Linkage Tests in Upland Cotton, <i>Gossypium hirsutum</i> L. II.¹

Results of linkage analyses of cotton performed at College Station, Texas are presented, and linkage information reported by other workers is summarized. The mutants withering bract, accessory involucre, abnormal palisades, Ragged Leaf, round leaf, Red Dwarf, male‐sterile‐1, male‐sterile‐2, Male‐sterile‐4, and Ligon Lintless were tested for linkage with several marker loci and in various combinations among themselves. Ragged Leaf and round leaf were found to be linked (R.C. = 32 %), and thus form a new linkage group, number X. Data are presented to document the simple dominant inheritance of Ligon Lintless; the symbol Li is assigned to the mutant allele.
