Intergenic ribosomal spacer variability in hexaploid oat cultivars and landraces


The variability of the ribosomal DNA intergenic spacer (IGS) was analysed in 58 cultivars from a worldwide collection and 14 Spanish landraces of hexaploid oats. IGS sequences were amplified by the polymerase chain reaction using primers complementary to conserved sequences of the ribosomal genes. Twelve IGS length variants ranging from 4090 to 3210 bp were… (More)
