Abstract
Horticulture crops have traditionally required long-term breeding programmes for the development of new varieties, primarily due to their perennial nature and long juvenile phase. Speed breeding offer a promising solution to accelerate the generation advancement process, resulting in the rapid release of new varieties with desirable traits. This incorporates various breeding methods such as FasTrack breeding using genetically engineered tree flowering genes, tissue culture techniques, marker-assisted selection (MAS), genomic selection and induced mutation breeding. Whereas, strategy related to speed breeding includes various cultural practices such as, grafting, application of plant bio-regulators, soil solarization and utilize dwarfing rootstocks. The shortened breeding cycle facilitated by speed breeding allows for faster release of new fruit varieties and meeting the increasing demand for horticultural products for the growing population. In this article, we will discuss the speed breeding techniques and strategies that play a crucial role in enhancing the efficiency of fruit crop breeding.
