Inbreeding depression in plant breeding
WebNov 28, 2016 · The challenge for contemporary plant breeding is to not only integrate new traits into our crops, but to accelerate the genetic gain of its breeding programs at the same time, in order to achieve a doubling in speed of yield increase. ... Even though inbreeding depression is severe in perennial ryegrass DHs, reports of vigorous and fertile ... WebThe disadvantage of inbreeding is that it reduces variation in a population and can even result in the accumulation of deleterious alleles, a phenomenon known as inbreeding depression. Some plant species have both outcrossing and selfing flowers, a breeding system known as allautogamy .
