Discovery of microchromosomes in wheat and their special behavior in meiosis
摘要
THERE are 42 chromosomes in common wheat (Triticum aestivum L). The extra microchro-mosomes were discovered in alloplasmic lines of common wheat with cytoplasms of Ae. muti-ca, Secale cereale, Elytrigia elongatum and Agropyron glaucum. The microchromo-somes were discovered in amphiploid of Triticum aestivum-Secale cereale (DDRR) too.
