Crop alteration and biotechnology

Crop alteration has been practiced by humankind for thousands of years, since the UT28F256QLET-45UCC beginning of civilization. Altering crops through breeding practices changes the genetic make-up of a plant to develop crops with more beneficial characteristics for humans, hm8370fp for example, larger fruits or seeds, drought-tolerance, or resistance to pests. Significant advances in plant breeding ensued after the work of geneticist Gregor Mendel. His work on dominant and recessive alleles gave plant breeders AP9960M a better understanding of genetics and brought great insights to the techniques utilized by plant breeders. Crop breeding includes techniques such as plant selection with desirable traits, self-pollination and cross-pollination, and molecular techniques that genetically ATS302T modify the organism.Domestication of plants has, over the centuries increased yield, improved disease resistance and drought tolerance, eased harvest and improved the taste and nutritional value of crop plants. Careful selection and breeding have had enormous effects on the characteristics ta7063p of crop plants. Plant selection and breeding in the 1920s and 1930s improved pasture in New Zealand. Extensive X-ray an ultraviolet induced mutagenesis efforts during the 1950s produced the modern commercial varieties of grains such as wheat, corn and barley.
