Means followed by same letters are statistically not different (), by Tukey’s honest significance test. DFF: days to 50% flowering; PH: plant height in cm; ETP: effective tillers per plant; PL: panicle length in cm; TW: weight of 1000 grains in grams; YLD: yield in g per hill; STS: salt tolerance score (IRRI, 2013); RP: number of recurrent parent homozygotes; DP: number of donor parent homozygotes; HT: heterozygotes; RPG: recurrent parent genome recovery; CV: coefficient of variation; SE: standard error.
