Summer Squash

Yellow and zucchini squash (Cucurbita pepo L.) cultigens (breeding lines and cultivars) were evaluated over a 2-year (1995 and 1996) period in North Carolina. Yellow squash cultigens that performed well (based on total marketable yields) were `Destiny III', `Freedom III', `Multipik', XPHT 1815, and `Liberator III' in Fall 1995 and HMX 4716, `Superpik', PSX 391, `Monet', `Dixie', XPH 1780, and `Picasso' in Spring 1996. Some of the yellow squash cultigens evaluated had superior viral resistance: XPHT 1815, XPHT 1817, `Freedom III', `Destiny III', `Freedom II', TW 941121, `Prelude II', and `Liberator III' in Fall 1995 and XPHT 1815, `Liberator III', `Prelude II', and `Destiny III' in Fall 1996; all these cultigens were transgenic. The yellow squash cultigens that performed well (based on total marketable yields) in the Fall 1995 test had transgenic virus resistance (`Destiny III', `Freedom III', XPHT 1815, and `Liberator III') or had the Py gene present in its genetic background (`Multipik'). Based on total marketable yields, the best zucchini cultigens were XPHT 1800, `Tigress', XPHT 1814, `Dividend' (ZS 19), `Elite', and `Noblesse' in Fall 1995; and `Leonardo', `Tigress', `Hurricane', `Elite', and `Noblesse' in Spring 1996. The zucchini cultigens with virus resistance were TW 940966, XPHT 1814, and XPHT 1800 in Fall 1995 and XPHT 1800, XPHT 1776, XPHT 1777, XPHT 1814, and XPHT 1784 in Fall 1996. Even though TW 940966 had a high level of resistance in the Fall 1995 test, it was not as high yielding as some of the more susceptible lines. Viruses detected in the field were papaya ringspot virus (PRSV) and watermelon mosaic virus (WMV) for Fall 1995; while PRSV, zucchini yellow mosaic virus (ZYMV), and WMV were detected for Fall 1996. Summer squash cultigens transgenic for WMV and ZYMV have potential to improve yield, especially during the fall when viruses are more prevalent. Most transgenic cultigens do not possess resistance to PRSV, except XPHT 1815 and XPHT 1817. Papaya ringspot virus was present in the squash tests during the fall of both years. Thus, PRSV resistance must be transferred to the transgenic cultigens before summer squash can be grown during the fall season without the risk of yield loss due to viruses.

Os vírus representam sérios obstáculos para o sucesso da olericultura no mundo inteiro, constituindo a identificação daqueles de maior incidência numa região, papel fundamental para o estabelecimento de estratégias de controle. Visitas de campo foram realizadas a plantios de espécies de cucurbitáceas em áreas produtoras do Maranhão e amostras foliares foram coletadas de 118 plantas com sintomas ou suspeita de sintomas de vírus, sendo 46 de abóbora (Cucurbita moschata), 30 de melancia (Citrullus lanatus), 23 de maxixe (Cucumis anguria), 13 de pepino (C. sativus) e seis de melão (C. melo). Todas as amostras foram testadas contra anti-soros específicos para os principais vírus das famílias Bromoviridae, Comoviridae e Potyviridae que infetam cucurbitáceas no Nordeste, mediante "enzyme-linked immunosorbent assay" (ELISA) indireto e dupla difusão em agar. Os resultados revelaram a identificação sorológica de Papaya ringspot vírus (PRSV) em 64,4% das amostras analisadas, seguido de Watermelon mosaic virus-2 (WMV-2) em 15,2%, Cucumber mosaic virus (CMV) em 6,8%, Squash mosaic virus (SqMV) em 3,4% e Zucchini yellow mosaic virus (ZYMV) em 3,4%. Este levantamento confirma a predominância do PRSV em espécies de cucurbitáceas cultivadas no estado do Maranhão.

Field information about viruses infecting crops is fundamental for understanding the severity of the effects they cause in plants. To determine the status of cucurbit viruses, surveys were conducted for three consecutive years (2016–2018) in different agricultural districts of Oklahoma. A total of 1331 leaf samples from >90 fields were randomly collected from both symptomatic and asymptomatic cucurbit plants across 11 counties. All samples were tested with the dot-immunobinding assay (DIBA) against the antisera of 10 known viruses. Samples infected with papaya ringspot virus (PRSV-W), watermelon mosaic virus (WMV), zucchini yellow mosaic virus (ZYMV), and cucurbit aphid-borne-yellows virus (CABYV) were also tested by RT-PCR. Of the 10 viruses, PRSV-W was the most widespread, with an overall prevalence of 59.1%, present in all 11 counties, followed by ZYMV (27.6%), in 10 counties, and WMV (20.7%), in seven counties, while the remaining viruses were present sporadically with low incidence. Approximately 42% of the infected samples were positive, with more than one virus indicating a high proportion of mixed infections. CABYV was detected for the first time in Oklahoma, and the phylogenetic analysis of the first complete genome sequence of a CABYV isolate (BL-4) from the US showed a close relationship with Asian isolates.

