High intensity of phothsynthetic active radiation (PAR) as factor of wheat selection on potential productivity

In controllable conditions the authors selected the individual plants from population of the 232 cultivar on determinant of «maximum corn amount in ear». It was shown, that the use of high intensity of PAR during cultivation of thick planting wheat permit to reveal the high productive forma (biotypes) inside of varietal population since the plants may at that realize their genetic potential of productivity. Revealed lines with high corn amount in ear may be used both for increase of potential productivity of original variety and as the material used in further crossings.
