The goal of this study was to verify the effect of heterogeneity of variance (HV) on milk production in up to 305 days of lactation (L305) of daughters of Girolando, Gir and Holstein sires, as well as in the genetic evaluation of these sires and their progenies. in Brazil. The model included contemporary groups (consisting of herd, year and calving season) as a fixed effect, cow age at calving (linear and quadratic effects) and heterozygosity (linear effect) as covariates, in addition to the random effects of direct additive genetic and environmental, permanent and residual. The first analysis consisted of the single-trait animal model, with L305 records (disregarding HV). The second considered classes of standard deviations (SD): two-trait model including low and high classes (considering HV), according to the standardized means of L305 for herd-year of calving. The low SD class was composed of herds with SD equal to or less than zero and the high class with positive SD values. Estimates of (co)variance components and breeding values were obtained separately for each scenario using Bayesian inference via Gibbs sampling. Different heritability was estimated. Higher for the high DP class in the Gir (0.20) and Holstein (0.15) breeds, not occurring the same in the Girolando breed, with a lower value among the classes for the high DP (0.10). High values of genetic correlations were also found between low and high SD classes (0.88; 0.85 and 0.79) for the Girolando, Gir and Holstein breeds, respectively. Like the order correlations (Spearman) which were also high for the three breeds analyzed (equal to or above 0.92). Thus, the presence of HV had a smaller impact for L305 and did not affect the genetic evaluation of sires.

ABSTRACT - The objective of this work was to evaluate the viability of the micrografting of yellow dragon fruit (Selenicereus megalanthus) on different rootstocks, based on DNA content and anatomical analyses. The used rootstocks were: yellow dragon fruit, white dragon fruit (Hylocereus undatus), Saborosa (Selenicereus setaceus) dragon fruit, and the Cebra and Orejona red dragon fruit (Hylocereus polyrhizus) varieties. The experimental design was completely randomized with five treatments and four replicates of five plants. After 30 days of cultivation, the following traits were evaluated: length and diameter of the micrografts and microrootstocks; and root length, percentage of setting, and fresh mass of the micrografts. Flow cytometry analyzes were performed before and after micrografting to verify genetic stability and the occurrence of endoreduplication. In addition, histological sections were made in the micrografting region to verify the connections of vessels and tissues between the graft and the rootstock. Endoreduplication was observed in all treatments. The amount of DNA in the yellow dragon fruit micrograft increased on the red Orejona variety. The presence of vessel connections was verified between the micrografts and microrootstocks. The yellow dragon fruit was also more vigorous when grafted on Orejona. Based on DNA content and anatomical analyses, in vitro yellow dragon fruit micrografting is feasible in all used rootstocks. RESUMO - O objetivo deste trabalho foi avaliar a viabilidade da microenxertia de pitaia amarela (Selenicereus megalanthus) sobre diferentes microportaenxertos, com base em análises de conteúdo de DNA e anatômicas. Os portaenxertos utilizados foram: pitaia amarela, pitaia branca (Hylocereus undatus), pitaia Saborosa (Selenicereus setaceus), e as variedades Cebra e Orejona de pitaia vermelha (Hylocereus polyrhizus). O delineamento experimental foi inteiramente casualizado, com cinco tratamentos e quatro repetições de cinco plantas. Após 30 dias de cultivo, avaliaram-se as seguintes características: comprimento e diâmetro dos microenxertos e dos microporta-enxertos; e comprimento de raízes, percentagem de pegamento e massa fresca dos microenxertos. Realizaram-se análises de citometria de fluxo antes e depois da microenxertia, para verificação da estabilidade genética e da ocorrência de endoreduplicação. Além disso, foram feitos cortes histológicos na região da microenxertia, para verificação das conexões dos vasos e dos tecidos entre o enxerto e o porta-enxerto. Observou-se endoreduplicação em todos os tratamentos. A quantidade de DNA do microenxerto de pitaia amarela aumentou sobre a variedade vermelha Orejona. Verificou-se a presença de conexões de vasos entre os microenxertos e os microportaenxertos. A pitaia amarela também foi mais vigorosa quando enxertada sobre Orejona. Com base nas análises de conteúdo de DNA e anatômicas, a microenxertia de pitaia amarela in vitro é viável em todos os porta-enxertos utilizados.
