Compared to conventional crops, less is known about how genetic and environmental variability affect the yield and quality of specialty crops like cranberry (Vaccinium macrocarpon Ait.). Herein, we performed a multifaceted analysis of six commercial cranberry beds planted to the Stevens cultivar. The six beds included three with above‐average multiyear yields and three that were lower than average. We considered genotype, edaphic factors, and plant nutrient content as driving variables of yield and fruit quality. We found that genetic purity within beds raised the odds of obtaining above‐average yields over an 8‐year period. The highest levels of genetic contamination (38%–75%) were found at the low‐yield beds, where significant differences in yield and fruit quality were observed between genotypes, within beds. Across all beds, focusing only on plots genetically confirmed to be Stevens cultivar, we also found that plot‐scale yield in 2020 was significantly higher for two of three high‐yield beds, suggesting other factors besides genetic contamination influenced differences in bed‐scale yield. A factor analysis of mixed data that jointly included genotype, edaphic variables, and plant tissue nutrient content revealed complex relations among these variables that were tied to grouping plots based on long‐term yield. Findings highlight the need for further research into the complex genetic and environmental factors that control cranberry yield and fruit quality.

基因型、土壤因素和植物养分对多年生特种作物产量和果实品质的影响（Vaccinium macrocarpon Ait.）


与传统作物相比，人们对遗传和环境变异如何影响蔓越莓（Vaccinium macrocarpon Ait.）等特种作物的产量和质量知之甚少。在此，我们对种植史蒂文斯品种的六个商业蔓越莓床进行了多方面分析。这六个床位中，三个床位的多年产量高于平均水平，三个床位的多年产量低于平均水平。我们认为基因型、土壤因素和植物养分含量是产量和果实品质的驱动变量。我们发现床内的遗传纯度提高了 8 年期间获得高于平均产量的几率。在低产床中发现了最高水平的遗传污染（38%–75%），在床内不同基因型之间观察到产量和果实品质的显着差异。在所有床位中，仅关注经基因证实为史蒂文斯品种的地块，我们还发现 3 个高产床位中的 2 个床位规模产量在 2020 年显着较高，这表明除遗传污染外的其他因素也影响了床位规模产量的差异。对共同包括基因型、土壤变量和植物组织养分含量的混合数据进行因子分析，揭示了这些变量之间的复杂关系，这些变量与基于长期产量的分组图相关。研究结果强调需要进一步研究控制蔓越莓产量和果实质量的复杂遗传和环境因素。
