dc.description.abstractDevelopment of end product specific wheat germplasm is the comparatively newer objective in wheat breeding programme. Wheat breeding programme in our country has mainly focused on yield and resistance breeding. There has been no dedicated chapati quality breeding programme in until recent past. The present study aimed to decipher the basis of chapati quality and to develop premium quality wheat germplasm carrying high levels of stripe rust resistance and leaf rust resistance through pyramiding of Lr57/Yr40 and Yr15 rust resistance genes in premium chapati quality background. Analysis of chapati quality traits in specially constituted core set of wheat genotypes at multilocations of the state revealed that the environment in which wheat is grown has significant effect on grain quality. The major components of chapati making quality include various components such as dough handling, chapati colour, texture, flavor, taste, sweetness pliability etc. and should be given due weightage for deriving a composite chapati score. Chapati quality traits protein content (0.143), hectoliter weight (0.278), thousand grain weight (0.474), sedimentation volume (0.194), gluten index (0.260), water absorption (0.359), puffing height (0.302) were found to be positively correlated with overall chapati score. The negative correlation was found for phenol score (-0.149), water loss after baking (-0.198) and water loss after 4 hour (-0.380) with chapati score. The farinographic traits showed genotypic difference among genotypes. Identification and selection based on quick and reliable traits in segregating populations of targeted crosses is very important to develop germplasm with specific quality traits. In the segregating population, the F2 and F3 homozygous pyramided plants were identified for both the genes Lr57/Yr40 and Yr15 using KASP and SSR markers, respectively. The plants homozygous for both of the genes were further analyzed for agronomic and quality traits.en_US
