Abstract
An experiment was performed in the experimental field of Cereal Crops Research Institute (CCRI) Pirsabak, Nowshera, Khyber Pakhtunkhwa, Pakistan during the year 2015-2016 to evaluate wheat genotype based on morphological characters. Twenty wheat genotypes were evaluated under normal conditions using a randomized complete block design. Days until heading, thousand grain weight, plant height, grain yield, spike length, spikelets per spike, biological yield, and harvest index were all substantially different (P ≤ 0.05). Days to heading varied from 108.6 to 114.6 days, plant height from 84.0 to 100.6 cm, spike length from 8.43 to 10.63 cm, spikelet’s spike-1 from 15.9 to 20.4, 1000-grains weight from 58.3 to 70.80 g, the biological yield from 4333.3 to 8666.7 kg ha-1, grain yield from 2043.0 to 3713.3 kg ha-1 and harvest index from 18.63 to 29.30 %. The early heading genotype was CT-13052 (108.6 days), minimum plant height was shown by DN-120 (84.0 cm) and maximum spike length was exhibited by genotype DN-122 (10.63 cm). Similarly, check cultivar Pakhtunkhwa-2015 showed maximum spikelet’s spike-1 (20.4 no) and the highest 1000-grains weight was recorded in genotype AUP-07014 (70.80 g). Maximum grain yield was exhibited by genotypes PS-35 (3713.3 kg ha-1) followed by other genotypes CDRI-SA-12 (3180.0 kg ha-1), CT-13052 (3066.7 kg ha-1), PS-28 (3000.0 kg ha-1) and DN-120 (2949.3 kg ha-1). Heritability estimates were moderate for most of the traits due to the influence of environmental conditions than the genetic make-up of plants. Genotypes expressed a high heritability estimate for biological yield. For yield and yield-related attributes, the genotypes AUP-07014, PS-35, CT-13052, and Pirsabak-13 were recommended, and they might be employed in future breeding projects to improve grain production in bread wheat.
