Notification of crop varieties and registration of germplasm : Barley Variaty DWRB101

Abstract

DWRB101 (DWR28/BH581) is a new two-row malt barley variety, which was developed using pedigree method at IIWBR, Karnal. The variety was identified
for irrigated timely sown conditions of North Western Plains Zone (NWPZ) during 53rd All India Coordinated Wheat and Barley Worker’s meet held at JNKVV,
Jabalpur during 22-25 Aug. 2014. The variety was subsequently released by the “Central Sub-Committee on Crop Standards, Notification and Release of Varieties for Agricultural Crops (CVRC)†and notified by the Gazette Notification S.O. No. 268 (E) dated on 28th Jan, 2015 for irrigated timely sown conditions of North Western Plains Zone (NWPZ). DWRB101 was tested at a total of 31 locations with four checks viz. DWRUB52 and DWRB92 (both two-row type) and K 551 and BH 902 (both six-row type) under coordinated evaluation trials. DWRB101 exhibited average grain yield as 5010 Kg/ha (mean of 31 trials over 3 years). DWRB101 depicted superiority in grain yield over tworow malt barley checks DWRUB52 (6.6%), DWRB92 (4.8%) and six-row checks K551 (15.2%) and BH902 (7.7%), respectively. DWRB101 was differentiated from
DWRUB52 by molecular markers viz. Bmac213, Bmag382, HVM40, MWG634, GMS61, Bmag337, Bmag500 etc. In agronomical trials, at recommended
N dose, the proposed variety DWRB101 showed numerical superiority for grain yield over both two-row malt barley checks i.e. DWRUB52 (6.88 %) and
DWRB92 (1.86%), respectively.
