| In order to screen barley genotypes with the extreme grain protein or nitrogen nutrition content,a total of 90 genotypes of Hordeum Spontaneum collected from nine different habitats in Israel were planted in four environments,e.g. Y2012 Farm,Y2013 AS,Y2013 Garden and Y2013 9F in Guizhou province in 2012 and 2013. The grain soluble protein(GSP) and grain total nitrogen content(GTN) of the 90 H.Spontaneum genotypes were measured in different environments for screening nitrogen nutrition-related genotypes. The results showed that the mean value of GTN in Y2012 Farm was significantly higher than that in Y2013 AS. While the mean value of GSP in Y2013 AS was significantly higher than that in other three environments. In both 2012 Farm and Y2013 AS environments,the Tabigha population had the highest GTN,whereas the Golan High and Hermon populations had the lowest,respectively,which both had significance compared with the Tabigha population. Among the three environments,Y2012 Farm,Y2013 AS and Y2013 Garden,the GSP of the Gilboa population was significantly higher than that of the other populations. It means that the accumulation of grain nitrogen nutrition was affected by environmental conditions,and with some conservatism. In both Y2012 Farm and Y2013 AS environments,T8,R23 and R3 genotypes had the higher GTN,with the mean value of 3.42%,3.04% and 3.12%,respectively,while GN26 had the lower GTN,with the average value of 2.01%. Through the comprehensive comparison,it was found that the genotypes T8 and HM17 had the extremely high and low nitrogenous nutrition,respectively,among all the tested genotypes of wild barley,which could be used for the improvement of modern cultivated barley. |
