Response of M5 wheat (Triticum aestivum L.) mutant to low altitude growing condition

Abstract

Abstract This study aims to study the adaptability of wheat mutant lines in the lowlands and determine the growth and production of the mutant lines. The research was conducted from September to December 2017 at Teaching Farm, Faculty of Agriculture, Hasanuddin University, Makassar, South Sulawesi Province. The study was carried out in the form of experiments arranged based on Randomized Block Design and further tested using orthogonal contrast. The treatments given were five M5 mutant genotypes and two convergent breeding genotypes. Three wheat varieties Dewata, Munal, and Selayar were used as comparisons. The results showed that the convergent breeding line (CB 145) showed good genetic traits on plant height parameters and the number of empty floret. Dewata, Munal, and Selayar varieties showed more average number of tillers (6.00 tillers) and 100 heavier grain weight (4.07 g) compared to the mutant genotypes. Dewata variety showed good genetic characteristics on panicle length parameter (6.50 cm) and grain weight per panicle (0.34 g). CB 169 genotype showed good genetic characteristics on the parameter number of grain per panicle which only produced the number of seeds per panicle (8.33 seeds).
