| dc.description.abstract | One of approaches to maintain the yield stability of the lowland tropical wheat is the use of secondary traits in the
selection process. The identification of these characters requires a statistical approach in the form of genetic parameter analysis and
multivariate analysis. The objective of this study was to determine the secondary traits of adaptive wheat mutants in the lowlands
through the use of genetic parameters and multivariate analysis on the parameters. The study consisted of three field trials conducted in
three different regencies, namely Jeneponto (135 m above sea level (asl)), Maros (100 m asl) and Bantaeng (125 m asl). The study used
a nested design, where replications were nested in the environments. The genotype factors consisted of 20 genotypes repeated three
times. 11 characters were observed including vegetative and reproductive characters. The analysis used consisted of repeatability,
correlation, cluster analysis, principal component analysis, factor analysis, and cross print analysis. The overall results of the analysis
indicate that the number of productive tillers is the main secondary trait for the selection of adaptive wheat in the lowlands. The
character can be recommended for selection criteria in testing wheat lines in the lowlands to make an effective selection | en_US |
