Morphological Characterization of Different Jamun (Syzigium cuminii Skeels) Genotypes

Jamun (Syzygium cumini Skeels) is an important underutilized tropical fruit crop of India possessing high nutraceutical value belongs to the family Myrtaceae. Totally, fifteen jamun genotypes were studied for morphological and for flower, fruit, seed, biochemical and physiological characters during 2019-2020 at Regional Horticultural Research and Extension centre, University of Horticultural Sciences Campus, Gandhi Krishi Vignana Kendra, Bengaluru. A significant differences were observed in morphological and physico-chemical characteristics among the various genotypes of jamun. The genotype GKVK-1 recorded the highest tree height (718 cm), highest east-west (653 cm) as well as north- south (612 cm) canopy spread whereas lowest tree was height recorded in the genotype Mysuru (408 cm), the genotype Bahadoli showed lowest canopy spread. The genotype GKVK-1 recorded highest leaf length (16.24 cm) followed by the genotype GKVK-2 (13.20 cm) as well as the leaf breadth of 6.64 cm whereas the lowest leaf length was noticed in the genotype Kallahalli (10.80 cm). The petiole length of the genotype Seedless recorded the highest value of 3.06 cm. The genotype Dhoopdal recorded the highestintermodal length. Cluster analysis revealed that genotypes in the cluster IV (NO. -58, GKVK-2) were more vigorous and cluster III (Mysuru, Seedless) were least vigorous. Among the physiological parameters highest stomatal frequency was found in the genotype No. 20 (60.80), relative water content was found in the genotype Bahdoli (88.33 %), total chlorophyll content was found in genotypes Mysuru and seedless (1.09 mg/cm2).
