A series of leaf mutants in Gossypium hirsutum L. was tested for allelism and linkage, and three closely linked loci were established on chromosome 15. One locus is represented by a single mutant allele, crinkled leaf (crcr), and the other two loci are represented by a multiple allelic series. The two loci with the multiple allelic series were designated as strap leaf and veins-fused. Alleles of the strap leaf locus are rugose (srsr), Lubbock-1 (slsl), strap leaf (ss), norma(SS), and Heritable Abnormality-3 (ShSh). Alleles of the veins-fused locus are veins-fused (vfvf), normal (VfVf), and Heritable Abnormality-1 (VfhVfh).From independent two and three-point linkage data, we generated a calculated four-locus linkage map as follows: cr-O.20.s-l.20-vf-4.90-Lg [Lg = Green lint] The seven mutants tested all affect leaf development. Each of the three distinct loci appeared to function differently in leaf development and differentiation in cotton.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
