The role of variety in increasing seed productivity of China Aster (Callistephus chinensis (L.) Nees)
Journal Title: Plant varieties studying and protection - Year 2015, Vol 0, Issue 1
Abstract
Рurpose. Determining the influence of the varietal features on seed productivity of China Aster when growing under conditions of Forest-Steppe zone of Ukraine. Methods. Field study during 2011–2013 on experimental field of Institute of Horticulture of the National Academy of Agriculture Sciences. Results. It was experimentally determined the influence of varietal features on seed productivity for various sort-types of China Aster. Based on morphological description, the growth and development of this plant was shown as well as dependence of generative organs on quantitative parameters of vegetative ones, and their impact on the productivity of various variety types either of the Institute of Horticulture or other scientific institutions breeding. Structure of flowers for various sort-types was illustrated. The most productive varieties were identified among those that are included in the State Register of plant varieties suitable for dissemination in Ukraine which have formed the average of 3 g of seeds or more per plant during the years of study. Conclusions. Edaphoclimatic conditions of the Forest-Steppe zone of Ukraine are favorable for seed-producing industry of China Aster. Its productivity considerably depends on a variety and sort-type to which it belongs.
