Cytological Studies on Chromosome Morphology in the Wichita Hard Red Winter Wheat Variety by Means of Monosomic Stocks
Abstract
With the discovery of chromosomes by the end of the past century, numerous workers have from time to time attempted to study their morphology. According to Darlington (1956): "The chromosomes provide us with the record of the past, a living record, significant in a surprisingly simi- lar way to the dead record which fossils provide for the paleontologist." During the past forty years, efforts have been made to identify wheatchromosomes by their morphological characteristics. Early investigations have provided some interesting information, but there was very little success in the identification of individual chromosomes. The measurements in this early work were made on root-tip chromosomes and the identity of the chromosome being measured was not known. With the development of monosomic lines (Sears 1954), in which one member of a chromosome pair is lacking, it became possible to observe the chromosome morphology of the identified univalent at meiosis.
