Abstract
Existing low variability unexploitation and lack of awareness, this crop is not popularised among the growers. However, to some extent variation is seen in the genotypes with respect to morphological, physico–chemical parameters and also in productivity. The present research was carried at department of Fruit Science, KRCCHA, through survey of eighty six genotypes from selected districts of Karnataka viz., Vijaypura, Belgavi, Haveri, Shivamogga, Davangere, Chitradurga and Tumukur during the fruiting season of 2018-19. Among 86 genotypes surveyed, 49 were small, 27 were medium and 10 were large type. The tree girth ranged from 18.00 cm to 230 cm with an average tree girth of 103.47 cm, while, 40 genotypes are spreading, 35 genotypes are semi spreading and 11 genotypes were erect type of growth habit and 52 genotypes shown oval type of canopy and 34 genotypes exhibit round shape of canopy. The age of the plants varied between 13 to 70 years with yield potentiality of the plants varied from 6.84 to 563.04 kg/plant. The fruit weight ranges between 79.6 g to 424 g, the number of fruits per plant varied from 50 to 2300 per plant, fruit length ranges between 5.21 to 8.68 cm, fruit breadth ranges from 5.27 to 8.95 cm, fruit size varies from 29.94 to 68.30 cm², fruit volume ranges from 46 ml to 424 ml, while 11 genotypes were found to produce oval shaped fruits, 19 genotypes were found to produce oblong shaped fruits and 49 genotypes produced round shaped fruits and the almost all were found to posses greyish white colored fruits. The pulp weight (42.2 g to 359 g,) pulp percentage (55.28 to 90.96,) rind weight (22.2 g to 85.2 g,) rind thickness (0.33 to 0.47 cm,) TSS (12.37 to 14.14 °Brix,) acidity (2.81% to 3.83%) while, total sugars (5.94 to 6.88%) and ascorbic content (3.85 to 4.09 mg/100g) was recorded in different selection surveyed and finally 5 elite types were identified based on yield, quality and consumer acceptance.
