Application of Principal Components Analysis for Selection of Parental Materials in Rice Breeding
Year: 2018
Type: article
Abstract: An investigation was carried out to determine agro-morphological variability among 64 accessions and relationships between parental materials suitable for various rice breeding programs in Rwanda.Trials were laid in an 8 x 8 lattice square designs, replicated twice in each of three locations.The analysis of variance revealed significant differences between genotypes for 18 studied agro-morphological traits, with environmental effects being of relatively minor importance.Principal component analysis extracted seven components contributing to around 72% of total variatiability.Three components which were most reliable to variability were highly correlated with a number of traits such as plant height, number of branches per panicle, number of grains per panicle, single panicle weight, grain yield and number of tillers.
