Abstract

The National Subterranean Clover Improvement Programme (NSCIP) aims to develop, by breeding and selection, better adapted and more productive low—oestrogen cultivars of subterranean clover for a range of environments in southern Australia. The programme is a collaborative one with the University of Western Australia and consists of two phases: (i) early generation selection, which involves selecting varieties satisfying primary selection criteria; and (ii) field evaluation of advanced lines, which is conducted by the Departments of Agriculture in each State and co—ordinated by the Plant Breeder.

The first phase is conducted at the University Field Station (UFS) and is continued until the F7 or F8 generation, while the latter consists of 2 or 3 stages, each lasting 2-3 years.

1. Field evaluation in Western Australia of breeding lines from the National Subterranean clover improvement programme.

Trial 89V18

Location: Vasse Research Station

Seventeen early—midseason ssp. yanninicum breeding lines, comprising nine crossbreds and one introduction from the NSCIP programme and seven crossbred lines from the South Australian Department of Agriculture, two ssp. yanninicum cultivars (Trikkala and Larisa), one late—midseason ssp. subterraneum introduction (CPI 89816F) and one nil control. Seed of crossbred lines known to contain low levels of Cucumber Mosaic Virus.

Trial 89W4

Location; Wokalup Research Station, Paddock 48

Seventeen early-midseason ssp. yanninicum breeding lines, comprising nine crossbreds and one introduction from the NSCIP programme and seven crossbred lines from the South Australian Department of Agriculture, two ssp. yanninicum cultivars (Trikkala and Larisa), three midseason ssp. subterraneum cultivars (Junee, Seaton Park and ICarridale) and two late-midseason varieties currently undergoing registration as new cultivars (CPI 89774F and CPI 89830F). Trial details:
