Barnyard millet (Echinochloa spp.) is an important crop from nutritional point of view, nevertheless, the genetic information
is very scarce. In the present investigation, rice and finger millet genomic SSRs were used for assessing cross transferability,
identification of polymorphic markers, syntenic regions, genetic diversity and population structure analysis of barnyard millet
genotypes. We observed 100% cross transferability for finger millet SSRs, of which 91% were polymorphic, while 71%
of rice markers were cross transferable with 48% polymorphic out of them. Twenty-nine and sixteen highly polymorphic
finger millet and rice SSRs yielded a mean of 4.3 and 3.38 alleles per locus in barnyard millet genotypes, respectively. The
PIC values varied from 0.27 to 0.73 at an average of 0.54 for finger millet SSRs, whereas it was from 0.15 to 0.67 at an
average of 0.44 for rice SSRs. High synteny was observed for markers related to panicle length, yield-related traits, spikelet
fertility, plant height, root traits, leaf senescence, blast and brown plant hopper resistance. Although the rice SSRs located
on chromosome 10 followed by chromosome 6 and 11 were found to be more transferable to barnyard millet, the finger
millet SSRs were more polymorphic and transferable to barnyard millet genotypes. These SSR data of finger millet and rice
individually as well as combined together grouped the 11 barnyard millet genotypes into 2 major clusters. The results of
population structure analysis were similar to cluster analysis.
