The path analysis and correlation in twelve distinct Alstroemeria genotypes viz., Capri, Piantum, Riana, Pluto, Pink Panther, Ooty Collection-1, Ooty Collection-2, Ooty Collection-3, Ooty Collection-4, Darjeeling Collection-1, Darjeeling Collection-2 and Darjeeling Collection-3, were studied during the academic year 2023-2024 at the department of Floriculture and Landscaping, College of Horticulture, Mudigere. The correlation studies revealed that the number of leaves per plant (0.878), leaf length (0.765), leaf width (0.785), leaf area (0.914), number of flowers per spike (0.907), flower diameter (0.876) and stalk weight (0.889) showed significantly high positive correlation with number of spikes per square meter. It showed significantly high negative correlation with days taken for flower bud initiation (-0.774). Path analysis for spike yield per m 2 showed that plant height (0.523), stalk length (0.328), leaf area (0.982), number of flowers per spike (0.971), number of leaves (0.182), leaf width (0.059), flower diameter (0.037) and stalk weight (0.118) have positive direct effect.
This suggests the potential for enhancing spike yield by directly selecting these traits. Consequently, more focus is placed on these characteristics when choosing genotypes for crop improvement.
