The aim of this study was to screen Indian cultivated wheat varieties and list out the parameters/genes required to be improved for an end-product. Therefore, 30 Indian wheat varieties under cultivation by farmers were screened for 14 physico-chemical and rheological parameters, sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) for high molecular weight glutenin subunits (HMW-GS), DNA based molecular markers for low molecular weight glutenin subunits (LMW-GS) and puroindolines (Pin) genes. Based on grain texture, sedimentation value, farinographic, alveographic, HMW-GS and LMW-GS and biscuit making parameters, HS490 was found to be a highly suited for biscuit and soft wheat products. HI1563 and DBW14 were also found to possess characteristics such as low protein, low to medium SDS-sedimentation value and combination of 2*, 7?8 and 2?12 (HMW-GS). DBW14 also had LMW alleles desirable for biscuit quality. DBW14 needs to be improved for grain softness to make it suitable for biscuit quality while both grain softness and LMW alleles need to be improved for HI1563 to improve its biscuit spread factor and alveographic indices for extensible gluten. Rest varieties showed moderate to very strong gluten but the gluten lacked extensibility. Only four varieties K307, DBW39, NI5439 and DBW17 possessed high flour protein and moderately strong gluten. They had more balanced deformation energy (W) and configuration ratio (P/L) combination suggestive of strong and extensible gluten needed for raised bread making. Marker assisted backcross breeding is suggested as solution to produce end-use specific varieties where appropriate alleles at only a few loci need to be incorporated.

Grain softness has been a major trait of interest in wheat because of its role in producing flour suitable for making highquality biscuits, cookies, cakes and some other products. In the present study, marker-assisted backcross breeding scheme was deployed to develop advanced wheat lines with soft grains. The Australian soft-grained variety Barham was used as the donor parent to transfer the puroindoline grain softness gene Pina-D1a to the Indian variety, DBW14, which is hard grained and has PinaD1bPinbD1a genes. Foreground selection with allele-specific PCR-based primer for Pina-D1a (positive selection) was used to identify heterozygous BC 1 F 1 plants. Background selection with 173 polymorphic SSR primers covering all the 21 chromosomes was also carried out, in the foreground-selected BC 1 F 1 plants. BC 1 F 2 plants were selected by ascertaining the presence of Pina-D1a (positive selection) and absence of Pina-D1b (negative selection). Using the approach of positive, negative and background selection with molecular markers, 15 BC 1 F 2 and 31 BC 2 F 1 plants were finally selected. The 15 BC 1 F 2 plants were selfed and the 31 BC 2 F 1 plants were further backcrossed and selfed to raise BC 3 F 1 and BC 2 F 2 progenies, respectively. A part of the BC 2 F 2 seed of each of the 31 plants was analyzed for grain hardness index (GHI) with single-kernel characterization system. The GHI varied from 12.1 to 37.1 in the seeds borne on the 31 BC 2 F 1 plants. The reasons for this variation and further course of action are discussed.
