| Application of concentrated metabolites of Bacillus subtilis - CMBS - (5,000 µg/mL) one and 24 h before or after inoculation of Sphaerotheca fuliginea (3 x 104 conidia/mL) reduced the number of lesions on cucumber leaves by 90-99%. The average number of lesions on control plants was 16.7 per leaf. A wettable powder product formulated with cells (10%) and metabolites (10%) of B. subtilis (WPBS), and CMBS sprayed on cucumber plants (1,000 µg/mL and 10,000 µg/mL) twice a week totally controlled powdery mildew. In the control treatment, 18 days after the first spray, the percent leaf surface covered by lesions was 99.0 and 46.7%, on the cotyledonary and expanded leaves, respectively. In the control treatment, 30 days after the first spray, the percent leaf... |

| Only a small percentage of seeds arisen by irradiated pollen include haploid embryo. Inspecting the seeds one by one for rescuing the embryos is a tedious and time consuming work which decreases haploid production efficiency in this method for cucurbit plants. Cucumber seeds formed three weeks after pollination with irradiated pollen were floated in liquid medium for about 10 days before excision of the embryos. This innovative method allowed a better development of haploid embryos; they turned to green and germinate like normal seeds and could be identified easily without the need of inspecting the seeds one by one. This method permitted an easier detection and extraction of embryos in comparison with common approach, increased the number and the quality... |

| First record of larvae of Allograpta exotica Wiedemann (Diptera, Syrphidae) preying on Aphis gossypii Glover (Hemiptera, Aphididae) in watermelon in Brazil. Brazil is one of the largest world producers of watermelon (Citrullus lanatus Thumb. Mansf.) and Aphis gossypii Glover, 1877 (Hemiptera, Aphididae) is among the most important pest on this crop. Larvae of Allograpta exotica Wiedemann, 1830 (Diptera, Syrphidae) were found preying on A. gossypii in watermelon crop, in Santa Maria, Rio Grande do Sul State, what represents the first report of this tritrophic association in Brazil. |

| Development of hybrids in bitter melon is expensive because of hand pollination but the utilisation of gynoecy is economical and easier for exploiting hybrid vigour in bitter melon. A study was conducted to determine magnitude of heterosis in bitter melon by making crosses on one gynoecious line, DBGY-201 with eight other inbreds. It was observed that all the hybrids showed significant heterosis in desirable directions for traits like sex ratio, days to first picking, fruit weight, length and girth, yield per plant and vine length. The gynoecious hybrid DBGY-201 × ‘Pusa Vishesh’ showed highest heterosis (-19 %) for earliness and the hybrid DBGY- 201 × ‘Priya’ was reported to provide maximum heterosis for fruit length, weight and yield. These gynoecious... |

| Field survey of the cucurbit crops revealed a high incidence of Cucumber green mottle mosaic virus (CGMMV) in Khyber Pakhtunkhwa Province (KPK), Pakistan. Among the seven districts surveyed, average percent incidence of CGMMV was recorded up to 58.1% in district Nowshera, followed by 51.1% in district Charsada, 40.5% in district Swabi and 37.3% in district Mardan. In Swat and Dir districts average incidence CGMMV was recorded upto 31.2% and 29.4%, respectively. Among the different crops highest incidence in plain areas of KPK was recorded in bottle gourd (59.3%) followed by 56.3% in Squash, 54.5% in Pumpkin, 45.5% in Melon, 41.7% in Cucumber and 29.9% in Sponge gourd. In Northern hilly areas highest incidence of CGMMV (52.9%) was observed in pumpkin,... |

| Watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] is a major cucurbit crop that accounted for 7.5 % of the world area devoted to vegetable production in 2003. Potyviruses are a major limiting factor in commercial watermelon production worldwide. The major viruses affecting watermelon are Papaya ringspot viruswatermelon strain (PRSV-W), Watermelon mosaic virus (WMV), and Zucchini yellow mosaic virus (ZYMV). Sources of resistance to PRSV-W have been reported. These were PI (plant introduction) accessions from South Africa (PI 244017, PI 244018, PI 244019), from Zimbabwe (PI 482342, PI 482318, PI 482379), from Botswana (PI 485583), and from Nigeria (PI 595203). A single recessive gene controls resistance to PRSV-W, with the gene symbol prv.... |

| Citrullus lanatus var. citroides (African melon) is a crop cultivated in sub- Saharan Africa for its dried seeds reported to be rich in nutrients. In this project the relationship between its mode of reproduction and its genetic diversity will be established. This relationship is particularly interesting as C. lanatus var. citroides has been evolving in a traditional farming system, under a low-anthropic selection. On the one hand, the accurate reproduction strategies of this species will be determined by studying the floral morphology, occurrence of autoincompatibility, rate of allogamy. On the other hand, the genetic structure inside different accessions, and the associated population genetic flow will be established. This genetic structure of the... |
