| Abstract |
A field experiment was carried out at the farm of Rice Research and Training Center (RRTC), Sakha, Kafr El-Shiekh, Egypt, in 2015 and 2016 seasons. The experiment was conducted to estimate the agronomical, technological of seed characteristic and some chemical composition of different rice cultivars namely Giza 178, Giza 179, Sakha101, Sakha104, Sakha105 and Sakha106. The rice cultivars were grown in randomized complete bloke design with three replications. The main results revealed that Giza 178 and Sakha 101 cultivars surpassed all the other tested cultivars and produced the greatest grain yield and its attributes. The tallest plants were observed with Sakha 104 and Sakha 101 cultivars and the longest duration was found with Giza 178, Sakha 101 and Sakha 104 rice cultivars. Concerning seed vigor, there were any significant differences among all tested cultivars in germination percentage. Sakha 104 and Sakha 101 cultivars produced the heaviest 1000-seed weight and the highest electrical conductivity was observed with Sakha 101 and Sakha 104, while Giza 179 gave the greatest seed vigor index. Hulling and milling percentage were the highest in Sakha 104, 105 and 106, while Giza 179 gave the highest head rice. As for cooking characters, results indicated that Giza 178 gave the highest value in water uptake and Giza 179 produced the greatest volume expansion. All the tested cultivars had the same time for cooking time except Giza 179 and Sakha 104 cultivars, which gave the lowest value in this aspect. The two Giza cultivars (178 and 179) plus Sakha 101 had higher amylose content than the other Sakha cultivars under study. Results also indicated that Giza cultivars under study gave the greatest values in protein content, ash and either extract than the tested Sakha cultivars, while the fiber crud percentage reached to the maximum with Sakha 104 and total carbohydrate with Sakha 101 rice cultivars
