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.

General characters
Medium cycle variety (130-140 days), it is characterized by tolerance to saline tenors with an electrical conductivity of 4 and 7 d.Sm-1. It surpasses the donor J-104 in a group of characters of economic importance, among which are: tolerance to salinity and P. grisea , number of whole grains and tillering capacity, among others. It also has a shorter cycle.
