The study was carried out to find out the extent of variability among the khirni genotypes. All the characters varied significantly. The fruit ripening time varied from second week of March to fourth week of May. Number of fruits per fascicle ranged from 1.67 to 10.33.Fruit weight varied from 3.33g to 14.85g. Fruit length found in between 2.23cm (MGK31) to 3.25cm (MGK16). Fruit diameter varied from 0.86cm to 2.11 cm. Pulp: seed ratio fall in between 1.57cm to 10.64. Fruit yield per side of tree varied from 4.40kg to 10.90kg. TSS varied from 19.00 °Brix to 31°Brix. Vitamin C ranged from 15.20 mg/100g to 25.70 mg/100g and carotene content varied from 3.57 mg/100g to 6.47 mg/100g. Seed weight and germination percentage ranged 0.74g to 2.57g and 56% to 88.33% respectively. The Phenotypic coefficient of variation was higher than Genotypic of variation for all the characters studied indicates effect of environment in expression of characters. High heritability combined with high genetic advance was recorded for pulp: seed ratio, fruit weight, number of fruits per fascicle indicating these characters can be improved by selection.
