Abstract
The present study evaluated the performance of fifteen pot anthurium genotypes based on vegetative, floral and post-harvest traits and examined the relationships among these characters through correlation analysis. The experiment was laid out in Completely Randomized Design with five replications under naturally ventilated polyhouse condition. Significant differences were observed among the genotypes for all the traits studied. Genotype V7 recorded the maximum plant height (33.60 ± 3.78 cm), leaf length (18.30 ± 1.57 cm), leaf breadth (11.06 ± 0.88 cm), petiole length (21.10 ± 3.58 cm), peduncle length (28.80 ± 3.83 cm), spadix length (4.40 ± 0.10 cm), life of spadix (136.20 ± 3.35 days) and vase life (21.20 ± 1.79 days). V15 recorded the highest number of leaves per plant (10.20 ± 0.84) and internode length (3.38 ± 0.43 cm), whereas V10 recorded the maximum spathe length (8.42 ± 0.82 cm) and breadth (9.00 ± 0.91 cm). Correlation analysis revealed strong positive associations between plant height and spadix length (r = 0.98, P < .001), plant height and life of spadix (r = 0.97, P < .001) and spadix length and vase life (r = 0.83, P< .001). In contrast, the number of flowers per plant showed no significant association with the other characters studied. Overall, V7 showed superior performance for several important vegetative and post-harvest traits, while V15 and V10 showed strengths in specific characteristics and may be considered promising genotypes for further validatory evaluation under protected cultivation and breeding programmes.
