Abstract
The investigation entitled “Studies on character association and path analysis for yield and quality parameters in stock (Matthiola incana L.) genotypes" was conducted at the College of Horticulture, Mudigere under KSNUAHS, Shivamogga, 2022-23. The experiment consisted of 11 genotypes, which were replicated thrice in a Randomized Complete Block Design (RCBD). The result revealed that the genotype Stock Katz Blue recorded the maximum plant height (72.00 cm) and internodal length (2.99 cm). The maximum number of leaves and leaf area was observed in the genotype Stock Katz Ruby (70.73 and 3199.94 cm2/plant, respectively). The minimum days taken to flower stalk emergence, first visible flower and harvest (43.60, 55.40 and 74.40, respectively) were recorded in Stock Katz Ruby. The maximum stalk length (93.93 cm), florets per stalk (32.07) and vase life (13.47 days) were recorded in Stock Katz Blue. The genotype Arrow White recorded the maximum number of cut flowers per sq. m (25.00) and number of cut flowers per 1000 sq. m (20000). Correlation studies revealed that plant height, leaf area and number of florets per stalk with stalk length; stalk girth with days taken for stalk emergence showed a significant positive correlation, whereas plant height, leaf area, intermodal length and stalk length showed significant negative correlation with days taken for stalk emergence. The number of cut flowers per sq. m exhibited highly positive direct effect of path coefficient analysis with the plant height, leaf area, number of florets per stalk and stalk girth. This suggests that these are the potential traits in improving the stalk quality and marketable flower yield.
