Why do polyploid hybrids have a high
economic value?
Answers
Answer:
Biological invasions are a major ecological and socio-economic problem in many parts of the world. Despite an explosion of research in recent decades, much remains to be understood about why some species become invasive whereas others do not. Recently, polyploidy (whole genome duplication) has been proposed as an important determinant of invasiveness in plants. Genome duplication has played a major role in plant evolution and can drastically alter a plant's genetic make-up, morphology, physiology and ecology within only one or a few generations. This may allow some polyploids to succeed in strongly fluctuating environments and/or effectively colonize new habitats and, thus, increase their potential to be invasive.

Answer:
Some of the most important consequences of polyploidy for plant breeding are the increment in plant organs (“gigas” effect), buffering of deleterious mutations, increased heterozygosity, and heterosis (hybrid vigor).
