In the past, plant geneticists tried to make use of radiation- or chemically-induced mutations, but the respective low frequencies and occurrence of many recessive and loss-of-function mutations failed to convince breeders of the value of these techniques. In addition, in the era of

Alternative recombination and selection methods have also been developed. On the other hand, there has been a growing concern for conservation a
