Is it really difficult for graduate students majoring in crop genetics and breeding to find jobs?
However, the specific breeding objectives should comprehensively consider the current situation of local varieties, breeding basis, natural environment, farming system, cultivation level, economic conditions and other factors, and constantly adjust with the development of production. It is also necessary to define the direction that needs to be maintained or improved, improved or overcome based on several varieties with large planting area or representative areas in this area, so as to make the breeding objectives specific.
Crop breeding methods are closely related to crop propagation methods. The self-bred crop population is a mixture of some homozygous genotypes, or it may be a single genotype, with small heterogeneity or homogeneity and high genetic homozygosity.
Mixed selection, pure line breeding, cross breeding (mainly interspecific hybridization) and backcross breeding are all suitable for this kind of crops. The ultimate goal is to cultivate highly homozygous varieties. But both of them are self-bred crops, and the breeding methods are not consistent.
