| Popis: | The experiment was carried out during growing season (2018-2019) at the Rice Research Station in Mishkhab / AL-Najaf-Iraq, The seeds of 27 genotypes were sowing with the aim of selecting the best economically yielding genotypes for cultivation under the conditions of AL-Najaf. The experiment was arranged with a randomized complete block design with four replication. The results showed significant differences between the genotypes for all the traits under study. The G27 genotype showed superiority for traits exceeded, number of grains per panicle, grain yield ton. ha-1, the biological yield ton. ha-1 and the sterility percentage (%), with averages were 220.17, 13.34, 27.95, and 4.48, respectively. Whereas, the genotype G14 was superior with the characteristics of the number of fertile panicles and the duration of fullness the grain, which averaged 37.00 and 82.25 respectively, while the genotype G13 was significant for weight of 1000 grains (g), and the genotype G21 was superior with the flag leaf area which gave an average 32.45 cm2. Through this study, genotypes (G1, G2, G12, G15, G16, G17, G18, G21, G25 and G27) showed the best field performance in terms of growth characteristics and the outcome of their selection for the second agricultural season. |
