Abstract
Sugar beet has been commercially introduced in Egypt since 1982 with cultivated area about 20,000 feddans and increased gradually to be 25,7667 fed. in 2008. The plan is to increase the sugar beet area and beet sugar factories to fill the gap between sugar consumption and production which reaches about one million tons a broadly imported every year. Recently, reclaimed desert irrigated lands at West Nubariya and El-Bostan regions has shown that sugar beet can be successfully grown under sandy soil area condition and it's considered as the extended area for sugar beet production in Egypt. The root-knot nematode, (Meloidogyne incognita and M.-javanica), is the most serious problem against sugar beet expansion in the new arable lands which was reported as major nematode pests of sugar beet in Egypt. The present study was carried out during the growing season 2007 - 2008 at pots experiment in Sabahia Agricultural Research Station, Alexandria, Egypt, for evaluating the reaction of twenty seven sugar beet genotypes against the most serious nematode, (Meloidogyne javanica). The twenty seven sugar beet genotypes used in this test were 21 commercial varieties and 6 breeding materials.
Computed damage index classified the twenty seven sugar beet genotypes into four categories one commercial variety was highly susceptible (HS), nine genotypes were susceptible (S), thirteen genotypes moderate resistant (MR), and four genotypes resistant (R), three of them are commercial varieties while the best one in computed damage index was proven to be the breeding material (Eg.27).
