The acronym MAGIC that stands for ‘multiparent advanced generation intercross’ is a powerful next generation mapping population to precisely map the agronomically important quantitative trait loci. An eight parent based soybean MAGIC population was developed by employing 2-way, 4-way and 8-way intercross hybridization. The aim was to obtain MAGIC-derived breeding lines with higher yield, broader genetic base, increased diversity and variability. The 8-way and 4-way intercross hybrids so developed in the present study will be evaluated for their yield potential in the subsequent generation under changing climatic conditions (F2–F8 generation).Keywords
High-Throughput Genotyping, Quantitative Trait, Multiparent, 8-Way Hybrids.Full Text

In agriculture, conventional breeding takes a longer time for the development of crop varieties with a minimum of 810 years of breeding cycles. In the context of breeding, rapid generation advancement of segregating populations towards reaching homozygosity will facilitate genetic gain for key traits and the rapid development of improved cultivars. Extra-terrestrial experiments by NASA, USA, to grow crop seeds in space inspired scientists in the University of Queensland and University of Sydney in Australia to develop a speed-breeding platform. Speed breeding uses an artificial environment with enhanced light duration to create longer daylight regimes to speed up the breeding cycles of photoinsensitive crops.Full Text
