Abstract
One varietal trial each in urdbean and mungbean, each comprising 10 varieties released during succeeding years since 1975, was conducted following randomized complete blockdesign (RCBD) in three replications during kharif 2013.The analysis of variance showed significant differences among varieties in each trial. Significant genetic advances were observed for earliness in newly released varieties of both urdbean (~ 4 days) and mungbean (4.6 days), implying substantial gain in per day productivity. Newly released varieties urdbean (DBGV-5 and IPU 2-43) did not display any yield advancement over the oldest one (T-9). However, a significant genetic gain in yield (62.60 kg/ha) was recorded in mungbean due to a recently released variety ‘DGGV-1’, indicating about 60% contribution of improved varieties towards increase of national average yield (105 kg/ha) during the period 1990-2015. In conclusion, the increased area coverage underHYVs having multiple disease resistance and better agronomic practices could reasonably explain the productivity (average yield) gains in both urdbean and mungbean.
