Resistance in Triticum and Aegilops spp. to Meloidogyne chitwoodi.
Two lines of Aegilops squarrosa (G 3489 and G 1279) and Triticum cultivars Anza, Cocorit, Produra, Chinese Spring, Nugaines, and a synthetic hexaploid were screened for resistance to Meloidogyne chitwoodi. Reproduction of M. chitwoodi, expressed as eggs per gram root, was low (P < 0.01) on G 3489 and the synthetic hexaploid. Reproduction on all other cultivars tested was high although differenc...
متن کاملReproduction of Mi-Virulent Meloidogyne incognita Isolates on Lycopersicon spp.
Selection of detectable numbers of Mi-virulent root-knot nematodes has necessitated a greater understanding of nematode responses to new sources of resistance. During the course of this research, we compared the reproduction of four geographically distinct Mi-virulent root-knot nematode isolates on three resistant accessions of Lycopersicon peruvianum. Each accession carried a different resista...
متن کاملResistance of 14 accessions/cultivars of Lycopersicon spp. to two-spotted spider mite, Tetranychus urticae (Acari: Tetranychidae), in laboratory and greenhouse
مقاومت چهارده رقم و لاین از گونه‌های مختلف جنس Lycopersicon نسبت به کنه‌ی تارتن دو‌لکه‌ای، Tetranychus urticae Koch، در آزمایشگاه و گلخانه بررسی شد. مطالعات آزمایشگاهی بر اساس دو روش زیست‌سنجی پونز (thumbtack) و دیسک برگی (leaf disk) صورت گرفت. گونه‌های Lycopersicon hirsutum و L. pennelii بیش‌ترین تعداد کنه روی پونز را داشتند. بیش‌ترین تعداد تخم (48/0 ± 15/5 تخم بر ماده در روز) رویL. pimpin...
متن کاملResistance to Meloidogyne arenaria in Arachis spp. Germplasm.
Field and greenhouse evaluations of 116 wild Arachis spp. genotypes demonstrated the presence of resistance to reproduction of the root-knot nematode Meloidogyne arenaria race 1. Resistance in greenhouse tests was based on test lines having </= 2.5% of the number of eggs per gram of roots as did the susceptible A. hypogaea cv. Tamnut 74. In field tests, resistant genotypes were identified on th...
متن کاملevaluation of cultivated and wild tomato genotypes (solanum lycopersicum) and (solanum spp.) for resistance to egyptian broomrape (orobanche aegyptiaca)
orobanche aegyptiaca, commonly known as egyptian broomrape, is a holo-parasite that causes high economic damages on tomato production in iran. breeding for resistance is the most economic and feasible method to reduce broomrape infestation. 20 tomato cultivars and four wild tomato species were screened for o. aegyptiaca resistance. tomato yield reduction, dry weight reduction of shoot and root,...
