Since 1918, when KIHARA began his genetic research on wheat and its related genera, a great numbers of species and varieties, including Triticum, Aegilops, Secale, Agropyron and Haynaldia, have been collected from all over the worid. They have been maintained by the financial support of the Ministry of Education.
The numbers of collected species, strains and also artificially induced autopolyploids and amphidiploids, are as follows:
The collected stocks have been maintained by selfing from generation to generation. One of the difficulties of maintaining these stocks has been that the flowering time of most of them coincides with the rainy season in Kyoto. For this reason some of the valuable stocks of diploid species were often lost and had to be replaced. In compliance with requests we shall be able to supply the seeds obtained by open pollination of all but some diploid species of Aegilops.
Ae. squarrosa L. var. Meyeri Griseb. and var. anaihera Eig and also ssp. strangulata Eig are missing from our collection and we would appreciate any contribution to complete our stock.
