Sementes do cultivar de arroz de sequeiro IAC-1246 foram tratadas com dosagens de 10, 15 e 20 e 30 Krad de raios-gama e concentrações de 0,5, 1,0 e 5,0 mM de azida sódica (SA). O primeiro objetivo foi analisar o efeito e eficiência mutagênica de cada mutagênico e em combinação, através de mutações de clorofila. Um segundo objetivo foi avaliar o efeito dos tratamentos sobre a média e a variância de plantas M2 dos seguintes caracteres: número de dias até o inicio de floração (DIF), comprimento do colmo (CC) e número de perfilhes (NP). Concentrações maiores ou iguais a 1,0 mM de azida sódica ocasionaram maiores danos que os de raios-gama. Os tratamentos combinados incrementaram os danos, principalmente sobre a altura de plântula e fertilidade ...
