The study aimed to test the lines of mutant 6 populations (M6), the formation of populations for a subsequent generation to M8 mutants, family formation through adaptive genotype (mutant) selection at low altitudes at high temperatures in the dry and rainy seasons, adaptation tests, stability, and multi-location. The benefits of the study are obtaining potential lines from wheat mutants that are adaptive at high temperatures in the lowlands. This research was carried out in Jeneponto Regency, South Sulawesi from July to October 2018. The study was in the form of a trial using a randomized block design with three replications. The treatment consisted of twenty wheat genotypes, namely: g1 (M 1.7.1), g2 (N.350 3.6.2), g3 (N.250 4.2.1), g4 (N.350 3.1.3), g5 ( N.350 3. 2.2), g6 (N.250 45.2), g7 (N.350 3.1.4), g8 (N.250 4.6.2), g9 (N.350 3.8.9), g10 (N. 250 4.4.2), g11 (N.350 3.5.10, g13 (N.200 2.4.B.6), g12 (S. 8.4.2), g14 (N.200 2.5.2), g15 (N. 200 2.3.3), and g16 (N.300 4.3.6), and 4 comparison varieties, namely g17 (Dewata), g18 (Selayar), g19 (Nias), and g20 (Munal). Parameters observed for plant height, length of panicle, number of seeds, seed weight per panicle and production The results showed that the M6 wheat mutant lines genotypes adaptive to lowland and had production > 1.6 g.clump-1 namely genotype N.200 2.4.B.6 (2.12 g.clump-1), N.250 4.2.1 (1.87 g.clump-1), N.350 3.1.3 (1.73 g.clump-1) and g7 (N.350 3.1.4) (1.72 g.clump-1). Characters with broad genetic diversity coefficient and high heritability were the number of seeds per panicle, seed weight per panicle, and production.
