| 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, which differ in plant type, time of maturity, productivity and grain quality, in a randomized complete block design, with three replications, in both seasons. 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. On the other hand, 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 it was significantly highest in 100 grain weight, (3.93 and 3.95 g),in the two seasons, respectively. The results, also, indicated in significant differences between the lines No. 3, 4 and 5 in the duration of maturity and they were the significantly earliest. In the two seasons 2023 and 2024, regarding of line No. 2, the results indicated a non-significant increase in total milled rice %. | ||
