Narrative
Dwarf parental line near-isogenic to RHA 271. An oilseed restorer with genes for fertility restoration of the PET1 cytoplasmic male sterility. Height 64.2 +- 5.0 cm, compared with 119.6 +- 7.4 cm for RHA 271. Exhibits a head diameter of 8.2 +- 1.1 cm, a stem diameter of 1.8 +- 0.3 cm, and 21.4 +- l.1 leaves per plant, which is not significantly different from RHA 271. Since similar number of leaves per plant as RHA 271, reduced stature is produced by shortened internodes. Similar to RHA 271 for head angle and level of autogamy. In combination with standard-height parental lines, produces semi-dwarf hybrids. Semi-dwarf hybrids exhibit a reduction of about 25 to 30% in stature in comparison with near-isogenic standard-height hybrids. Under dryland conditons in Southern Spain, semi-dwarf hybrids presented similar yield potential than standard-height hybrids. Higher yield potential for semi-dwarf hybrids is expected in high yield environments and under conditions that promote lodging or stem breakage. In combination with its isoline RHA 271, are also an excellent material for basic and applied research on plant dwaftism.

Pedigree
Description:
Developed by introgressing genes for reduced plant height from the dwarf line Donsky (Yugoslavia) into the oilseed restorer parental line RHA 271 (PI 599786). After the initial cross, F1 plants (semi-dwarf), were backcrossed to the recurrent parent RHA 271. In each backcross generation, semi-dwarf heterozygotes were identified and backcrossed to the recurrent parent. Released as BC5F6-derived BC5F7 parental line.
