Abstract

China aster [Callistephus chinensis (L.) Nees] is commercially grown as annual flower crop for cut flower and loose flower. It is used for flower decoration, preparation of bouquets and garlands. It belongs to the family Asteraceae and is native of China. Morphological characterization of China aster genotypes was carried out in the division of Floriculture and Medicinal Crops, ICAR-IIHR, Bengaluru during 2015-16 and 2016-17 by adopting DUS guidelines developed by Protection of Plant Varieties and Farmers Rights Authority, New Delhi. A total of 42 genotypes were characterized for 21 traits belonging to vegetative and floral traits. Among these 21 traits, two were monomorphic, four dimorphic and 15 were polymorphic indicating their potential for varietal characterization. This characterization clearly established distinctness among the different genotypes for various traits. This study will be useful for breeders/farmers to identify and differentiate China aster genotypes and to pursue protection under PPV and FR Authority, New Delhi. The characterizations of genotypes will also results trait specific information which can be used in the development of superior genotypes in China aster.
