SUMMARY
CSV 30F, a new single cut forage sorghum variety developed from the cross NSS 223 x NARI 111 at Rahuri was found superior in green and dry fodder yield over three checks viz., CSV 21F, HC 308 and Local variety. Average of 44 tests, it gave the green fodder yields of 443.4 q/ha against 413.8 q/ha of CSV 21F and 417.7 q/ha of HC 308 and 400.9 q/ha of local variety, thus amounting to an increase of 7.2, 6.2 and 10.6 per cent over checks, respectively. In respect of dry fodder yield, it gave the yields of 139.6 q/ha against 125.3 q/ha of CSV 21F and 125.4 q/ha of HC 308 and 118.9 q/ha of Local variety, thus amounting to an increase of 11.4, 11.3 and 17.4 per cent over checks, respectively. Besides being the higher yielder, SPV 2057 had tall plant stature (267 cm) and flowered in 76 days. It was tolerant to shootfly (37.4% dead heart), stem borer (20.6%) and leaf blight (4.55 scale), Anthracnose (3.90 scale), Zonate leaf spot (3.30 scale) and Gray leaf spot (4.20 scale). It had higher protein yield (9.67 q/ha), low HCN ppM (56.5), higher IVDMD (50.2%), higher DDM (57.6 q/ha) and more TSS (8.86%). This variety was observed to be more vigorous with higher number of leaves, leaf length, width, girth and leaf stem ratio. Due to distinct superiority in yield and forage quality parameters coupled with tolerant to shootfly, stem borer and foliar diseases were found over the CSV 21F, HC 308 and Local variety. The variety SPV 2057 was therefore, recommended for release by 43rd Annual Group Meeting of Sorghum scheduled on 20 to 22 April 2013 at DSR Hyderabad for the cultivation in the kharif forage sorghum growing states of Zone I (Rajasthan, Gujarat, Uttarakhand, UP, Haryana and Punjab) and zone II (Maharashtra, Karnataka and Tamil Nadu) of India for single cut.
