Morpho-Physiological Analyses of Selected Wheat Genotypes

Abstract

Present research evaluated seventeen genotypes of wheat along with three check varieties (PS-05, Siran and Atta-Habib) under the field conditions of Agriculture Research Station (ARS) Baffa, Mansehra to identify the most suitable and high yielding variety based on morpho-physiological/agronomic traits. The experiment was carried out during 2013-14 in Randomized Complete Block Design (RCBD) with three replications. Data showed significant differences for almost all of the traits. Maximum spike length (14.5 cm, 14 cm, and 13.8 cm), number of grains per spike (95, 94 and 87) and grain yield (5825 kg ha-1, 5666 kg ha-1and 5567 kg ha-1) were recorded for genotypes 105, 108, 110 respectively. While maximum 1000 grain weight (60 gm, 50 gm and 48 gm), was recorded for genotypes 132, 105, 108 and 110 correspondingly. Similarly maximum number of tillers (13.5) and plant height (101.6) were recorded for genotypes 118 and 132 individually. On the other hand minimum days to germination (9), plant height (65.5), spike length (9.2), number of grain per spike (68.5), 1000 grain weight (40) and grain yield (2667 kg haˉ1) were observed in the genotypes A-Habib, 105, 117, 132, 101 and 126 respectively. Correlation analyses revealed that spike length, number of grains per spike and grain yield per hectare was positively and significantly correlated with each other. While significantly negative correlation was observed for plant height with spike length, number of grains per spike and grain yield per hectare. Due to high yielding ability the genotypes 105, 108 and 110 are recommended for general cultivation in Mansehra and similar climatic regions.
