Abstract

Giza 201 and Giza 202, new barley (Hordeum vulgar L.) cultivars released by Barley Research Department, Field Crops Research Institute, Agricultural Research Center, Egypt in 2021, offers barley growers a new choice for high yielding, high quality of malt and disease resistant cultivars.  The pedigree of Giza 201 is: Carina/WI2291/5/Soufara-02/3/RM1508/ Por//WI2269/4/WI2197/ and forGiza 202 is; Azzaf/Msel. Six yield trials were conducted during the two successive growing seasons; 2018/2019, 2019/2020, and 6 verification yield trials through the growing season 2020/2021. Results of the preliminary yield trial at Sakha and Gemmeiza Agricultural Research Stations indicate that the new barley cultivars Giza 201 and Giza 202 out yielded the checks mean of Giza 128 and Grace at 2018/2019 growing season.  The results of the advanced yield trials over the four locations (Sakha, Gemmeiza, Sids and New valley Agricultural Research Stations) in 2019/2020 season cleared that the new cultivars Giza 201 and Giza 202 out yielded the check cultivar Giza 128 and Grace over all locations.  In 2018/2019 season, at Sakha location the productivity was in favor by 12.34% and 15.85% for Giza 201 and Giza 202, respectively. While at Gemmeiza location the productivity was in favor by 17.89% and 14.22% for Giza 201 and Giza 202, respectively comparing to the check cultivars mean. In 2019/2020 season, comparing with the check cultivars mean, the grain yield productivity of Giza 201 was in favor by 17.38, 10.96, 12.98 and 15.82% at Sakha, Gemmeiza, Sids and New Valley regions, respectively. Also, the new released cultivar Giza 202 surpassed the mean yield of check cultivars at Sakha, Gemmeiza, Sids and New Valley regions by 19.12%, 8.84, 10.29 and 19.55%, respectively.  The results obtained from 6 on-farm trials in 2020/2021 season showed the superiority of Giza 201 and Giza 202 by 14.40 and 12.57%, respectively as average of all locations.  The new released variety was resistant to common barley diseases in all seasons and most locations. Also, the two new cultivars showed suitable values for studied quality traits (protein content, grain size and malt extract yield fine dry basis %) compared to the check cultivar Giza 128. Therefore, Barley Research Department recommends the two new cultivars for their superiority in yield and quality traits to meet the needs of barley growers and industry.
