A sequential batch testing procedure was used in conjunction with ELISA or cDNA probes to estimate the incidence of chrysanthemum stunt viroid (CSVd), chrysanthemum carlavirus B (CVB), tomato aspermy cucumovirus (TAV) and tomato spotted wilt tospovirus (TSWV) in chrysanthemum (Dendranthema grandiflora) crops in Australia. A total of 2480 samples of potted,(More)
When germplasm is evaluated over a period of time and a range of environments, there is a danger that the basis of evaluation will change. The extent of such variation in samples from a germplasm collection was assessed using powdery mildew resistance in barley as an example. The changes found are believed to be representative of those commonly encountered(More)
Estimations of random mating frequency were computed for a series of sequential autumn sowings of populations of winter barley. The estimations were by means of the maximum likelihood scoring method and three varieties, each carrying a recessive genetic marker, provided three independent estimations for each population. High levels of out-crossing were(More)
