The Genus Collinsia. I. Chromosome Number and Chiasma Frequency of Species in the Two Sections

Meiotic Analysis in Some Varieties of <i>Lens culinaris</i>

“…This was also shown by Garber (1956) in Collisna, Stebbins (1971) in Gramineae and Grant (1958) in Gilia.…”

Identification of Chromosomes Involved in Six Radiation-induced Translocations in <i>Collinsia heterophylla</i>: A Search for the “Pseudo-supernumerary” Chromosome

“…Procedures for germinating the seeds, raising the plants in the greenhouse, fixing young flower buds, for making acetocarmine squash preparation of the pollen mother cells and for making the appropriate crosses were the same as described by Garber (1956), and Rai and Garber (1960).…”

“…This is the only chromosome which has not undergone breakage and therefore any reunion during the revolutionary history of the genus (Garber 1960(Garber , 1963. This chromosome has several features similar to the typical supernumerary or accessory chromosomes e.g.…”

“…Nevertheless, the chromosomes have undergone con siderable structural repatterning, chiefly in the form of reciprocal translocations and paracentric inversions. These two types of chromosomal rearrangements have played a major role in the speciation of this genus (Garber 1960).…”

“…Based on indirect evidence, one of the chromosomes in the genome of C. hetero phylla has been designated "pseudo-supernumerary" (Garber 1963(Garber , 1964. This is the only chromosome which has not undergone breakage and therefore any reunion during the revolutionary history of the genus (Garber 1960(Garber , 1963.…”
