Comment
The chromosome with Lr19 in Indis is probably identical to that in Agatha {1162}. 7DL = T7DS.7DL-7Ae#1-7DL {388}. v: Mutant 235 {681}. 7AL = T7A-7Ae#1 {330}. v: Sears' 7A-7Ag No.12 {330} 7BL {1163}. v: 88M22-149 {1163}; 4 further derivatives of 88M22-149 {0232} 7AgL {1304} = 7Ae#1L. su: Agrus. ma: Co-seg with 8 RFLP markers {048}; Ep-D1c - 0.33 cM - Lr19 {1587}; cosegregation with Ep-D1d {974}; Prins et al {1162} studied 29 deletion mutants in Indis and determined the gene order: Sd-1 - Xpsr105-7D- Xpsr129-7D - Lr19 - Wsp-D1 - Sr25 - Y; The following gene order for the Thinopyrum segment is given in {0101}; Cent - Sd1 - Xpsr165-7D - Xpsr105-7D -Xpsr129-7D - XcslH81-1 - Xwg380-7D - Xmwg2062-7D - Lr19 - Wsp-D1 - Sr25/Y; An STS marker closely linked and distal to Lr19 was developed from an AFLP {0273}. Lr19 is usually associated with Sr25. Sears' transfer 7D-7Ag No. 11 carries neither Lr19 nor Sr25. See Lr29. Knott {681} obtained two mutants (28 and 235) of Agatha possessing Lr19, but with reduced levels of yellow pigment in the flour. Marais {890,892} obtained mutants and recombined lines with intermediate levels of, or no, yellow pigment. It was shown that recombinant line 88M22-149 lacked yellow pigment {1163}. Secondary translocation line I-96 derived from Sears' 7D-7Ag no.1 involved Lr19 being located in an intercalary segment with low yellow pigment and lacking Sd1 {10255}. Lr19 in lines I-22 and I-23 retaining yellow pigment but lacking Sd1 was transferred to durum chromosome 7BL {10255}. One of the lines with the shortest 7Ag segment, Lr19-I49-299, was used in a further cycle of recombination {10278}.
