Using the random amplified polymorphic DNA (RAPD) method, the genetic diversity of 19 Greek landraces and 9 cultivars of durum wheat [Triticum turgidum L. var. durum (Desf.)] was studied. Two commercial bread wheat (Triticum aestivum L.) cultivars and one genotype of Triticum monococcum L. were also included in the study. Eighty-seven arbitrary primers (10-mer) were evaluated in a preliminary experiment and 15 of them were selected for the main experiments based on the quality and reliability of their amplification and the polymorphism they revealed. A total of 150 DNA bands were obtained, 125 (83.3%) of which were polymorphic. On average, 10 DNA bands were amplified per primer, 8.3 of which were polymorphic. The genetic similarity between all pairs of genotypes was evaluated using the Jaccard’s or Nei and Li’s coefficients; the values of the former ranged from 0.153 to 0.973 while those of the latter were slightly higher (0.265–0.986). Cluster analysis was conducted by the UPGMA and the Njoin methods. Both methods broadly placed 26 durum genotypes into 1 branch while the other branch consisted of 2 subgroups: 1 included the 2 bread wheat cultivars; the other 1 consisted of 2 durum landraces, ‘Kontopouli’ and ‘Mavrotheri-Chios’, which showed an intruiging behaviour sharing bands with the bread wheat cultivars. The T. monococcum cultivar stood apart from all other genotypes.

The effect of previous crops (oilseed, legume, and cereal) on the incidence and severity of crown rot (Fusarium pseudograminearum, Fp) and yield of wheat was investigated in 3 field studies in northern New South Wales. The experiments were designed to compare the effectiveness of the Brassica break crops canola (Brassica napus L.) and mustard (B. juncea L.) with chickpea (Cicer arietinum L.) on reduction of Fp in subsequent wheat crops. Responses to previous broadleaf and cereal crops were investigated in Fp-tolerant bread wheat (Triticum aestivum L.) and Fp-susceptible durum wheat [Triticum turgidum L. ssp. durum (Dest.)]. In all experiments, broadleaf break crops increased the yield of Fp-susceptible durum wheat compared with durum after cereals (by 0.24–0.89 t/ha). The same response was observed for the Fp-tolerant wheat at 2 of the 3 sites (0.71 and 0.78 t/ha), with a lower yield (0.13 t/ha) after break crops than after cereals at one site during a drought. The yield of the Fp-susceptible durum wheat was generally higher after brassicas than after chickpea (yield advantage 0.27–0.58�t/ha), whereas there was no such difference in the tolerant wheat variety. In most cases, these yield responses to the previous crops were closely related to the severity of Fp infection. Overall yield of susceptible durum wheat was reduced by 1% for each 1% increase in Fp severity at harvest. Residual water and nitrogen (N) did not explain responses to previous crops, although common root rot (Bipolaris sorokiniana) may have contributed to some of the responses at the sites. There was little evidence that the lower disease and higher yield following brassicas compared with chickpea was related to suppression of Fp by biofumigation. More plausible explanations are that residual cereal residues decomposed more rapidly under dense Brassica canopies thus reducing Fp inoculum, that Fp severity was increased following chickpea due to higher soil N status, or that brassicas resulted in soil/residue biology that was less conducive to Fp inoculum survival. Evidence for the latter was provided by consistently higher levels of Trichoderma spp. isolated from wheat following brassicas compared with chickpea or cereals. Irrespective of the mechanisms involved, the results demonstrate that Brassica oilseeds provide an effective break crop for crown rot in northern NSW. Furthermore, brassicas may provide an excellent alternative rotation crop to chickpea for high value durum wheat due to an apparent capacity to more effectively reduce the severity of crown rot infection in subsequent crops.
