| Abstract | Seeds of M5 generation of two salt tolerant and photoperiod insensitive KDML105 mutant lines were grown and 6 hills of each line were selected. The 12 lines of M6 generation were compared to the control KDML105 using randomized complete block design (RCBD) with 3 replicates. They were further self-pollinated to produce M7 generation. The tillers/hill, panicles/hill, seeds/panicle, and yield/rai of these 12 M6 lines were not statistically different from the KDML105 control. Four lines (K1, K3, K7, K9) from the 12 M6 lines with strong tendency to have increased yield/rai were selected, The DNA was extracted for AFLP analysis using 15 pairs of primers. The results showed a total of 239 bands, 211 (88.33%) of which are monomorphic and 28 (11.70%) are polymorphic. These four mutant lines were 86.66-88.33% similar in genetic composition compared to the KDML105 control |
