Inheritance of chlorophyll deficiency traits in lettuce
Article Abstract:
The inheritance, epistatic effects, and linkages of 6 chlorophyll deficient mutants of lettuce is studied. Chlorophyll-deficient-3, -4, -5, -6, -7 and dappled influence the development of the genetic map for lettuce. Chlorophyll-deficient-5 and -6 are epistatic to chlorophyll-deficient-7. Chlorophyll-deficient-3 is epistatic to light green and is recessive. Dappled is a recessive allele. Chlorophyll-deficient-4 is linked to an anthocyanin gene.

Inheritance of dwarfing genes in Lactuca sativa L
Article Abstract:
A diallele study, using hypocotyl elongation assay, of nine dwarf mutants from an M2 population of Lactuca sativa L. to evaluate stem elongation control in lettuce reveals the presence of four dwarfing loci, dwf-1 to 4. The mutants exhibit a reduction in stem length, smaller size and altered flower morphology. Allele dwf-2 induces the expression of dwf-4. The height of dwarf phenotypes ranges between 3 and 30 cm.

Mapping morphological genes relative to molecular markers in lettuce (Lactuca sativa L.)
Article Abstract:
Research on morphological traits traced through reaction-based molecular markers (RAPDs) showed most could be mapped after crossing two experimental lines of lettuce. Ten morphological traits were identified, and 9 were linked to RAPD loci while the tenth remained unlinked. The relative orders of multiple segregating loci and distances were largely conserved in genomic regions.
