Origin and Breeding<br />

Controlled pollination: ‘PBA Gunyah’ (tested as 01-256-10 and later OZP0602) was<br />

identified by the PBA field pea team and is derived from a line bred at Horsham,<br />

VICDPI from a targeted crossing and selection program to improve yield reliability in<br />

low rainfall cropping regions. The final cross made in 2001 (01-256) included a late<br />

flowering breeding line PS1594 and a high yielding, erect growing, very early<br />

flowering breeding line PS1535. A pedigree selection program was used to develop<br />

the variety. The line was reselected from an F2 segregating population in 2002 (01-<br />

256-10). It was later selected from a progeny testing experiment in 2003 and<br />

promoted consecutively for yield evaluation from 2004 to 2008. It was promoted to<br />

National <strong>Variety</strong> testing in 2006 as OZP0602. Seed increase commenced in 2006 for<br />

variety release from 200 single plant derived lines. ‘PBA Gunyah’ produces plants<br />

with a medium plant height and with no leaflets on the tendril (e.g. like ‘Kaspa’). The<br />

flower wing is typically pinkish in colour and the colour of standard is typically<br />

minor. The intensity of flower colour can be very minor or appear absent or be more<br />

intense and appear dark pink to purple with stripes. Propagation: Seed. Breeder: Tony<br />

Leonforte, DPI- Horsham, VIC.<br />
