Abstract
The present investigation with respect to'Studies on floral biology and valuation of
seedling progenies of karonda (Carissa carandas L.)'was carried out at K. R. C. College of
Horticulture, Arabhavi, Gokak taluk of Belgaum district, Karnataka during 2011-2012.
Among all the progenies of karonda studied, the progeny ARB-6 was recorded highest
plant height (282. 33 cm), plant girth (189. 92 mm), number of primary branches (8. 00) and plant
spread (278. 33 cm N-S and 264. 33 cm E-W). The study conducted on floral biology revealed
that, the progeny ARB-4 was recorded the minimum days took for bud initiation to flowering
(15. 77 days) and had maximum number of sepals (5. 17) and stamens (5. 13). The maximum style
and stigma length (12. 70 mm and 4. 83 mm respectively) was observed in ARB-6. The maximum
per cent anthesis was observed at 5. 00 am which was ranged from 45. 33 to 58. 67. The maximum
per cent of pollen viability and germination (95. 75 and 24. 67% respectively) was noticed in
ARB-4. The variation regarding fruit characters was observed ARB-4 had Huit length (17. 28
mm), fruit girth (17. 81 mm), fruit weight (2. 75 g), number of seeds per fruit (4. 07), weight of
seeds per Huit (0. 28 g), pulp weight (2. 47 g). Variation also observed regards to fruit quality
parameters. The maximum values with respect to TSS (12. 00 ° B), ascorbic acid (37. 78 mg/toog)
total sugar (17. 77%) and reducing sugar (16. 47%) were observed in ARB-6 at mature stage,
however non reducing sugar was highest in ARB-4 (1. 39%). At ripe stage the maximum TSS
(14. 87 ° B), was observed in ARB-3. While ARB-6 had higher ascorbic acid (34. 44 mg/toog),
total sugars (19. 60%), reducing sugar (18. 70%) and non reducing sugars in ARB-2 (1. 65%).
The significantly highest yield was observed in ARB-6 (4. 58 t/ha). ARB-6, as the progeny
had favorable yield attributing characters like numbers of cluster per plant (86. 33), number of
*uits per cluster (8. 60) and number of *uits per plant (782. 33). Further the performance of ARB-
4 was on par with ARB-6, but ARB-4 showed more Huit drop. The study conducted on
organoleptic evaluation for *uits and pickles, the overall acceptability was found highest in
ARB-4 for (3. 03 fruits) and ARB-3 for (3. 85 pickles).
