Abstract
In 2006-2008 26 wheat varieties were tested, created at IPGR Sadovo during the period 1948-2006 as well as the Bezostaya1 variety. Biometric measurements were made on some elements of productivity – number of productive tillers, harvest index, plant height, above-ground dry mass, vegetation period, number of grains in wheat ear, mass of grain in wheat ear, weight of grain per 1m2 area, number of stem wheat-ears per 1 m2 area, some morpho-physiological indices – flag leaf width, mass of 1 leaf, loss of leaf mass per 1 plant, loss of leaf area per 1 plant, measured in two phases of the wheat plant development. Detailed agro-meteorological statistics about the years of study is shown in our previous publication.
The data of the measurements were mathematically processed by a computer program SPSS 9.0 for Windows. A regression equation was derived, explaining the quantitative modification of the grain yield per unit area in a “unit” change of any of the studied indices.
As a result of the study a model of a wheat plant was created suitable for the dry climate conditions in Sadovo, characterized by high grain yield.
