| Abstract | ||
| Two field experiments were conducted at the Agricultural Research Station, Alexandria University, during the two summer seasons 2023 and 2024. The main objective of the present study was to evaluate five new rice lines 1, 2, 3, 4, 5 and Giza 177 as a control variety in a randomized complete block design, in both seasons. The genotypes differ in plant type, time of maturity, productivity and grain quality. The results indicated that the Line No.1, gave the highest values for grain yield, (10.80 and 10.74 t/ha), number of ear-bearing tillers/ m2(447 and 442 tillers) and amylose content (22.8 and 22.2 %), also it was significantly highest in number of grains per panicle (230 and 216 grains), panicle length (26.50 and 26.30 cm) and protein content (8.30and 8.50 %), in the two seasons, respectively. In the meantime, the line No.5 recorded the highest of grain yield (10.70 and 10.60 t/ha) and number of ear-bearing tillers/ m2 (475 and 469 tillers) and as well it was significantly highest in 100 grain weight (3.93 and 3.95 g), in the two seasons, respectively. The results also revealed that there were significant differences among the lines No. 3, 4, and 5 in the duration of maturity since they were the significantly earliest. Regarding line No. 2, the results indicated a non-significant increase in total milled rice % in the two seasons 2023 and 2024. | ||
