Abstract:
... The genetic relationship between acetyl-coenzyme A carboxylase (ACCase; EC 6.4.1.2.) activity and herbicide tolerance was determined for five maize (Zea mays L.) mutants regenerated from tissue cultures selected for tolerance to the ACCase-inhibiting herbicides, sethoxydim and haloxyfop. Herbicide tolerance in each mutant was inherited as a partially dominant, nuclear mutation. Allelism tests indi ...

Abstract:
... To investigate the cost of the dimorphic cyanogenic system in Trifolium repens L., genotypes of the cyanogenic (Tc) and acyanogenic (Ta) morphs were grown in mixtures over a range of ratios and in pure stands at two levels of total density (low in a first experiment, high in a second experiment). The principles of the competition analysis employed were those related to the inverse linear model res ...

Abstract:
... Three main zones of esterase activity (EST-I, EST-III, EST-IV) identified in leaf extracts of cultivated apple and Malus species were determined by the genes EST-1, EST-3 and EST-4, respectively. In addition to earlier reported alleles of EST-1 (a, b) three further bands c, d and f were identified in the Est-1 zone of which c was found to be determined by an allele, c. Two alleles, a, b, and a nul ...

Abstract:
... Salt-tolerant cell lines of citrus rootstock (Poncirus trifoliata cv Pomeroy) were selected by subculturing embryo-derived calli on media containing sublethal concentrations of NaCl (5 and 10 g/l). Selected lines showed a normal growth in the presence of salt at the concentrations used for selection, and salt tolerance persisted after a passage on a salt-free media. Their K+ and Ca2+ content remai ...

Abstract:
... Pollen pool heterogeneity, which violates an assumption of the mixed-mating model, is a major potential problem in measuring plant mating systems. In this study, isozyme markers were used to examine pollen pool heterogeneity in two natural populations of jack pine, Pinus banksiana Lamb., in northwestern Ontario, Canada. Population multilocus estimates of outcrossing rate ranged from 0.83 to 0.95 a ...

Subject:
chickens; animal breeding; selection index; genetic improvement; artificial selection
Abstract:
... When traits become evident at different ages or there are large differences in the costs of measuring various traits, selection by independent culling levels may give a higher aggregate economic return than index selection because not all traits need to be measured on all individuals. The problems with optimum independent culling selection is that general solutions are not possible and numerical i ...
