The major constraints and challenges in mungbean research and development are
susceptibility to MYMV, insect pests, small sized seeds, non-synchronous mahtrity and low
yield. Considering the fact, a field experiments on varietal improvement of mnngbean
received the genetic materials from A VRDC and local landraces were carried out at Rampur,
Nawalpill and Nepa1gunj. In observation nursery (OBN), VC 6153 (B-19) [568 kg_ha] , VC
6173 (B-33) [529 kg_ha] and VC 6173 C [526 kg_ha] were the best performing mnngbean
genotypes over the years 20 l 0-20 II and these lines will be selected for yield advance trial. In
coordinated varietal trial (CVT), the genotypes Bari mung(575 kg/ha) and VC6153B-20G(572
kg/ha) were the good yielder than the check Pratikcha(477 kglha) in maize based cropping
system. Mw1gbean cultivars named Pratikcha(767 kglha), Saptari local(750 kg/ha),
VC6153B-20G(715 kg/ha), VC 3960A-88(713 kg/ha), VC 6173B-6(707 kglha) and Bari
mung (700 kg/ha) were the best performers in rice-wheat-nmngbean cropping system and
significantly differed among the tested lines over the years(2010-2011) and across the
locations(Nepalgunj and Parwan ipur). However the mungbean grain yield of the year 20 II
was observed incredibly low due to the soil moisture stress during the cropping season as a
consequence affected to the mean yield performances. In pre-release varietal trial, genotype
BARJ mung ( 1177 kg/ha) and HUM-16(1 052 kg/ha) were the best perfonning genotypes than
the check Pratikcha(l021 kg/ha). It had also earlier matllfity with the highest number of pods
bearing capacity. Therefore seed of these lines should be increased at station and farm level so
as to help in varietal promotion and scaling up into the targeted areas
