Development of genetic stocks of sunflower with resistance to sunflower chlorotic mottle virus = Conformación de recursos genéticos de girasol con resistencia al virus del moteado clorótico del girasol
The common race of sunflower chlorotic mottle virus (SCMoV-C) can cause severe yield losses in susceptible genotypes of sunflowers if infection occurs at early plant stages. In Argentina, SCMoV-C is widespread in sunflower production fields and even if its incidence is generally low, in some cases i...

| description | The common race of sunflower chlorotic mottle virus (SCMoV-C) can cause severe yield losses in susceptible genotypes of sunflowers if infection occurs at early plant stages. In Argentina, SCMoV-C is widespread in sunflower production fields and even if its incidence is generally low, in some cases it can reach up to 95%. To date, no complete resistance to SCMoV-C has been detected in commercial cultivars. In the search for resistant germplasm, wild sunflower (Helianthus annuus L.) populations from Argentina were tested, as they were exposed to natural selective pressure during their naturalization. After artificial inoculation with SCMoV-C, symptom-free plants
were selected and grown for controlled self-pollination, sibling crosses and crosses with inbred lines. Recurrent selection for non-symptomatic plants and self-fertility significantly increased the frequency of asymptomatic individuals after SCMoV-C inoculation in the development germplasm. After eight generations of recurrent selection and controlled crosses, four genetic stocks with complete SCMoV-C resistance were developed. |

En los genotipos susceptibles de girasol, la cepa común del Virus del moteado clorótico del girasol (SCMoV-C) puede causar graves pérdidas de rendimiento si la infección ocurre en las primeras etapas del desarrollo de la planta. En Argentina, el SCMoV-C está muy extendido en los campos de producción de girasol y aunque su incidencia es generalmente baja, en algunos casos puede llegar hasta el 95%. Hasta ahora, no se ha detectado resistencia completa a SCMoV-C en cultivares comerciales. En la búsqueda de germoplasma resistente, poblaciones de girasol silvestre (Helianthus annuus L.) de Argentina fueron testeadas, ya que durante su naturalización estuvieron expuestas a presión selectiva natural. Después de la inoculación artificial con SCMoV-C, se seleccionaron y cultivaron plantas libres de síntomas y se realizaron cruzamientos controlados, entre hermanos, con líneas endogámicas y autofecundaciones. La selección recurrente de plantas asintomáticas y autofértiles aumentaron considerablemente la frecuencia de individuos asintomáticos después de la inoculación con SCMoV-C en el germoplasma en desarrollo.
