2013 Pinheiro J, Bates D, DebRoy S, Sarkar D, Team RC. (2013) nlme: Linear and nonlinear mixed effects models. R package version 3(1):111. ) of the R software ( R Core Team 2015 R Core Team (2015) R: A language and environment for statistical computing. R Foundation for Statistical Computing, Vienna. Available at . Accessed on . g/. ). The models included replications within environments (years and/or sowing dates within a year) and environments as fixed factors, and genotypes and the genotype ? environment interaction as random factors. 05. Variance components and narrow-sense heritability were estimated according to Alonso et al. (2018 Alonso MP, Mirabella NE, Panelo JS, Cendoya MG and Pontaroli AC (2018) Selection for high spike fertility index increases genetic progress in grain yield and stability in bread wheat. Euphytica 214: 112. ).

Quantitative trait loci analysis was conducted with Composite Interval Mapping (CIM) using QTL Cartographer software ( Wang et al. 2012a Wang S, Basten CJ and Zeng ZB (2012a) Windows QTL cartographer 2.5. North Carolina State University, Department of Statistics, Raleigh. Available at . Accessed on . ). Best linear unbiased predictors (BLUP) for each RIL, obtained from the mixed model, were used in QTL analysis. Threshold was calculated with 500 permutations and a 0.05 critical level of significance. Up to ten markers showing the highest F value after the forward-backward stepwise regression analysis were added as cofactors in the CIM step [model 6, using a moving window size of 10 centiMorgan (cM) and a walking speed of 1 cM]. The most likely position of the QTL was determined as the point with the maximum logarithm of the odds (LOD) score. The confidence interval (CI) of each QTL was defined as the map interval corresponding to a LOD-2 decrease to each side of the LOD peak. A linear fixed model was fitted to calculate the additive effect (a) of each QTL. The model included QTL and QTL ? QTL interaction effects, and BLUPs were used as phenotypic values. The proportion of the genetic variation explained (R 2 ) by all QTL was obtained from this model. 05.

Haplotype is created for each RIL using the marker associated with the brand new peak of the limitation LOD-get of each and every QTL understood. Haplotype dimensions was basically tested with the Chi-square sample (p worthy of = 0.05, df = 7). Due to heteroscedasticity anywhere between haplotype communities, Welch’s ANOVA sample is actually carried out using userfriendlyscience package ( Verboon mais aussi al. 2018 Verboon P, Chan An effective, Baggett J, McNeish D, Sabbe N, Bonett D, Moinester Meters, Gruijters S, Pat-El Roentgen (2018) userfriendlyscience-package: Userfriendlyscience (UFS). ) of Roentgen app, and you may haplotype distinctions was in fact estimated making use of the Game-Howell nonparametric test.
