Evaluation of ethanol fermentation efficiency of sweet sorghum syrups produced by integrated dual-membrane system.

1G ethanol from sweet sorghum can be a better alternative to various other sources used for its production. The commercial feasibility is dictated by the high sugar containing varieties, their transport to ethanol plants, storage and availability of robust yeast strains for the fermentation. Eight sweet sorghum cultivars namely CSV19SS, CSV24SS, CSV27, CSV32F, PV, SSV84, RVICSH, SPV1871, SSV74 were tested for their sugar content and varieties-SSV84 and CSV24SS were containing sugar content of 170-190 g/L.

Sweet sorghum as biofuel feedstock: recent advances and available resources.

Sweet sorghum is a promising target for biofuel production. It is a C4 crop with low input requirements and accumulates high levels of sugars in its stalks. However, large-scale planting on marginal lands would require improved varieties with optimized biofuel-related traits and tolerance to biotic and abiotic stresses.

Inheritance and molecular mapping of Rf6 locus with pollen fertility restoration ability on A1 and A2 cytoplasms in sorghum.

Of the several male sterility cytoplasms available as an alternative to the widely exploited A1 (milo) cytoplasm in sorghum, A2 is more suitable for commercial exploitation. Diversification of genetic and cytoplasmic base of hybrids involving A2 cytoplasm necessitates mapping of fertility restorer (Rf) genes for use in marker-assisted restorer development. We mapped a major male fertility restoration locus on sorghum chromosome 4 tightly linked with SSR markers, SB2387 and SB2388.
