“…The typical statistical methodology used for yield analysis in common vetch breeding programs is still mostly based in early methods such as analysis of variance or simple variance components mixed models ( Berger et al., 2002 ; Georgieva et al., 2015 ; Aydemir et al., 2019 ; Dong et al., 2019 ). These models assume variance structures which may not be realistic and do not allow to explore patterns in the G x E interaction ( Kempton, 1984 ; Smith et al., 2005 ).…”

Common vetch is one of the most profitable forage legumes due to its versatility in end-use which includes grain, hay, green manure, and silage. Furthermore, common vetch is one of the best crops to rotate with cereals as it can increase soil fertility which results in higher yield in cereal crops. The National Vetch Breeding Program located in South Australia is focused on developing new vetch varieties with higher grain and dry matter yields, better resistance to major diseases, and wider adaptability to Australian cropping environments. As part of this program, a study was conducted with 35 field trials from 2015 to 2021 in South Australia, Western Australia, Victoria, and New South Wales with the objective of determining the best parents for future crosses and the vetch lines with highest commercial value in terms of grain yield production. A total of 392 varieties were evaluated. The individual field trials were combined in a multi-environment trial data, where each trial is identified as an environment. Multiplicative mixed models were used to analyze the data and a factor analytic approach to model the genetic by environment interaction effects. The pedigree of the lines was then assembled and incorporated into the analysis. This approach allowed to partition the total effects into additive and non-additive components. The total and additive genetic effects were inspected across and within environments for broad and specific selections of the lines with the best commercial value and the best parents. Summary measures of overall performance and stability were used to aid with selection of parents. To the best of our knowledge, this is the first study which used the pedigree information to breed common vetch. In this paper, the application of this statistical methodology has been successfully implemented with the inclusion of the pedigree improving the fit of the models to the data with most of the total genetic variation explained by the additive heritable component. The results of this study have shown the importance of including the pedigree information for common vetch breeding programs and have improved the ability of breeders to select superior commercial lines and parents.

Wild-growing varieties are used in the breeding of Vicia sativa L. in order to expand genotypic diversity and improve the environmental stability of created varieties. In order to find wild-growing vetch possessing valuable breeding traits, 22 specimens from 15 countries were evaluated. Tests were conducted in a field experiment in the south of Moscow Oblast in 2018, 2020, and 2021. The ‘Vera’ variety served as the reference. On the basis of three-year data and in accordance with the International Classification of Vicia sativa L., the specimens were evaluated for early maturity, crop and seed production, seed size, leading shoot length, branchiness, number of pods per plant, and number of seeds in a pod. All the specimens were characterized by early maturity of fodder mass and seeds. The three-year average duration of the “sprouting- crop ripeness” period amounted to 34.7-46.3 days, while that of “sprouting-seed maturity” reached 59.0-67.5 days. In wild-growing specimens, the dry weight of the plant in the phase of crop ripeness ranged from 1.0 to 5.0 g (18-92 % of the reference). The fodder mass yield per plant was lower than that of the reference variety due to the poorer development of lateral shoots. Nineteen specimens were at the same level as or superior to the reference variety in terms of plant height. The three-year average seed yield of the specimens varied from 1.3 to 3.2 g (28-70 % of the reference). An analysis of seed yield showed that all specimens produced fewer pods than the reference. However, seven specimens were identified to be annually superior to the reference in terms of other traits: seed size (kk-36830, 36831, 36837, 36848, and 36850); the average number of seeds in the pod (kk-36871); the maximum number of pods in a node; the number of pods and the number of productive nodes on the leading shoot (kk-36879). These specimens are of interest for use in breeding vetch for seed yield.
