Out Standing Performance and Molecular Profiling of Barley Entry “HUB-113'' Across the Location for Yield and Resistance Against Spot Blotch Disease Caused By Bipolaris sorokiniana.

A new high yielding along with resistance against spot blotch disease barely variety viz., “HUB-113’’ derived from Karan 280 / C 138 has been developed by the Department of Genetics and Plant Breeding, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi. Before its release it was tested under all India Coordinated Trial, conducted by ICAR, New Delhi, including molecular profiling with three reference barley varieties namely K-508, RD-2552 and Jyoti. On the basis of its outstanding performance for yield, resistance for spot blotch disease caused by Bipolaris sorokiniana fungal pathogen and other desirable traits, Central Varietal Release Committee has approved for its release in 2013 for the cultivation as feed barley in the NEPZ of the country under timely sown irrigated conditions. During three years of field testing/trial at 18 locations HUB-113 exhibited best performance over all standard checks for yield and resistance against spot blotch disease. In 18 trials conducted at different research station, HUB-113 performed 10 times superior (maximum) followed by all the checks. It had average yield of 48.55 q ha^-1 with yield potential of 59.6 q ha^-1 during trials. Besides above it is ideal for days to maturity, plant height, protein contents, wax appearance on the plant surface, etc. Further clustering/dendrogram revealed that HUB-113 belongs to single cluster and showed 90 per cent similarity with Jyoti, K 508 followed by RD 508 checks. Developed desirable variety further would assist breeder to use as parent for crop improvement under breeding program for yield, resistance and another economically important traits.
