Ornamental plants (trees, shrubs, and herbs) beautify our urban and rural environments, enrich the quality of human life, and represent a vital component of the horticultural industry. The introduction of novel plant varieties and cultivars is critical to the ornamental horticultural industry . To develop ornamental plants with desirable traits, different approaches, such as ploidy manipulation, interspecific hybridization, and physical/chemical mutagenesis, have been used for decades [2, 3]. However, the breeding of new ornamental varieties of trees and shrubs is a time- and labor-consuming process, because these plants may have a long juvenile growth period, large physical size, or altered floral structures, and consequently require long-term observations, large areas for progeny testing, and/or special equipment for pollination and/or seed collection .
