Abstract
The present investigation with respect to “Morphological, physiological and yield characterization of Karonda (Carissa carandas L.) genotypes” was carried out at Regional Horticultural Research and Extension Center, Dharwad, Karnataka during 2015-16.
Seven genotypes collected were evaluated, KAR-1 recorded the highest plant height (1.41 m), plant girth (50.88 mm) and plant spread (1.79 m N-S; 1.82 m E-W). The physiological study of genotypes revealed that, the genotype KAR-1 was having the maximum leaf area (21.03 cm2) and leaf area index (0.25). Flowering characters were not much varied and almost all genotypes induced flowering in the month of January except KAR-6 and KAR-7 which have started flowering in the first week of December. All the genotypes produced white coloured flowers except KAR-3. The genotype KAR-1 produced highest number of flowers per cluster (5.44). Variation regarding the fruit characters was observed and highest fruit length (28.17 mm), fruit girth (25.23 mm), fruit weight (9.20 g), pulp weight (8.84 g) and pulp to seed ratio (24.74) were recorded in KAR-7. Variation was also observed with regard to fruit quality. The maximum values with respect to TSS (14.38 °B), ascorbic acid (34.44 mg/100g) was found in KAR-2 and reducing sugar (18.34%), non-reducing sugar (2.25%) and total sugar (20.59%) were recorded in KAR-1.
The highest yield (0.91 t/ha) and yield attributing characters viz., number of cluster per plant (36.33), number of fruits per cluster (3.77) and number of fruits per plant (137.43) were recorded in KAR-1. The yield characters were positively and significantly correlated with number of clusters per plant, number of fruits per cluster and the number of fruits per plant at both genotypic and phenotypic level. The study on organoleptic evaluation for fruits revealed highest overall acceptability in KAR-1 (2.67). The characterization of genotypes revealed that, the KAR-1 and KAR-7 were found the superior among seven genotypes with respect to morphological, physiological, yield and quality parameters.
