The evaluation revealed significant differences between the hybrids and local rice types across various parameters. None of the varieties exhibited complete resistance to BLB, BS, or GD diseases. However, three varieties (CH3, CH9, and CH11) demonstrated moderate resistance (MR) to BLB. CH11 showed moderate resistance to BS, whereas CH3 and CH9 were moderately susceptible (MS). For GD, three genotypes (CH5, CH6, and CH7) were found to be susceptible (S) compared to the other genotypes. In terms of paddy yield, CH12 and CH13 recorded higher yields (10447 kg ha-1 and 10064 kg ha-1, respectively) than the other hybrids and varieties. While conventional rice types had moderate disease incidence and severity, exhibited the lowest yield and yield-contributing characteristics compared to hybrid varieties.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen El presente estudio tiene como objetivo evaluar trece genotipos de arroz, que comprenden siete variedades importadas y seis locales, junto con el cultivo de control IR24 (originario de China, RRI Kala-Shah-Kaku e ICI, Pakistán), para la resistencia al tizón bacteriano de la hoja (BLB), mancha marrón (BS) y decoloración del grano (GD), bajo condiciones de inoculación artificial en campo. La evaluación reveló diferencias significativas entre los híbridos y los tipos de arroz locales en varios parámetros. Ninguna de las variedades presentó resistencia completa a las enfermedades BLB, BS o GD. Sin embargo, tres variedades (CH3, CH9 y CH11) demostraron resistencia moderada (MR) a BLB. CH11 mostró resistencia moderada a BS, mientras que CH3 y CH9 fueron moderadamente susceptibles (MS). Para GD, tres genotipos (CH5, CH6 y CH7) resultaron ser susceptibles (S) en comparación con los otros genotipos. En cuanto al rendimiento del arroz, los cultivos CH12 y CH13 registraron rendimientos superiores (10 447 kg ha-1 y 10 064 kg ha-1, respectivamente) a los demás híbridos y variedades. Si bien los tipos de arroz convencionales presentaron incidencia y severidad moderadas de enfermedades, mostraron menor rendimiento y características que contribuyen a ese mismo rendimiento, en comparación con las variedades híbridas.]]></p></abstract>
