Morphological phenotyping of cultivars of winter wheat for selection of genotypes with high adaptive potential

Abstract

The purpose. To carry out phenotyping and screening of cultivars of wheat of steppe ecotype for selection of genotypes with high adaptive potential in conditions of Forest-Steppe. Methods. Field, laboratory, mathematical-statistical. Results. The methodology of recent trend of phenomenology of plants for selection of genotypes with high adaptive potential in conditions of field screening is offered. Key parameters of phenotyping are analyzed. Conclusions. Phenotyping as integral criterion of physiological state of plants enables to determine boundaries of adaptive variability and extent of durability of genotype. The conducted morpho-physiological phenotyping of cultivars of winter wheat of steppe ecotype in conditions of influence of environmental factors has allowed selecting material of new productive cultivars which biological properties are in the best way fitted for conditions of Forest-Steppe.
