Selection for resistance to colletotrichum trifolii in the lucerne medicago sativa cultivars hunter river and siro peruvian






Australian Journal of Experimental Agriculture & Animal Husbandry 20(105): 447-451

Selection for resistance to colletotrichum trifolii in the lucerne medicago sativa cultivars hunter river and siro peruvian

Seedlings of lucerne (M. sativa) with increased resistance to anthracnose caused by C. trifolii, were obtained from 'Hunter River' and 'Siro Peruvian' by selection through 2 generations under laboratory conditions. Glasshouse screening of half sib F1 and F2 families confirmed that rapid progress was made in increasing the level of resistance in both populations. In the field, after 2 yr, F1 derivatives had lower percentages of plant mortality and disease indices than their parent cultivars, and F2 derivatives had lower values than their F1 parents. The F2 population of 'Siro Peruvian' in the 2nd yr, yielded 55 and 45% more dry matter than the unselected populations of 'Siro Peruvian' and 'Hunter River', respectively. However, the level of resistance in the field of the 'Siro Peruvian' F2 population was only the equivalent of the unselected 'Hunter River' population, and was inferior to the F1 and F2 populations of 'Hunter River'.
