Ray florets with closed tubular corollas (RC type), tubular-ligulated (RJ type) and ligulated (J type) in China aster (<i>Callistephus chinensis</i> (L.)Nees). Heredity

Abstract

The improper description and classification of two Polish cultivars of China aster ('Roma' and 'Srebrzysta Gwiazdka') were corrected. A new type of ray florets with tubular-ligulated (RJ type) and closed tubular (RC type) corollas was described. The type of heredity of the above mentioned types of florets and florets with ligulated corollas was determined. The work is based on our own material: radiomutant MG and its offspring as well as the F1
