| Abstract | ||
| The new super rice variety, Sakha Super 302 is the first Egyptian Japonica Green Super. Rice (EJGSR), a high yielding and early maturing. This variety was developed by the breeder of the national project program to develop the production of hybrid and super rice under conditions of water scarcity and climate change and his team, sponsored by the Field Crops Research Institute (FCRI), Agricultural Research Center (ARC), and the Academy of Scientific Research and Technology (ASRT), in the Arab Republic of Egypt. The variety Sakha Super 302, was developed from crossbreeding between innovative lines PTGMS 19 x EJSR 26 in 2009, then it was developed by selection using the pedigree method and confirmed in 2016 from the F7 generation with the name of the line EJGSR 176. Preliminary, advanced, on-farm trails, DUS and VCU tests in 2017 to 2023 indicated high yield, short duration (115-120 day) and favorite agronomic and grain characteristics. The variety Sakha Super 302 was registered in accordance with ministerial resolution no. 108 issued in March 2023. The average grain yield was recorded in yield trails, on-farm experiments and farmers extension trails for Sakha Super 302 and checks varieties, Giza 177, Sakha 101, Sakha 104, Sakha 108 and Sakha Super 300 during 2019 to 2023 were 10.899, 9.375, 10.353, 9.926, 10.537 and 11.508 t/ha, respectively. Thus, the yield of Sakha Super 302 exceeded those of the checks, Giza 177, Sakha 101, Sakha 104 and Sakha 108 by 16.25%, 5.27%, 9.70% and 3.43%, respectively. On the other hand, Sakha super 302 exhibited the highest productivity for grain yield per day 91.93 kg/day/ha compared to 75.03kg, 73.69kg, 73.71kg and 76.54 kg for Giza 177, Sakha 101, Sakha 104 and Sakha 108, respectively, furthermore, it saved water consumption where it consumed 1186m3/ha with water use efficiency (WUE) of 0.974 compared to Giza 177 that consumed about 12850m3/ha with (WUE) of 0.730. Both rice varieties, Sakha Super 300 and Sakha super 302, gave better grain yields when planted early before May 15 and late after that date, and were significantly superior to the traditional check varieties, Giza 177, Sakha 101, Sakha 104 and Sakha 108. The new rice variety, Sakha super 302 showed better grain quality attributes compared with Giza 177, Sakha 101, Sakha 104 and Sakha 108. Altogether with high yield potential and other agronomic performance, it is expected to have a good rank among commercial rice varieties. Tests conducted at plant protection program proved that the new super rice variety Sakha super 302 is resistant to blast and moderately resistant to stem borer. | ||
