| Abstract (English): |
The determination of four Cuban varieties of garlic was made so as to optimize the use of ionizing radiations in Cuba to breed vegetatively propagated crops such as garlic. The dose-effect regresion equation characterizing the radioinhibition zone of each crop was presented. We used a criteria to select the irradiation dose to be used in mutation breeding techniques based on obtaining height variability in the productive indicators, a survival and a number of garlic cloves high enough to allow an adequate reproduction of M1 plants. It was verified that this small inhibitor doses of radiations produced a higher percentage of good variability than the medium and high doses. With the use of small inhibitor doses (GR10-GR20) on the Guadalupe-15 garlic variety, 65 variety plants were obtained., 93.7% out of this number is higher than the control in the indicators considered.

| Abstract (Spanish): |
Se determinó la radiosensibilidad de cuatro clones cultivados en el país con el propósito de optimizar el uso de las radiaciones ionizantes en Cuba para mejorar plantas de reproducción asexual, tales como el ajo. Se presenta la ecuación de regresión dosis-efecto que caracteriza la zona de radioinhibición de cada cultivar. Para obtener una mayor variabilidad positiva en los índices productivos, una supervivencia y un número de dientes sanos por bulbo, suficientemente altos que permitan una adecuada reproducción de las plantas M1, y de acuerdo con los resultados obtenidos, se recomienda utilizar la dosis que reduce la altura de las plantas en un 10-20% con respecto al testigo (GR10-GR20) como la más eficaz para el mejoramiento del ajo por radiomutagénesis, ya que se comprobó que esta dosis de radiaciones inhibidora es capaz de producir un porcentaje de variabilidad provechosa superior a la que inducen dosis inhibidoras medias o severas. Con su empleo en el ajo cv Guadalupe-15, se obtuvieron 65 individuos variados, de ellos el 93,7%, supera al testigo en los índices considerados. [ABSTRACT FROM AUTHOR] |
