“…The use of recurrent selection is one of the strategies recommended to break such threshold. This breeding method increases the frequency of favorable alleles in a population through selection and cross-linking cycles, explores genetic variability, and results in a greater probability of obtaining genetic gains (ALVES et al, 2015).…”

Predominant trait inheritance in wheat with multivariate approach

The objective of this study was to analize the inheritance of characters in wheat using multivariate analysis of variance. Sixteen genetic constitutions were evaluated between commercial cultivars and progenies F1 and F2. Treatments were arranged in completely randomized blocks, with three replicates. Five characters were evaluated. Multivariate analysis of variance and multivariate contrasts were then performed to test the hypotheses. The significant differences, obtained for comparison between parents and progenies F1, may be evidence of heterosis occurrence. However, only comparisons between progenies P1_P3 (F1) vs. P1_P3 (F2) and P4_P2 (F1) vs. P4_P2 (F2) showed significant differences. Multivariate analysis of variance revealed that inheritance of the characters studied is predominantly of the additive type. It is possible that, this occurred due to the degree of relationship between parents who reunited identical alleles at the same locus, by ancestry, as a result of inbreeding effects. The knowledge of additive inheritance may represent a faster incorporation of resistance or quality characteristics in new cultivars.

“…Common bean breeding programs conducted via recurrent selection usually work with a total of 20 populations, and at the evaluation step, 19 progenies are obtained from each population. Those 380 progenies are evaluated in a 20 x 20 lattice scheme, together with 20 checks (Alves et al, 2015;Batista et al, 2017;Resende et al, 2016). In this sense, 20 breeding population and 19 plants within each population were selected to start a common bean program via recurrent selection.…”

“…In addition, the assessment of quantitative traits requires the evaluation of progenies, which are derived by selecting individual plants within population. Choosing the best breeding populations and plants is a crucial step in a breeding program via recurrent selection since it maximizes the use of human and financial resources (Alves et al 2015;Bernardo, 2012;Mendes et al, 2012;Pires et al 2014;Silva et al 2010).…”

Choosing breeding populations in a common bean (Phaseolus vulgaris L.) breeding program via recurrent selection is a crucial step since it maximizes the effort to find superior inbred lines. The application of the mixed models methodology (REML/BLUP) in predicting breeding values has shown good results in animal and perennial crops breeding programs. Conversely, studies on the application of this methodology to annual crops are still scarce. The present work aimed to use the REML/BLUP methodology to select breeding populations of a common bean breeding program via recurrent selection. Thirty-five F 3 populations were evaluated. Individual plants data were assessed for grain yield and hypocotyl diameter, and the genetic potential of the population was estimated via the mixed models and the Jinks and Pooni's methodologies. A selection index was applied to the selection among and within population, considering both characters simultaneously, using the population and individual BLUP means. REML/BLUP has shown to be a feasible methodology to predict and select the potential of breeding populations, considering more than one character. Selecting individual plants within population provides positive genetic gain estimates for both characters. BLUP breeding values are fundamental to the choice of the number of populations and single plants to be conducted in a common bean breeding program via recurrent selection.
