New advances of wheat mutation breeding in Heilongjiang Province

Technical Report:

Abstract

Five wheat varieties have been released between 1980 and 1990, these varieties possess early maturity, high yield, good quality, disease resistance and wide adaptability. They have been cultivated on 373 330 ha. Some of them are proved to be very valuable germ plasma for cross breeding. Technique of induced wheat mutation have been studied. Since selecting adaptable irradiation conditions, using combination of radiation with hybridization, irradiating male gamete, female gamete and zygote, soaking treatment with KH+2{sup 32}PO{sub 4}, etc., the efficiency of induced mutation have been increased. By combining radiation with distant hybridization, F{sub 0} unfruitfulness and F{sub 1} sterility have been overcome, and 21 wheat-rye translocation lines have been selected. One of them, 6BS/6RL translocation line, which is called Longfumai No. 4, was released in 1987. The procedure of inducting and identifying translocation lines has been raised already. Mature embryos, anthers and young embryos of wheat were irradiated and inoculated as explants. The rude toxin of Bipoloris sorokiniana, as a screening factor, was added to different medi and finally 3 lines with resistance to Bipoloris sorokiniana were selected. It was established that technical system for in-vitro radiation induced mutation and screening wheat mutants of resistance to disease. The biochemical  More>>
