In an eight-replication characterization test at Stuttgart in 1997, LGRU ef was 26 d earlier and 3 cm shorter than its parent.
In 11 tests between 1999 and 2002, LGRU ef yielded 5400 kg [ha.sup.-1], flowered in 75 d, was 109 cm tall, and showed 29% lodging.
The breeding value of LGRU ef may be limited by the yield penalties observed in most tests although the mutant should be tested in different genetic backgrounds by crossing with other materials (MacKay, 1984).
Apparent amylose content of LGRU ef was similar to the parent cultivar LGRU (210-230 g [kg.sup.-1]), as was the intermediate alkali spreading value.
In the 1997 characterization test, LGRU 13 was 83 cm tall, or 22 cm shorter, and 3 d earlier than its parent.
Apparent amylose contents of the KBNT, LGRU, and ADAR mutants were similar to those of the parent cultivars (210-230 g [kg.sup-1]), and amylose content of the ORIN mutant was similar to that of its parent (130-150 g [kg.sup.-1]).
