Sweet sorghum is a new generation bio-energy crop with considerable tolerance to drought and salinity and amenable for multiple uses. Sweet sorghum has elicited the interest of breeder due to its capacity to provide renewable energy products, industrial commodities, food and animal feed. The sweet sorghum donor RSSV 313 is developed through a cross NSS223 x NARI 111 at MPKV, Rahuri through pedigree selection as identified and recommended as a donor parent in crop improvement programme based on specific physiological traits viz.; leaf area, LAI, plant height, stay green score, HUE, low HI and high biomass, stay green rating, juice brix0 and high biomass. Eleven sweet sorghum genotypes were evaluated for fresh biomass and physiological parameters at Rahuri from 2013-14 to 2015-16 (3 years). Among them RSSV 313 was observed to be promising for high biomass and physiological traits. The pooled mean of three years revealed that RSSV 313 recorded the highest fresh biomass (67.6 t/ha) as compared with the check CSV19 SS (58.2 t/ha) thus, amounting to 16.2 % increase over check. The physiological studies indicates that the sweet sorghum donor RSSV 313 equipped with great photosynthetic apparatus viz., high leaf area (75.9 dm2), high LAI (6.37), plant height (368 cm) and low HI (16.3%). The donor RSSV 313 was also observed to most efficient in converting the heat into biomass production owing to efficient utilization of solar radiation (0.028 HUE). The genotype RSSV 313 was therefore recommended as donor parent in sweet sorghum crop improvement programme during the Joint Agresco 2016 held at Dr. PDKV, Akola (Maharashtra).
