Chromosome numbers were determined for the Rubus species and cultivars held at the USDA/ARS National Clonal Germplasm Repository, Corvallis, Ore. Counts were made on a total of 205 taxa; 81 of which were new, 124 were corrections, and a few were corrections of previous reports. The numbers ranged from 2n = 2x = 14 to 2x = 98, and included odd-ploids and aneuploids. Knowledge of the chromosome number of a plant is important for its use in breeding because of potential sterility problems that may arise due to unbalanced gametes. The value of these particular counts are that they are vouchered by a permanent, living plant collection that is available to the scientific user community.

Students wanting to prepare for a career in public horticulture can now enroll in a new undergraduate and graduate curriculum at the Univ. of Tennessee. Beginning fall semester, 1999, students enrolled in the Dept. of Ornamental Horticulture and Landscape Design (OHLD) can opt to follow the new Public Horticulture concentration in the ornamental horticulture and landscape design major. The Public Horticulture concentration was the result of a year-long curriculum revision that reflects growth in career options in horticulture. The goal of the Public Horticulture concentration is to prepare students for careers that promote horticulture and emphasize people and their education and enjoyment of plants. Such careers include director of a botanical garden, arboretum, or park; city or urban horticulturist; extension agent, teacher, educational director, or program coordinator; professional garden writer/editor or publication manager; horticulture therapist; public garden curator; and plant collections manager. The Public Horticulture concentration allows students to take a breadth of ornamental horticulture courses, five of which are specific to public horticulture, along with supporting course work in soils, entomology, plant pathology, and botany, while providing the opportunity for students to take electives in education, extension, public administration, grant writing, museology, psychology, information sciences, journalism, and management. Students also complete an internship for graduation and have the opportunity to work in the Univ. of Tennessee Inst. of Agriculture Gardens.

The Allen Centennial Gardens are located at the Univ. of Wisconsin–Madison on the grounds of the National Historical site, the house of the first four deans of the College of Agriculture and Life Sciences. The 2.5-acre garden, developed and managed primarily by the Dept. of Horticulture, replaced the old teaching and display garden space taken over in building additions. Within the past 10 years the grounds have been designed and transformed into a garden, with 26 individual collection gardens, including: turf, fruit and vegetable gardens, classic ornamental gardens (with both herbaceous and woody perennials), and a rock alpine garden. As it receives its finishing touches, an education plan is being developed to complement the education purpose of the garden; the goal of the garden is to become an active site for learning through both observation and interaction with the garden collections. The two main themes of the learning experience are: 1) the biology of the diverse and unique plant collections (including: culture, practices, and production), and 2) the aesthetics of the garden (the organization of space, form, topography, and color). Implementation of education programs will occur on the following four levels: first the university (first the horticulture department, second other departments and university functions); second, area high schools groups; third, community and professional groups; and fourth, elementary school groups. The education programs will include mapping, internships, classes, meetings, volunteerism, and tours. The Allen Centennial Gardens, with its education mission, has already and will continue to be a meeting grounds for the university community, and a meetings ground for both the professional community and Madison-area community.
