Genetic Variability and Heritability of Tuberose (Polianthes tuberosa) Cultivars under Agro-Climatic Conditions of Prayagraj

Abstract

The present study entitled “Genetic variability and heritability of Tuberose cultivars under agroclimatic conditions of Prayagraj” was made to identify the suitable variety for growing in Prayagraj, Uttar Pradesh. Fifteen varieties were laid out in Randomized Block Design with three replications during May 2022 to February 2023 at Departmental field of Horticulture, NAI, SHUATS, Prayagraj. The observations recorded on various growth, yield and quality contributing characters. The result from the present investigation revealed the genotypes Arka Suvasini, Mexican single and Hyderabad single are identified as higher spike yield per plot which indicated that these genotypes may be shown for higher yield at Prayagraj Agro-climatic condition. The PCV were higher than GCV for all the characters taken in to consideration. High magnitude of GCV and PCV was recorded for No. of bulblets per plant, weight of bulb per plant , yield of bulb per hectare and weight of bulb and least estimates for PCV and GCV was observed for no. of leaves at 6 month after planting. Heritability and genetic advance indicate that the additive nature of gene action and reliability of those characters for selection and emerged as ideal traits for improvement through selection.
