تنوع ژنتیکی برخی جمعیت‌هایهندوانه (Citrullus lanatus var. lanatus) بر اساس صفات مورفولوژیک و نشانگرهای ریزماهواره(ISSR)

Inheritance of Resistance to Powdery Mildew Race 2 in Citrullus lanatus var. lanatus

Information on the mode of inheritance of powdery mildew resistance in watermelon is important for designing a breeding strategy for the development of new cultivars. Resistance in the watermelon accession PI 270545 was investigated by generation means analysis by crossing it with susceptible PI 267677. The analyses showed involvement of two genes, a recessive resistance gene, pmr-1, and a domi...

ارزیابی تنوع ژنتیکی برخی ژنوتیپ های بومی هندوانه ایرانی (citrullus lanatus var. lanatus) با استفاده از ویژگی های مورفولوژیک و نشانگرهای مولکولی issr

هندوانه درحال حاضر در سراسر جهان به عنوان یک صیفی با ارزش کشت می شود. با توجه به اینکه تنوع ژنتیکی هندوانه های بومی ایران با استفاده نشانگرهای مولکولی (issr) بررسی نشده لذا به منظور بررسی تنوع ژنتیکی تعدادی از ژنوتیپ های بومی هندوانه ایرانی (citrullus lanatus var. lanatus) 17 ژنوتیپ هندوانه شامل 5 رقم بومی منطقه سیستان، 11 توده بومی سایر مناطق ایران و 1 رقم تجاری به نام ساکاتا مورد آزمایش قرار ...

Origin and emergence of the sweet dessert watermelon, Citrullus lanatus.

BACKGROUND AND AIMS Watermelons, Citrullus species (Cucurbitaceae), are native to Africa and have been cultivated since ancient times. The fruit flesh of wild watermelons is watery, but typically hard-textured, pale-coloured and bland or bitter. The familiar sweet dessert watermelons, C. lanatus, featuring non-bitter, tender, well-coloured flesh, have a narrow genetic base, suggesting that they...

Characterization of Watermelon ( Citrullus lanatus var . citroides ) Germplasm for Resistance to Root - knot Nematodes

Root-knot nematodes (Meloidogyne spp.) cause extensive damage to watermelon ICitrz,llus lanatus (Thunb.) Matsum. & Nakai var. lanatusl, and resistance to rootknot nematodes has not been identified in any watermelon cultivar. Twenty-six U.S. Plant Introductions (Pis) of Citrullus lanatus (Thunb.) Matsum. & Nakai var. citroides (L. H. Bailey) Mansf., one P1 of C. lanatus var. lanatus, and three P...

First report on laxative activity of Citrullus lanatus

This study was aimed to assess the possible laxative effect of aqueous fruit pulp extract of Citrullus lanatus in albino’s Wistar rats. Rats were divided in 5 groups of 6 animals each, first group as control, second group served as standard (sodium picosulfate) while group 3, 4 and 5 were treated with fruit pulp aqueous fruit pulp extract of Citrullus lanatus at doses of 250, 500 and 1000 mg/kg...
