Some agronomic and quality characteristics of new rice varieties in the aegean region of Turkey

In this study, agronomic and quality performances of new rice genotypes were investigated in 2003 and 2004. 12 rice genotypes were used as genetic material. The experiment was conducted in a Randomized Complete Blocks Design with 3 replications under continuous flood irrigation. Based on the means of two years, the highest yield (732 kg/da) and the highest spikelet number per plant (562 spikelet /per plant) were obtained from Osmancık-97. The highest productive tiller number per plant was obtained from Demir (9,6 tiller/ plant), the highest 1.000-grain weight was obtained from Baldo (38 g) followed by Kıral (36.5 g), Kargı (36.2 g) and Negiş (34.5 g) respectively. The shortest plant height was obtained from Toag92 (63 cm). The lowest of days to flowering time was obtained from Toag92 (63 days). The longest panicle was obtained from Troyhikary/Arborio//Nucleoryza and Toyhikary/Solnecnyi genotypes (16 cm) whereas the highest grain length was obtained from Baldo, Demir, Kargı and Gönen (6.9 mm). Also the highest grain width was obtained from Baldo, Negiş and Gönen (2.9 mm). The highest amylose content was obtained from Demir (22.2 %) and the highest crude protein content was obtained from Toag92 (12.4%).
