Abstract

Rice grains of ten rice varieties namely, Giza177, Giza 178, Sakha 101, Sakha 102, Sakha 104, Sakha 106, Giza 182, Yasmine, Sk2034(H1), and SK2046 (H2) were provided by Rice Research Program, Field Crop Research Institute, Agriculture Research Center, Sakha, Kafr El-Sheikh,  Egypt during 2018 and 2019 growing seasons. The experiment was laid out as split – plot design in a randomized complete block design (RCBD) with three replicates. The main – plot was devoted to tested ten rice varieties while sub – plot devoted to three different methods for rice bran oil extraction (hexane, isopropanol and screw press). The results were recorded on (hexane, isopropanol and screw press) as recorded by SES 2008 , were revealed that,  there are significant difference among  rice cultivars for all the studied characters, except  peroxide  value and free fatty acids%. Comparison between means showed that, Giza 178 variety gave the highest values for crude oil%, total phenolic content, tocotrienols, tocopherols and gama oryzanol in both studied seasons. Furthermore, Yasmin rice cultivar showed the highest values for saponification number in both seasons. The highest iodine value was recorded with Sakha 104 and SK 2034 H1 varieties in 2018 and2019 seasons, respectively. Extraction of rice bran oil by isopropanol showed the highest values for crude oil%, iodine value, total phenolic content, tocotrienols, tocopherols and gama oryzanol in 2018 and 2019 seasons. Interaction between rice cultivars and different methods for extraction of rice bran oil revealed that using Giza 178 variety and extraction of rice bran oil by isopropanol solvent gives the highest values of crude oil %, total phenolic content, tocotrienols ,tocopherols and gama oryzanol in 2018 and 2019 seasons. Correlation coefficient was highly significant and positive between crude oil and tocotrienols highly significant and positive correlation were found among total phenolic and each of tocotrienols, tocopherols and gama oryzanol ,indicated that selection for total phenolic components enhancement each of tocotrienols, tocopherols and gama oryzanol. Finally, using Giza 178 as a donor can improve bran oil content in hybrid rice program.
