Rapid identification of Triticeae genotypes from single seeds using the polymerase chain reaction.

An easy and quick protocol has been developed for DNA analysis via PCR. Single cereal endosperm or small leaf pieces can be separately processed in several PCR reactions. The resultant PCR patterns are equivalent to those obtained with standard DNA extraction protocols using either specific or random primers. Intra- and inter-specific variability can be detected. This method allows the analysis of a large number of individuals in early stages prior to the plant sowing.

High mutability in rye (Secale cereale L.).

Analysis of the rye cultivar Ailés of several descents derived from crosses between plants carrying specific genotypes and/or chromosome constitutions resulted in the detection of high chromosome (2.05 x 10(-2)) and gene (9.3 x 10(-3)) mutation frequencies. The existence of a transposon system responsible for this instability is suggested.
