During 1971 and 1972 further progress in the identification of the Ne-genotype of wheat varieties has been made . Many data have been published in literature . Especially Russian workers identified many varieties. The picture formerly given for the distribution of Ne-genes remained unaltered . The

โฆ Synopsis
New data about the geographical distribution of necrosis genes support the previous conclusion, viz. the Old World can be divided by a rough line running through the Mediterranean and Black Sea countries to Lake Baikal and from these to northern Japan. The Ne,-area lies south and east and the Ne, area north and west of this line. There are indications that Ne,-carrying wheat varieties exist in the Leningrad district.
The third supplement contains 441 varieties and selections of which the genotype for hybrid necrosis is given. The total number of tested varieties etc. is now 1150.

Male sterile "lines" are being made carrying either Ne ss or Nets in homozygous condition. The "lines" will be used to determine the necrosis genotype of wheat varieties and at the same time to trace genes restoring fertility in cytoplasmic sterile "lines" . It is suggested that hybrid necrosis cou
