International Journal of Chemical Studies · 2018 · Vol. 6(4) · pp. 3324–3325

Abstract

The variety trials under hill ecosystem are conducted with an objective of identifying high yielding promising cultures with cold tolerance, three genotypes were evaluated under assured rainfall conditions against national (Vivekdhan 62) and regional (HPR 2143) check varieties during 2010, 2011 and 2012 Kharif season. Maximum panicle length of 22.9, 23.8 and 22.7 cm was recorded in IET 21765 during 2010, 2011 and 2012 respectively. Maximum grain yield of 4050, 4213 and 4009 Kg ha-1 recorded in IET 21759 during 2010, 2011 and 2012 respectively. Maximum straw yield of 9548, 9934 and 9452 Kg ha-1 recorded in HPR 2143 during 2010, 2011 and 2012 respectively. The genotype IET 21759 showed superiority over checks for productivity with desirable quality parameters hence could be suitable genotype for heavy rainfall hilly regions of Karnataka State.
