Origin and Breeding
Controlled pollination: ‘PBA Twilight’ (tested as 01-230-5 and later OZP0601) was
identified by the PBA field pea team and is derived from a line bred at Horsham,
VICDPI from a targeted crossing and selection program to improve yield reliability in
low rainfall cropping regions. The final cross made in 2001 (01-230) included the late
flowering variety ‘Kaspa’ and a high yielding, erect growing, very early flowering
parental line PS1537. A pedigree selection program was used to develop the variety.
The line was reselected from an F2 segregating population in 2002 (01-230-5). It was
later selected from a progeny testing experiment in 2003 and promoted consecutively
for yield evaluation from 2004 to 2008. It was promoted to National Variety testing in
2006 as OZP0601. Seed increase commenced in 2006 for variety release from 200
single plant derived lines. ‘PBA Twilight’ produces plants with a medium plant height
and with no leaflets on the tendril (e.g. like ‘Kaspa’). Plant height will vary with
growing conditions. The flower wing is typically pinkish in colour and the colour of
standard is typically minor. The intensity of flower colour can be very minor or appear
absent or be more intense and appear dark pink to purple with stripes. Propagation:
Seed. Breeder: Tony Leonforte, DPI- Horsham, VIC.
