TAILIEUCHUNG - Heterotic responses for yield and its components in faba bean (Vicia Faba L.)

The present investigation was carried out during the year 2016-17 and 2017-18 at Narendra Deva University of Agriculture and Technology, Ayodhya with the objective to estimate heterotic responses in yield component traits in 45 hybrid combinations developed by crossing 15 lines (females) with 3 testers (males). The experiment was laid out in randomized complete block design with three replications and observations were recorded on 5 randomly selected plants for 12 quantitative traits. Heterosis was estimated as per cent increase or decrease of F1 value over better parent (BP) and two standard varieties (SV) viz., HFB 1 (SV1) and Vikrant (SV2). Significant positive as well as negative heterosis was observed for days to 50 per cent flowering, days to maturity, plant height (cm), number of branches per plant, number of pods per plant, pod length (cm), number of seeds per pod, 100-seed weight (g), biological yield per plant (g), harvest index (%), protein content (%)and grain yield per plant (g). The estimates of heterobeltiosis and standard heterosis for twelve characters of forty five crosses have been presented and discussed in the present study. The most desirable crosses showing high mean performance along with high and significant heterobeltiosis and standard heterosis for grain yield per plant merit further testing and evaluation in adaptive trials to find out their feasibility for recommendation as hybrid cultivars of faba bean. | Heterotic responses for yield and its components in faba bean (Vicia Faba L.)
