Glycine soja Siebold & Zucc. PI 393551 carries
gene(s) for resistance to yellow mosaic disease,
which is caused by Mungbean yellow mosaic
India virus (MYMIV). Yellow mosaic disease is a
serious constraint to soybean [Glycine max (L.)
Merr.] production in India. However, the gene(s)
imparting resistance to MYMIV in G. soja have
not yet been mapped. In the present study, three
F2 populations derived from crosses of the three
G. max cultivars ‘Ankur’, ‘Sawarn Vasundhra’,
and ‘JS335’ with PI 393551, the donor for MYMIV
resistance, were phenotyped for reaction to
MYMIV at the geographic hot spot for yellow
mosaic disease to determine inheritance of
MYMIV resistance in PI 393551. All three F2
populations exhibited a 15:1 ratio of individuals
resistant and susceptible to MYMIV, indicating
duplicate dominant inheritance of MYMIV resistance genes. Further, a large F2 population (1520
plants) reconstructed from JS335 ´ PI 393551
was used for mapping MYMIV resistance
genes. Bulked segregant analysis identified
two genomic regions associated with MYMIV
resistance, one on chromosome 8, and another
on chromosome 14. A total of 78 plants with
100% MYMIV infection, which were expected
to be homozygous for recessive genes, were
genotyped using polymorphic simple sequence
repeat (SSR) markers near linked markers
on chromosome 8 and 14. Genetic analyses
revealed tight linkages of MYMIV resistance
with SSR marker BARCSOYSSR_08_0867
(15,434,295 bp) on chromosome 8, and with
BARCSOYSSR_14_1416 (47,686,933 bp) and
BARCSOYSSR_14_1417 (47,738,940 bp) on
chromosome 14. The identified SSR markers
that are tightly linked to MYMIV resistance
genes will be useful for introgression of MYMIV
resistance from G. soja into G. max.
