Summary
InPisum sativum tertiary trisomics and trisomic interchange heterozygotes have been derived from Hammarlund’sK-line interchange heterozygote, which has a meiotic association of four chromosomes. The origin of the trisomics is shown to be in numerical non-disjunction of the association of four in one only of the four possible ways.
Eleven different types of trisomic may occur when the two original types are selfed. Progenies of selfed trisomics are described, including one new (primary) trisomic.
The degree of sterility of the trisomics is discussed.
An analysis is made of single-gene ratios expected among trisomics in the progeny of interchange heterozygotes. These ratios provide a means of locating genes in the interchanged chromosomes.
Other trisomics reported inP. sativum are reviewed.
