GINES LP-18

GINES LP-18: Variety of Cuban rice, excellent grain and medium cycle. It was obtained at the Experimental Rice Station located in Los Palacios , belonging to the National Institute of Agricultural Sciences , from the in vitro cultivation of seeds of the rice cultivar J-104 , irradiated with protons in the DUVNA Fasotron. They were then subjected to saline concentrations with an electrical conductivity of 4 and 7 d.Sm-1, respectively, with which plants tolerant to these saline tenors were selected, thus becoming one of their main agronomic characteristics.
