Abstract BACKGROUND: Wild radish, a problem weed worldwide, is severe dicotyledonous in crops. In Australia, sustained reliance on ALS‐inhibiting herbicides to control this species has led the evolution of many resistant populations endowed by any several ALS mutations. The molecular basis herbicide resistance novel population was studied. RESULTS: gene sequencing revealed previously unreported substitution Tyr for Ala at amino acid position 122 individuals wild radish (WARR30). A purified...

Resistance evaluation for herbicide resistance–endowing acetolactate synthase (ALS) gene mutations using Raphanus raphanistrum populations homozygous specific ALS mutations. Weed Research 52 , 178–186. Summary Acetolactate (ALS)‐inhibiting resistance is common in (wild radish) across the Western Australian (WA) grain belt. This study investigates molecular and biochemical basis of five R. populations. Five known (Pro‐197‐Ala,...

Summary Growth, competitiveness and seed characteristics were compared in paraquat‐resistant ‐susceptible biotypes of Hordeum leporinum Link collected from neighbouring fields. Dry weight tiller production greater the susceptible biotype as with resistant absence competition, however, reproductive output was same. Competitiveness field estimated using a replacement series design that showed only slight differences between two biotypes. There no weight, number seeds per head, viability or...
