Screening of Wheat Genotypes for Morphological, Physiological and Phenological Traits Under Climatic Condition

Abstract

Climate change is a major threat to most of crops grown globally in sub-tropics and tropics. One of the consequences of climate change is drought, which has a negative effect on crop growth and productivity. However, present research drought affected breed wheat was tested to examine the quality of wheat selection for different stage using morphological and phenological traits. Ten genotypes along with two local check varieties were tested in randomize complete block design were used for this experiment. The experiment was conducted in the field of Southern Wheat Research Station, Agriculture Research Institute, Tandojam, in winter season to determine the different levels of tillers per plant, growth vigor, early growth habit, plant type, Leaf type, content of proline in (μ mol. g^-1 fresh wt), osmotic potential in (-Mpa) and relative water content in (%) analyzed for significance. The genotypes showed positive significantly differ in response to studied traits. Ten genotypes were sown in three replications, in two blocks. The genotypes were significantly different in response to the moisture stress. There were highly significant differences for all traits. The positive association for studied the parameters between the field trials demonstrated that greater seedling vigor of root and shoot is key factor influencing in wheat. Therefore, our finding suggested that these genotypes had potential to grow well and perform better than other genotypes and check varieties.
