Abstract:
We assembled an international barley panel comprising 282 entries from 26 countries with various levels of field resistance to leaf rust caused by Puccinia hordei. The panel was screened for leaf rust response with an array of pathotypes at the seedling stage, and at the adult plant stage in multiple environments (2013?2015) in Australia and Uruguay, and genotyped using > 13 K polymorphic DArT-Seq markers. Multipathotype testing in the greenhouse postulated the presence of seedling resistance genes Rph1, Rph2, Rph3, Rph4, Rph7, Rph9.am, Rph12, Rph14, Rph15, Rph19, and Rph25. Genome-wide association studies (GWAS) based on field data identified 13 QTLs significantly associated with DArT-Seq markers on chromosomes 2H (Rph_G_Q1, Rph_G_Q2, Rph_G_Q3, and Rph_G_Q4), 4H (Rph_G_Q5), 5H (Rph_G_Q6, Rph_G_Q7, Rph_G_Q8), 6H (Rph_G_Q9 and Rph_G_Q10), and 7H (Rph_G_Q11, Rph_G_Q12, and Rph_G_Q13). Three QTLs (Rph_G_Q3, Rph_G_Q5, and Rph_G_Q6) were detected under all environments, whereas the other ten were variable, being detected in 1?4 environments; Rph_G_Q1 and Rph_G_Q13 being detected only in Uruguay. Among the three QTLs detected under all environments, Rph_G_Q6 on chromosome 5H had the largest effect and corresponded to a region where the cataloged APR gene Rph20 is located. Rph_G_Q3 and Rph_G_Q5 detected on chromosome 2H and 4H aligned with QTLs reported in at least three previous studies. The studies provide useful information towards better understanding of the genetic architecture of seedling and adult plant resistance to leaf rust in diverse global barley germplasm. MenosAbstract:

Summary: Individual and maternal additive and non-additive effects for weights taken every 3 months from birth to 36 months were estimated for Hereford (H/H), Angus (A/A), Salers (S/S) and Nellore (N/N). For the analysis 45.794 weight records from 4.050 animals (2.036 male and 2.014 females), were used. Data corresponds to 39 different breed combinations, H/H and A/A pure breed and 37 groups whit A/A, S/S and N/N crosses with H/H. Data was grouped into 754 contemporary groups defined by sex, year at birth, calving period, experiment, cow parity and the date of weight. Parameters were estimated through model were genetic crossbreeding effects based on Dickerson full model. British breeds provided improved combinations of additive effects, while Zebu breed provided larger values for heterosis and recombination loss. The benefit of using crossbred females is maintained until 3 years of age for British x British and British x Continental. The benefit is also maintained until 3 years of age for Zebu x British while proportion of British is larger than proportion of Zebu. Additive and non-additive effects relevance are maintained at least until 36 months of age. The best combination for growth until 36 months of age is obtained by F1 N/H females, given the maximum use of maternal heterosis and the use of half of the individual heterosis between these breeds, which compensates the negative additive effects of the Zebu breed. |
