Public funding for land-grant university plant breeding programs has declined to the point that alternative sources of funding have had to be identified in order for these programs to continue. Small fruit breeding programs at land-grant universities in the southern region of the U.S. now derive their support for day to day operations from a number of alternative funding sources including commodity organizations and research foundations. Royalty income generated from sale of plants of patented cultivars has also become a significant source of support for essentially all land grant programs. In addition, cooperative agreements and contracts with partners in private industry play a prominent role in support for several programs, and these will likely increase significantly in the near future. At present, U.S. plant patents are generally applied for upon the release of cultivars from small fruit breeding programs at land grant universities in the southern region, with some move toward trademarking. Releases are generally nonexclusive within the region, and either exclusive or nonexclusive outside the region. The use of germplasm from other breeding programs usually carries with it the expectation of mutual exchange and use of germplasm and/or sharing of royalty income from cultivars derived from such germplasm.

In many cases, measurement of cucumber fruit weight in small research plots involves more labor and resources than just counting the number of fruit per plot. Therefore, plant breeders are interested in an efficient method for estimating fruit weight per grade (early, marketable, and cull) based on fruit number and total fruit weight. We evaluated the cucumber germplasm collection of 810 plant introduction accessions (supplied by the U.S. Dept. of Agriculture, Regional Plant Introduction Station at Ames, Iowa) along with seven check cultivars for yield. Correlations were calculated for all pairs of fruit number and fruit weight combinations for each grade. In general, the lowest correlations were observed between the fruit weight of each grade (early, marketable, and cull) and total fruit weight or number per plot. High correlations were observed for fruit weight and fruit number within each grade (early, marketable, and cull). An efficient method for estimating fruit weight per hectare of early, marketable, and cull grades is to count total, early, and cull fruit, then measure total fruit weight. Our results showed that the fruit weight of each grade (early, marketable, and cull) was best estimated using the fruit number of that grade (early, marketable, and cull) along with the total fruit weight and total fruit number.
