Abstract

Butternut pumpkin (Cucurbita pepo L.) is an economically important vegetable and summer crop. The seeds have high nutritional value due to their edible oil and protein content with a high medicinal value. Butternut pumpkin is attacked by several fungal diseases one of which is powdery mildew (PM) caused by Podosphaera xanthii. In this study, we analyzed the effect of sowing type and date on 14 local butternut pumpkin genotypes for resistance against powdery mildew. The two different sowing types were greenhouse vs. open field and the two sowing dates were first week of May vs. 3rd week of May 2021–22. The results showed that powdery mildew severity percentage (PMSP) was 42 % in the field #1 sown in the first week of May compared to the field #2 with 48 % severity sown two weeks later than the field #1 indicating 6 % increase in PMSP significantly. On the other hand, PMSP severity in the greenhouse was 55.2 % which was 8–13 % greater than those occurring in the field. There was also a wide variation in disease severity among the genotypes. The highest PMSP was recorded in” Orumiyeh1” (84.8 %) followed by “Maragheh3” (82 %), and the lowest ones were in “Maragheh1” (9.4 %) and “Shahreza” (6.1 %) genotypes. In conclusion, we found that the ideal conditions for cultivating butternut pumpkin with the least PMSP include sowing during the first week of May in field #1 and the use of resistant cultivars such as “Maragheh1” and “Shahreza” as a part of an integrated pest management program.

播型和播期对冬南瓜白粉病互作的影响

冬南瓜（Cucurbita pepo L.）是一种重要的经济蔬菜和夏季作物。由于其食用油和蛋白质含量高，具有很高的药用价值，具有很高的营养价值。冬南瓜受到几种真菌病害的侵袭，其中一种病害是由黄足霉引起的白粉病。本研究分析了播型和播期对14个地方冬南瓜基因型抗白粉病的影响。两种播种类型分别为温室和露天，播种日期分别为2021 - 2022年5月第一周和5月第3周。结果表明，5月第一周播种的1号田比2号田的白粉病严重程度百分比（PMSP）为42%，比1号田晚两周播种的白粉病严重程度百分比为48%，表明PMSP显著增加了6%。温室PMSP严重程度为55.2%，比田间高8 ~ 13个百分点。基因型之间的疾病严重程度也有很大差异。PMSP最高的是“Orumiyeh1”（84.8%），其次是“Maragheh3”（82%），最低的是“Maragheh1”（9.4%）和“Shahreza”（6.1%）。综上所述，我们发现栽培PMSP最低的冬南瓜的理想条件是在5月的第一周播种在1号田，并使用抗病品种如“Maragheh1”和“Shahreza”作为害虫综合治理计划的一部分。

期刊介绍： Ecological Genetics and Genomics publishes ecological studies of broad interest that provide significant insight into ecological interactions or/ and species diversification. New data in these areas are published as research papers, or methods and resource reports that provide novel information on technologies or tools that will be of interest to a broad readership. Complete data sets are shared where appropriate. The journal also provides Reviews, and Perspectives articles, which present commentary on the latest advances published both here and elsewhere, placing such progress in its broader biological context. Topics include: -metagenomics -population genetics/genomics -evolutionary ecology -conservation and molecular adaptation -speciation genetics -environmental and marine genomics -ecological simulation -genomic divergence of organisms
