Evaluation of Lisianthus (Eustoma grandiflorum) Cultivars for Growth and Floral Characters under Prayagraj Agro-climatic Conditions

The present investigation entitled “Evaluation of Lisianthus (Eustoma grandiflorum) cultivars for growth and floral characters under Prayagraj agro-climatic conditions” was carried out from December, 2024 to May, 2025 under naturally ventilated polyhouse, Department of Horticulture, SHUATS, Prayagraj. Fifteen Lisianthus cultivars Arena Red, A Baby Pink, C Purple, A Pink, C Pink Picotee, A White, C Yellow, Croma III Lavender, C White, C Blue Picotee, A Clear Pink, Sunrise White, A Purple, A Gold, and C Green Ain were evaluated in a Randomized Block Design (RBD) with three replications. The results revealed significant variation among the cultivars for all parameters studied. Cultivar Arena Red (V1) consistently outperformed others in growth and flowering attributes, including plant height (44.5 cm), plant spread (26.7 cm²), number of primary branches (6.9) and number of sprays (6.9). It also recorded the earliest bud initiation (115.3 days) and first flowering (132.5 days). Floral quality was also highest in V1 with the highest bud length (3.9 cm), bud diameter (2.38 cm), stalk length (11.2 cm) and vase life (11.4 days). Cultivar A White (V6) followed closely, while C Blue Picotee (V10) showed poor performance in most traits. Based on the findings, Cultivars Arena Red and A White can be grown for protected cut flower production under Prayagraj conditions.
