Abstract
Based on the experiences in wheat breeding of the past 60 years (1954 ~2013), the author would like to share the following views with the readers. First, wheat production is determined by the demand of the market. Second, it is the key to success in breeding program to base the strategy on the requirement of the production and to focus on the drought tolerance, yield potential, multiple resistances and wide adaptability. It always fails without the correct breeding objective. Third, it is important to have the genetic information in yield potential and to keep in line with the development of breeding technologies. The breakthrough in breeding depends on the discovery or development of elite germplasm. Fourth, it is the best way to improve the germplasm, which has high yield potential and a number of undesired traits at the same time, by introgression method usually involving multiple parents. The crossing model should be" good x good" , in which the elite germplasm plays a key role. Fifth, alternative selection of segregated generations in the breeding program between the drought and irrigated environment and between high fertile soil and medium fertile soil have been to be very efficient in the development of the new varieties with drought tolerance, high water use efficiency, high yield potential and wide adaptability. Based on the pedigree analysis of the released varieties, Norin 10 seems to carry the genes for drought tolerance and high yield potential and worth being investigated further.关键词
