The effects of the transferred green rice leafhopper (GRH) resistant gene on yield and grain quality were analyzed by using 7 near-isogenic lines (NILs) with introgressed GRH resistance gene in rice cultivar "Ilpumbyeo". The genotype analysis using SSR markers indicated that all NILs were recovered more than 95% as compared with recurrent parent "Ilpumbyeo". All NILs showed no significant differences compared to recurrent parent for grain yield. No significant differences were observed between NILs and their recurrent parent for physicochemical traits (protein content, amylose content and alkali spreading value) and eating quality. But there were significant differences for appearance of brown and milled rice and pasting properties between some NILs and their recurrent parent. It means that these grain appearance and pasting traits of NILs were very similar or more improved compared to recurrent parent "Ilpumbyeo". Thus, it could be possible to develop GRH resistant variety with high ,quality in segregating populations.
