Common Mating Design for Hybrid Development

Temesgen Begna, Workissa Yali

The most important design used in plant breeding to produce progeny is the mating design. Plant breeders and geneticists use a number of mating techniques to achieve their goals. The choice of a proper mating design is crucial for plant breeding success. Plant breeders experimented with various mating designs and arrangements in order to produce progenies. With the major aims of gathering genetic information and producing plant cultivars to obtain the base population, mating designs play a critical role. The choice of mating pattern and genetic resources are crucial in conventional crop enhancement programs. Several factors influence mating design selection, including time, space, study aims, and other relevant issues. The analysis of variance gives a quick and easy way to understand the many types of mating designs. In general, combining ability is important in estimating genetic components and selecting appropriate parents and hybrids to increase crop output. The capacity to combine traits is crucial in determining the breeding strategy to develop desired qualities There is a chance to improve parents through selection when the general combining ability to specific combining ability is greater than unity, and when the general combining ability to specific combining ability is less than unity, the breeding procedure is designed to improve desirable traits through heterosis breeding. To develop agricultural development programs, gene activities are examined and studied utilizing various mating patterns as genetic expressions. To improve the required desirable features, hybridization with the use of mating is very important to widen the genetic bases of the population.
