Abstract: Development of resistant variety better suited to drought is the prime objective of many wheat
breeding program across the globe. Fifty elite bread wheat lines received from CIMMYT, Mexico as 21 semi-
st
arid wheat yield trial were planted in randomized complete block design with two replications at Barani
Agricultural Research Station, Kohat during the cropping season 2013-14. Data were recorded on days to
heading, days to maturity, plant height and grain yield. Analysis of variance revealed highly significant
differences among genotypes for all the traits studied. Twenty two (22) lines viz. E-308, 309, E-313-16, E-21-26,
E-28, E-331-332, E-335, E-38, E-41-42, E-44, E-48 and E-49 were found higher yielding and disease resistant than
check cultivar KT-2000. These entries need further scrutiny in preliminary and advance wheat yield trial for yield
against multiple checks and across multi locations.

INTRODUCTION from CIMMYT, Mexico as 21 semi-arid wheat yield trial
Wheat (Triticum aestivum L.) is the staple food for a potential, drought tolerance and disease resistance. Local
large part of the world population including Pakistan. check cultivar KT-2000 was added as Entry 301. All the
Wheat is one of the most important cereal crops in terms entries were sown in rows 30 cm apart and 5 m long on
of production and utilization. It is a source of energy, 30-11-2013 at BARS Kohat, keeping the plot size of 5 x 1.8

Therefore, there is need to improve wheat yield potential and are presented in Table a. Similarly, rainfall data during

many wheat breeding program across the globe. However,
the success achieved so far is not up to the mark and
need due consideration in current and future breeding
schemes. Therefore, the present study was undertaken to
select early maturing, high yielding and disease resistant
wheat line for rainfed areas of Khyber Pakhtunkhwa,
Pakistan.
MATERIALS AND METHODS
This experiment was under taken at Barani
Agricultural Research Station (BARS) Kohat, during
2013-2014 cropping season. The experimental material
comprised of forty nine (49) wheat genotypes received
st
(SAWYT) during Rabi-2013-14 to be tested for yield
