Variations in Phenological Traits in Wheat and Their Association with Grain Yield under Late Sowing Conditions

Variations in Phenological Traits in Wheat

Abstract

Morphological and physiological attributes play crucial roles in wheat yield. Estimation of grain yield of wheat represents a vital necessity for actual crop management. Within this investigation we evaluated the associations between yield, biomass production, plant height and the tillers number in various growth phases. For this initiative, we assessed eleven wheat genotypes in Randomized Complete Block Design (RCBD) with three replications in late sowing conditions. The research was directed at the Prof. Dr. Purnendu Gain Field Laboratory Farm, Agrotechnology Discipline, Khulna University. Data were assembled on diverse growth and yield parameters. Analysis of variance (ANOVA) was performed on different morphological characters and yield. Based on ANOVA it was found that plant height, tillers production, dry matter accumulation, and yield differed among the wheat varieties. The wheat grain yield significantly correlated both with plant height and above-ground biomass. Regression analysis revealed that the involvement of tiller m^-2 to the change of grain yield was 66.5%; but the influence of dry matter m^-2 to grain yield was 87.5%. These results underscored the significance of stressing the characters like plant height, tillers m^-2 and dry matter m^-2 in wheat development plans to improve grain yield, which had real link with wheat production as these have displayed positive and noteworthy correlations with wheat yield under late sowing environment.
