摘要
本文研究了2个箭筈豌豆(Vicia sativa L.)品种333和333/A 的核型.这两个品种中期柴色体的数目,形态及核型相似.它们的核型公式是:K=2n=12=2m+6st(2SAT)+4t,它们之间的区别是:333/A 的第1对柴色体的长臂上有次缢痕.并讨论了该种有关核型多变的问题.
The article deals with karyotypes of 333 and 333/A,2 varieties ofVicia sativa L,Their chromosome numbers and micrographs of somatic meta-phase and karyograms are similar.(see Table 1 and plate 1).Their karyotypeformula is:2n=2x=12=2m+6st(2SAT)+4t.The dliffernce between themis that chromosome 1 of variety 333/A has a secondary constriction onthe long arme of chromosome.The karyotype variations of the speciesand also discussed.
