Abstract
Chromosome analysis of the root tips of Glycine max (L.) Merrill variety T219 revealed several aberrations. Chromosome stickiness, reductional groupings and multiple spindles (as well as multipolar spindles) were observed. In our previous work, we had observed the expression of homozygous genotypes on the heterozygous background in the form of small spots on the leaves of this variety. This paper tends to correlate the two findings. The appearance of some of the spots on the leaves is attributed to the loss of one or more chromosomes, besides somatic crossing-over.
