Abstract
Barley experiments were conducted for three years at
multi-locational test sites in highland Balochistan ranging
from 1750 to 2250m elevation in order to evaluate barley
lines suitable for spring planting. Such lines have to
have characteristics of enhanced drought tolerance. short
maturity and sustained yield to be successful under the
harsh environmental conditions experienced in highland
Balochistan. Selection parameters such as. erect growth
habit. low tillering. high kernel weight. high harvest index
and tolerance to heat and terminal drought stresses have
been found to be associated with more consistent grain yield
in spring-sown barley in the variable environments of the
highlands.
One line. W12291/W12269. has been selected after three
years of testing as it was found to be more tolerant to
environmental stresses and gave higher grain yields than the
local barley landrace under dry conditions.
