Nutritional Quality of Yellow Mosaic Disease Resistant Versions of Soybean Cultivar JS335

Abstract

Present investigation reports the morphological and nutritional parameters in yellow mosaic disease (YMD) susceptible soybean genotype JS335, resistant genotypes G. soja (wild species) and G. max Cv. SL525 and resistant versions of JS335 introgressed with genes from wild/cultivated species. Seeds from different soybean genotypes were collected at maturity from crop raised in the experimental fields at Punjab Agricultural University, Ludhiana in 2017. Visual symptoms include formation of chlorotic yellow patches on leaf lamina and reduced leaf size of susceptible genotype JS335 whereas G. soja, SL525 and resistant lines of JS335 with G. soja (JS-GS) and SL525 (JS-SL) did not show disease symptoms. JS-GS and JS-SL lines showed higher seed yield and 100 seed weight as compared to susceptible genotype JS335. Higher contents of total soluble proteins, total soluble sugars, reducing sugars and lipids were recorded in seeds of improved JS335 lines in comparison to susceptible JS335 whereas amino acids, phenolic constituents, sucrose and minerals showed the opposite trend. The resistant JS335 lines showed improved resistance to yellow mosaic disease and higher physiological parameters indicating them to be better in performance as compared to susceptible JS335 under agroclimatic environment of Punjab in Northwest India.
