Stability of green pod yield and its components in faba bean (Vicia faba L.)

Abstract

An experiment was conducted during winter season (October-February) (2008, 2009 & 2010) to study the stability parameters, viz., regression coefficient (bi) and mean square deviations (s2di) from linear regression, along with per-se performance of 20 faba bean genotypes for 10 green pod yield related traits. The genotype HAVFB-41 (23.74 t/ha) was the top green pod yielder, stable and suitable for favourable environment, while it was also suitable for unfavourable environment for days to 1st picking (88.33 days), pod breadth (1.12 cm) and pod girth (1.04 cm). The genotype HAVFB-37 was also promising, stable and suitable for favourable environment for green pod yield (23.06 t/ha), number of branches/ plant (6.18), harvest index (51.41%) and pod length (6.13 cm).
