Summary
Several near-isogenic lines of durum wheat cv. LD222 have been developed. These include a near-isogenic line carrying gene P and designated P-LD222. The P gene from Triticum polonicum determines a long empty outer glume. The objective of this study was to determine the inheritance and chromosomal location of the P gene. To determine the inheritance, P-LD222 was crossed to two chlorina mutants and to a near-isogenic line for the purple culm trait, Pc-LD222. Linkage of the P gene with the mutated gene in chlorina mutant CDd6 indicated that the P gene was located on chromosome 7A. P-LD222 was also crossed with durum cultivar Langdon (LDN) and the LDN D genome substitution lines, LDN 7D(7A) and LDN 7D(7B). Segregation for the long glume trait in the F2 of LDN/P-LD222 and LDN 7D(7B)/P-LD222 was normal (3:1) and indicated P gene was not on chromosome 7B. Significant deviation from a 3:1 in the F2 of LDN 7D(7A)/P-LD222 confirmed the location of P on chromosome 7A, as indicated by the linkage analysis.
