RESUMO

The gaining attention of underutilized oat crops for both food and feed, mining of quality and yield related genes/QTLs from available germplasms of oat is need of the hour. The large family of grasses has a vast number of germplasms that could be harnessed for bio-prospecting. The selection of cross-compatible oat germplasms by molecular markers could be used for the introgression of the novel traits into the elite background of oats. The process needs a thorough study of genetic diversity to see the evolutionary relatedness among germplasms. Considering this, in the present study, the genetic diversity of 38 oat germplasms with 12 agro-morphological traits was carried out using 22 Inter Simple Sequence Repeat (ISSR) markers. We found a high level of polymorphism and 158 distinctive alleles; on average 7.18 alleles per primer, further, high-yielding genotypes were identified with the help of phenotypic data and genetic diversity was analyzed by using DNA fingerprint-based principal component analysis, UPGMA dendrogram. Among these 38 germplasms; eight were identified as superior under high grain yield (OS-424, OS-403, NDO-1101, OL-10, UPO-212, OS-405, OS-6, and OS-346) and another eight germplasms were identified as superior for the high fresh weight (for fodder purpose, NDO-711, RO-19, OL-14, OL-1760/OL-11, NDO-10, UPO-212, UPO-06-1, and RO-11-1). These results suggest that germplasms that are closely related (Cross-compatible) and have good potential for desirable traits could be used for varietal development by using marker-assisted selection.

RESUMO

Influence of cowpea mosaic virus (CPMV) and common bean mosaic virus (CBMV) infection on the yield of extractable leaf protein of cowpea cvs. Pusa Phaguni, Pusa Barsati, and Yard Long was studied. An increase as well as decrease in the yield of leaf protein concentrate (LPC), due to virus infection, has been observed. CPMV infection increased LPC yield in all the cowpea cvs., but CBMV decreased it in cys. Pusa Phaguni and Yard Long. Variation in percentage of extractable nitrogen and protein in LPC was also notices. However, total N and protein in leaf and LPC were increased due to virus infection, but total sugar and starch decreased.
