《作物育种学总论》试题库(国外英文资料) Examination questions library of Crop Breeding Science Three, judge the problem (correct hit +, wrong to hit -) Introduction 1. Varieties are not botanical, but agricultural. 2. Variety is the smallest taxon in botany. 3, natural evolution and artificial evolution are not only different, but also related. 4, there is a contradiction between artificial selection and natural selection in many aspects of plant evolution. 5, artificial selection is consistent with natural selection in plant evolution. 6. Modern breeding is the science of controlling biological genetic variation and artificial evolution. 7, crop breeding is the science of studying the theory of breeding fine crop varieties. 8, fine varieties generally have regional and temporal, in different regions or the same region at different times, because of the requirements of production and life is different, the requirements of varieties are not the same. Types and types of crop propagation 9, only sexual reproduction can produce seeds. 10, the genetic stability of self pollinated crop varieties depends on the homozygosity of individual genotypes. The genetic stability of 11 crop varieties and cross pollination groups rely on random mating between individuals within the group to maintain. Homozygous genetic stable 12 crop varieties and cross pollination groups rely on individual genotypes to ensure. 13, the self inbreeding of general self pollinated crops was slight, and the inbreeding of inbred crops was strongly degraded. 14, the self inbreeding of general self pollinated crops is strong, and the inbreeding of inbred crops is slight. germplasm resource 15, crop origin centers have two main characteristics, namely, gene diversity and dominant gene frequency are higher. 13, crop origin centers have two main characteristics, namely, gene diversity and recessive gene frequency are higher. 17, storage and preservation are mainly used to control the temperature and humidity conditions during st
