Karyologie der GattungSecale L.

Abstract: W~hrend die Systematik des Roggens, besonders in letzter Zeit, ziemlich genau ausgearbeitet ist, sind zytologische Daten sehr sp~rlich.Der erste, der Roggenchromosomen gez~hlt hat, war Nem~c (1910); er fand in den triploidon Zellen der Endospermanlage yon Secede cereale L. 18 Chromosomen, was haploid der Zahl 6 entsprechen wtirde. Nakao (1911) z~hlte in der heterotypischen Kernplatte der Pollenmutterzellen yon Secede cereede 8 Chromosomen. S a k a m u r a (1918) land 7 haploide Chromosomen. Durch die Untersueh… Show more

“…The first chromosome counts are those of Nemec (1910) as cited by Emme (1928), giving 18 chromosomes for endosperm cells. Other reports (Westigate, see Stolze, 1925) and Spiliman (cf.…”

“…According to FERRAND (1923), ocasional nondisjunction of one the seven bivalents gave rise to plants with an extra pair whereas cells with even higher numbers could arise by fragmentation at some stage. Still the haploid number remained uncertain until a number of careful mitotic and meiotic counts along with the analyses of extra chromosomes, established 7 as the correct one (STOLZE, 1925;AASE and POWERS, 1926;THOMPSON, 1926;EMME, 1927;LEWITSKY, 1929LEWITSKY, , 1931and others) and higher numbers of 8,9, or 10 being for the strains carrying B-chomosomes (EMME, 1928;DARLINGTON, 1933;HASEGAWA, 1934;POPOFF, 1939;MUNTZING, 1944,etseq. ).…”

“…B chromosomes occur in a low frequency in several lines of S. cereale and in a few populations of S. strictum subsp. strictum (Emme 1928;Darlington 1933;Hasegawa 1934;Popoff 1939;Müntzing 1944Müntzing , 1950Kranz 1963;Jones and Rees 1982;Niwa et al 1990).…”
