41.73%, 41.71%, 99% and
85.89%). Correlation coefficient analysis showed that polar and equatorial diameter of fruit was significantly correlated with
average fruit weight. Genotypic correlation coefficients were higher than phenotypic correlation coefficients, which indicate
the inherent association among the characters. This study highlights the potential utilization of STT-110 genotype for further
selection in future breeding programme for enhancing yield.
