Rice in Egypt is one of the most important food crops. Annually,it oqupies about 0.6 million ha., producing about 6.1 million tons of paddy with national average reaches 9.4 tons/ha which considered among the highest per unit area productivity of the rice producing countries in the world. Rice grain quality comes second to high yielding ability in rice breeding objectives in the national rice improvement program in Egypt. The importance of grain quality is needed to cover the local and exotic consumer requirements. Annually, a sum of abut 0.65 million tons of milled rice are exported.These requirements concentrated mainly on short grain, bold grain shape (Length/weidth ratio), fully translucent, high milling out-turn with low brocken percentages and low amylose content. Recently,some new special rices with special characteristics such as aromatic rice and black rice were considered to cover some market demands. Breeding for grain quality in rice is very difficult for many reasons.In spite of these difficulties,considerable progress has been made in combining in modern Egyptian rice varieties good grain quality and high yield potential. Hybridization breeding method followed by appropriate selection procedure (mostly pedigree method) has been routinely and commonly used by the national rice rice breeding program. Annually, about 3500 individual plants and 50-60 bulks (promising lines) are selected according to their earliness,plant type, disease and insects resistance resisrance and mainly grain quality characteristics.
