Abstract
Three surveys of direct market (pick-your-own) strawberry customers were conducted in Illinois to obtain demographic information, distance travelled, purchase habitude, and advertising response. A mail survey utilizing postcard reminders resulted in a higher number of returned forms than 2 anonymous handout surveys without follow-up. The rates of return were influenced by follow-up cards, the time interval of mailing the follow-up cards, and the growers’ personal request to their customers to complete survey forms. The survey methods are discussed relative to the large numbers of completed surveys required in our research and the applicability of various survey methods for direct marketing.
Abstract
Customer harvest (PYO) of research plots at University of Illinois and University of Arkansas research stations began in the late 1960s when it became difficult to harvest extensive research plots. Similar methods were developed independently for customer harvest at both locations. Initially we invited faculty, staff, their wives, and eventually other local people to pick strawberries, blackberries, and blueberries. We obtained yield records and the customers paid for the fruit. Data were collected to evaluate cultivars and advanced breeding selections of strawberries, blueberries, and blackberries.
Abstract
The genetic variability of 20 cultivars of horseradish, Armoracia rusticana Gaertn., Mey., & Scherb., was measured and classified. These cultivars were chosen from a gene pool containing over 400 cultivars, and collectively they appeared to represent the extreme and intermediate forms of variability found in horseradish. Two methods of classification were compared. One classification was based on 2 highly diagnostic characters that showed the extreme and intermediate limits of the germplasm in the form of a scatter diagram. The other classification was based on 40 characters. For this classification methods of numerical taxonomy were used to show the germplasm complex by scatter diagrams and phenograms. The two classifications appeared to be equal in defining the extreme limits of the genetic variability. The main area of disagreement was found among the relative positions of the intermediate forms or genotypes. The use of scatter diagrams as an aid to the selection and conservation of genetic variability for future use is discussed.
Abstract
In a broad sense, fresh-market vegetable corns include all maize harvested and eaten fresh while the kernels are tender and before all of the sugars are converted to starch. This definition includes “roasting ears” of selected field corns that lack sweetness-enhancing genotypes and are considered “starchy”. Traditionally, however, sweet corn cultivars have been homozygous for the recessive sugary (su) gene (8).
