“…Our model of conducting evaluations for 2 years at three sites brings rigor to the experiment, which facilitates publishing results in refereed journals. Thus far, six refereed articles from this program have been published [6][7][8][9][10][11], with two more in the pipeline. Additionally, recommendations have been disseminated through various extension channels, including articles and presentations at local and regional meetings and webinars.…”

“…Common objectives of cultivar evaluations include updating recommendations and identifying top and/or poor performing cultivars [5]. The objective of our program has been to provide farmers in Pennsylvania and the mid-Atlantic region with recommendations for top-yielding cultivars, primarily in conventional systems [6][7][8][9][10][11]; although, performance in organic systems has also been evaluated [10]. Additionally, we have measured some produce quality attributes.…”

Cultivar selection is an important managerial task for commercial farmers. Numerous available options provide marketing opportunities for farmers; however, they can also make cultivar selection time-consuming. For the past 13 years, a team of Penn State Extension educators and university faculty has implemented a new model to evaluate cultivars for key vegetable crops to assist farmers. Our approach started by building relationships within the vegetable industry with farmers, seed company representatives, and farmer-driven organizations who support our program with funding and gift-in-kind donations. We also added rigor to cultivar evaluations by conducting trials of key vegetable crops over 2 years at three locations. The results were used to develop cultivar recommendations, which were disseminated through various face-to-face and distance Extension avenues. The results were also published in refereed journals. The combination of funding, Extension products, and refereed articles led to university support. A drawback to our approach was the difficulty implementing uniform production methods at three experimental sites. The input of a statistical consultant assisted with overcoming this drawback. This model also required the use of strategies common to successful teams. Our methods are described here for those who desire to build a similar program.

“…Through their research and extension programs, land-grant universities provide farmers an unbiased evaluation of cultivars and allied technologies, such as vegetable grafting. A reliable evaluation requires conducting field evaluations at multiple locations representative of the commercial production area, possibly repeated over a minimum of two seasons, while following the standard agronomic practices used by local farmers [15][16][17][18][19]. Using such protocols, it is possible to compare open-pollinated, hybrid, and/or grafted cultivars by measuring plant characteristics, yield performances, and/or quality of the harvested products, which are the main parameters farmers use for assessing the suitability of a cultivar or rootstock for their farms.…”

Fruit Yield and Physicochemical Quality Evaluation of Hybrid and Grafted Field-Grown Muskmelon in Pennsylvania

et al. 2021

Selecting vegetable cultivars suitable to local environmental conditions and with quality traits desired by the evolving market and consumer needs is an important production decision farmers face annually. As seed companies continue to expand their offerings of new cultivars and rootstocks, selecting the best cultivar and/or scion/rootstock combination can be challenging for farmers. Land-grant universities, through their integrated research and extension programs, can provide an unbiased, science-based evaluation of the available cultivar and rootstock options to assist farmers in making this important selection. A two-year study was conducted to evaluate 20 hybrid cultivars and two grafted entries of muskmelons at three locations in Pennsylvania in 2018 and 2019 to provide farmers with science-based recommendations focused on fruit yield and physicochemical quality characteristics. Most cultivars did not differ in fruit yields from the standard “Aphrodite”. “Sugar Cube” produced more, smaller sized melons than “Aphrodite”. However, the combination of the soluble solids concentration, flesh pH, and titratable acidity values was not as favorable, indicating that consumer preference may be lower for “Sugar Cube” than for other cultivars. Yield from grafted entries was not different from the non-grafted “Aphrodite”; although, biotic and abiotic stressors favoring the use of grafting were not present throughout the study. Physicochemical evaluation of the combination of “Aphrodite” scion and “Flexifort” rootstock was more favorable than “Aphrodite/RS841” and non-grafted “Aphrodite”. This combination may be desirable even in the absence of yield stressors.

In 2011, total marketable yield, fruit size, and number of lobes; fruit discoloration due to silvering; and plant structure were compared among eight commercial green bell pepper (Capsicum annuum) varieties and four breeding lines at three field sites in central New York. Tolerance to phytophthora blight (Phytophthora capsici) was also assessed at one of these sites. No wilting or plant death due to phytophthora blight was observed on the four breeding lines. ‘Paladin’, ‘Intruder’, and ‘Aristotle’ had the highest levels of tolerance to phytophthora blight, among the commercial varieties and maintained their yields in the presence of disease. In the absence of phytophthora blight, yields from these three varieties were comparable to susceptible varieties, but fruit tended to be smaller, and incidence of silvering was high in ‘Paladin’ and ‘Intruder’. Less silvering was observed on ‘Aristotle’ fruit. Total marketable yields from the breeding lines and percent of fruit with four lobes was comparable to the commercial varieties, and some breeding lines also had a low incidence of silvering, but fruit were smaller and set later in the season. Overall, this study suggests that ‘Paladin’, ‘Intruder’, and ‘Aristotle’ will yield well in fields with a history of severe phytophthora blight, but new large-fruited varieties with low incidence of silvering and good tolerance to phytophthora blight are needed.
