The correct answer is Option (3) -Wheat Breeding is carried out by conventional breeding techniques or by mutation breeding. The conventional method of breeding for disease resistance is that of hybridisation and selection. It’s steps are essentially identical to those for breeding for any other agronomic characters such as high yield. The various sequential steps are screening germplasm for resistance sources, hybridization of selected parents, selection and evaluation of the hybrids and testing and release of new varieties. Some crop varieties bred by hybridization and selection, for disease resistance to fungi, bacteria and viral diseases are : |
