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...
متن کاملInheritance 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...

to the amount of root growth under the various conditions. At the termination of the experiment nearly all the nematodes were found within the tomato roots. T h e numbers found outside the root were somewhat greater at low light intensity than at high light intensity, particularly at the high inoculum level. Roots produced at the low light intensity were probably insufficient to support the hig...
متن کاملOrigin 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...
متن کاملLycopene and Citrulline Contents in Watermelon (Citrullus lanatus)
Lycopene and citrulline contents of 9 diploids (2X) and their artificially induced autotetraploids (4X) and autotriploids (3X) were determined in mature fruit. Changes in lycopene and citrulline during fruit development was studied using fruit of variety XYXA with three different ploidy levels from 15 to 40 days after pollination (DAP). Polyploids, especially triploids, had higher levels of lyc...
