Mapping of molecular markers linked with MYMIV and yield attributing traits in mungbean

Published on

The present study employed recombinant inbred lines
(RILs) derived from the cross between a susceptible cultivar
Sonali and resistant wild relative of mungbean (Vigna
radiata var. sublobota to map molecular markers linked
with mungbean yellow mosaic Indian virus (MYMIV)
resistance and yield attributing traits in mungbean.
Resistance to the virus was evaluated in RIL population
under field conditions during two consecutive years 2013
and 2014. A set of 224 molecular markers were employed
for the identification of polymorphism between parents.
Only 46 markers showed polymorphism between Sonali
and V. radiata var. sublobota. Twenty two polymorphic
markers were used to construct a linkage map comprising
11 linkage groups. QTL analysis identified molecular
markers linked with MYMIV resistance and agronomic traits
viz., no. of pods per plant, no. of seeds per pod and 100-
seed weight. Molecular markers identified to be linked with
MYMIV were confirmed in 93 diverse mungbean accessions
screened for yellow mosaic disease. The molecular markers
linked to the MYMIV and yield attributing traits identified in
this study will be useful in marker assisted breeding for
development of high yielding mungbean varieties resistant
