Sorghum grains are mostly used for the roti preparation. The M 35-1 (Maldhandi) a sorghum cultivar is known for its good quality of roti due to having pearly white grain color, its flour having higher water holding capacity, and good organoleptic taste. However, this cultivar is low yielder. To evolve sorghum high yielding genotype coupled with this good roti qualities, systematic breeding program was planned and executed to overcome this problem. Twenty local land races, 92 genotypes, and seven improved cultivars of sorghum along with check M 35-1 were studied for various nutritional quality parameters, with special reference to the roti quality. Considering nutritional quality and organoleptic evaluation parameters studied for roti quality, the local land races viz., RSLG 428-1, RSLG 1238, RSLG 1275 and the genotypes viz., RSV 290, RSV 292, RSV 858, RSV 859, RSV 861, RSV 868, RSV 894, RSV 985, RSV 992, RSV 995, RSV 999 were found to be promising for protein, sugar, water absorption, and soluble protein content. Therefore, they can be used for further improvement in nutritional quality through breeding program. Among the improved cultivars, Phule Vasudha (RSV 423), CSV 22, and Phule Chitra (SPV 1546) were found to be most promising for roti quality. The maximum score for overall acceptability was found for Phule Vasudha followed by Phule Anuradha (RSV 458), Phule Yeshoda (RSLG 262), and Phule Maulee (CSV 216).

Fourteen genotypes including two checks were evaluated for their yield and juice quality attributes. The yield and quality parameters of CSH 22SS were found to be promising followed by SPSSV 20 and SPSSV 15. While considering yield and juice quality parameters of initial sweet sorghum varietal trials entries CSV 19SS and SPSSH 18 were found to be promising among the new genotypes trials. Harvesting of crop at 30 days after 50 % flowering (hard dough stage) was appropriate to get desired 0 Brix, total sugars and TSI. The CSH 22SS was found promising followed by CSV 19SS, PAC 52093 and SSV 84. The harvested sweet sorghum stalks must be processed as early as possible to avoid the loss of sugars/ethanol.

The investigation on an assessment of sweet sorghum cultivars for ethanol production was carried out during month of June-October, in Kharif 2008 and 2010. Twenty sweet sorghum genotypes were evaluated for juice yield and sugar quality parameters. The maximum juice yield, total sugars and calculated ethanol yield were observed in the genotypes SPSSH-31, SPSSH-29, SPSSV-35 and SPH-1670 in Kharif trials. While harvesting period of sweet sorghum at 45 days after 50% flowering is appropriate to get desired o brix, juice yield and total sugars. The genotype CSV 19 SS was found promising for juice and sugar quality parameters followed by CSH 22 SS and SPSSV 6.
