Cactus pear production has been an outstanding activity during the last two decades in central Mexico. It has been devoted mainly to fresh consumption for the national market and for exporting to the USA to a lesser extent. Official statistics report ≈200,000 ton of fresh fruit entering the market every year from June to September. Such a volume is supported on a limited stock of varieties that were originally selected by growers. They were first cultivated in backyards and now as commercial orchards under rainfed conditions. With the exception of `Reyna', there are no formal descriptions of such varieties. This information will be valuable to growers and could provide a background to define breeding goals and strategies. Data was collected in 1992–94 from 12 of the most important cactus pear varieties in central Mexico. The following traits related with fruit quality we registered: fruit weight and color, peel thickness, seed number, and weight and soluble solids. Average fruit size ranged from only 679 in `Charola' to more than 200 g in `Cristalina' with 2.8 and 5.6 g of seeds/fruit, respectively. Commercially, white fleshed fruit is highly appreciated, but there is a wide range from yellow and orange to deep red. Edible portion ranges from 46% in `Cardona' to 64% in `Centenario', while percent soluble solids showed less variability (13.2–15–9), which seems to be strongly influenced by light and temperature at harvest.

Japanese cedar, Cryptomeria japonica (Thunb. ex L.f.) D. Don [Cupressaceae Bartling, formerly assigned to Taxodiaceae Warm.] is increasing in popularity as a landscape plant in the eastern United States. A taxonomic study of cultivars grown in the eastern United States was conducted. Forty-five cultivars were recognized. Each cultivar bears synonymy, a quantitative morphological description newly described from field data, herbarium vouchers, references to original literature and observational notes. A glossary of taxonomic terms relevant to Cryptomeria is presented. A taxonomic key is presented for segregation of cultivars that should assist professional plantsmen in identification of taxa cultivated in the eastern United States.

Information is presented about the linkages and relationships between the research and the transfer of technology-extension systems established within the countries that compose the Common Market of the South [Mercado Común del Sur (MERCOSUR)]. A brief description about the history of agricultural extension in each country is included along with descriptions of the major changes that have occurred within the last 10 years. This analysis allows a general comparison among the different extension approaches, and in particular regarding the institutional development for the system in the four countries of MERCOSUR.