The Impact

Despite the importance of field-grown cucurbits in Spain, only limited information is available about the impact of disease on their production. During the 2003 and 2004 growing seasons, systematic surveys were carried out in open field melon (Cucumis melo) and squash (Cucurbita pepo) crops of Murcia Province (Spain). The fields were chosen with no previous information regarding their sanitation status, and samples were taken from plants showing viruslike symptoms. Samples were analyzed using molecular hybridization to detect Beet pseudo-yellows virus (BPYV), Cucurbit aphid-borne yellows virus (CABYV), Cucumber mosaic virus (CMV), Cucumber vein yellowing virus (CVYV), Cucurbit yellow stunting disorder virus (CYSDV), Melon necrotic spot virus (MNSV), Papaya ringspot virus (PRSV), Watermelon mosaic virus (WMV), and Zucchini yellow mosaic virus (ZYMV). We collected 924 samples from 48 field plots. Out of these, almost 90% were infected by at least one of the viruses considered, usually CABYV, which was present in 83 and 66% of the melon and squash samples, respectively. In the case of melon, CYSDV, BPYV, and WMV followed CABYV in relative importance, with frequencies of around 20 to 30%, while in squash, CVYV and BPYY showed frequencies between 28 and 21%. The number of multiple infections was very high, 66 and 56% of the infected samples of melon and squash, respectively, being afflicted. CABYV was present in all multiple infections. The high incidence of CABYV in single and multiple infections suggests that this virus may well become an important threat for cucurbit crops in the region. Restriction fragment length polymorphism (RFLP) analysis revealed that CABYV isolates can be grouped into two genetic types, both of which seemed to be present during the 2003 epidemic episode, but only one of the types was found in 2004.

Breeding Lines

In an effort to develop bottle gourd (Lagenaria siceraria) as a widely adapted rootstock for watermelon grafting, we sought to identify lines with broad resistance to several cucurbit viruses that are economically important in the United States. Preliminary analysis under greenhouse conditions indicated that the currently available commercial watermelon rootstocks were either highly susceptible or somewhat tolerant to one or more viruses. However, in greenhouse screening, several breeding lines of bottle gourd displayed broad-spectrum resistance to four viruses tested, including Zucchini yellow mosaic virus, Watermelon mosaic virus (WMV), Papaya ringspot virus watermelon strain (PRSV-W), and Squash vein yellowing virus. Resistance to PRSV-W and WMV was confirmed through field trials in two consecutive years at two different locations in South Carolina. Two breeding lines (USVL#1-8 and USVL#5-5) with broad-spectrum virus resistance could be useful materials for watermelon rootstock development.

Siraitia Grosvenorii

Luohanguo, Siraitia grosvenorii (Swingle) C. Jeffrey, is a perennial cucurbitaceous plant that is an economically important medicinal and sweetener crop in Guangxi province, China. Surveys conducted during the summer to fall seasons of 2003-2004 in northern Guangxi showed symptoms typical of a viral disease, including leaf mottling, mosaic, vein clearing, curling, and shoestring-like distortion in the field. Mechanical inoculation of sap from leaves of symptomatic plants collected from the surveyed areas caused similar symptoms on tissue culture-derived healthy Luohanguo plants. Two sequences of 0.7 and 1.6 kb with 88 and 97% identity to Papaya ringspot virus (PRSV) and Zucchini yellow mosaic virus (ZYMV) were amplified using reverse transcription-polymerase chain reaction (RT-PCR) with purified flexuous viral particles or total RNA extracted from the symptomatic Luohanguo leaves as templates with conserved degenerate potyvirus primers (1). To confirm the results, primers specific for PRSV (PP1/PP2, genome coordinates 4064-4083/5087-5069, GenBank Accession No X97251) and ZYMV (ZP1/ZP2, genome coordinates 5540-5557/7937-7920, GenBank Accession No L31350) were used to perform RT-PCR from the same RNA templates. The expected 1.0- and 2.3-kb fragments were amplified and they were 90 and 95% identical to PRSV and ZYMV in sequence, respectively. Watermelon mosaic virus was not detected. To our knowledge, this is the first report of the occurrence of PRSV and ZYMV in Luohanguo. Reference: (1) A. Gibbs et al. J. Virol. Methods 63:9, 1997.
