12. Morpho-genetic studies on indigenous wheat genotypes at agro-climatic conditions of Haripur
Abstract
This study was carried out at the research fields of The University of Haripur, during 2014-15 to evaluate three high yielding genotypes on the basis of their morphological characters using randomized complete block (RCB) design in three replications. Data were documented on ten traits viz., days to maturity (days), plant height (cm), flag leaf area (cm2), days to flowering initiation (days), stem girth (mm), number of tillers plant-1 (#), spike length (cm), spikelet’s spike-1 (#), seeds spike-1 (#) and 1000-seed weight (g). Highly significant differences were detected among the tested wheat genotypes for all the studied traits. Data for days to maturity ranged from 166 to 171 days, for plant height 82.3 to 103.6 cm, for flag leaf area 67.8 to 88.2 cm2, for days to flower initiation 104 to 114.7 days, for stem girth 4.8 to 5.2 mm, for number of tillers plant-1 12 to 15.6 tillers, for spike length 11.9 to 12.0 cm, for spikelets spike-1 19.4 to 22.3 spikelets, for seeds spike-1 50.3 to 58.2 seeds and for 1000-seed weight 38.2 to 53.8 g. Generally, high heritability was estimated for the studied traits which varied from 57 % to 99 %. Days to flower initiation exhibited highest heritability value, whereas, minimum heritability was recorded for number of tillers plant-1. Based on the results of the current study, genotype Pirsabak-08 could be recommended for general cultivation in the agro-climatic conditions of Haripur.
