VL Dhan 158: An early maturing rice variety for rainfed uplands of North-West Himalayas
Abstract
Early duration rice variety, VL Dhan 158 was developed by ICAR-Vivekananda Parvatiya Krishi Anusandhan Sansthan(VPKAS),Almora, Uttarakhand for cultivation under rainfed upland conditions of Uttarakhand and Himachal Pradesh during Kharif season. This variety was notified and released in 2017 by the Central Sub-Committee on Crop Standards Notification and Release of Variety for Agricultural Crops.VL Dhan 158 is derived from the cross RCPL 1-45 x VL 3861 with maturity duration of 110- 120 days. This has intermediate plant height, semi-erect panicle mostly exerted and plants are non-lodging. This variety has recordedaverage grain yield of 2,386 kg/ha in comparison to national check, Vivek Dhan 154 (1,722 kg/ha); regional check, Sukradhan1 (2,115 kg/ha) and Local check (1,905 kg/ha) with yield advantage of 38.53, 12.78 and 25.26 per cent, respectively, over these checks. It has exhibited high head rice recovery of 66.2%,intermediate ASV (4.0) and amylose content of 24.44%.It has shown resistance to brown spot(Cochliobolus miyabeanus) and blast(Magnaporthe grisea), the most serious disease of upland rice in Northern hill.
