Genotype by environment interaction (GEI) is one of the key factors affecting breeding value estimation accuracy for agronomic traits in plant breeding. Measures of GEI include fitting prediction models with various kernels to capture the variance due to GEI, and/or characterizing trials into mega‐environment clusters within which breeding values can be estimated to remove the main GEI effects.

Genetic diversity is enhanced in Wild × Cultivated hybrids of sugarbeet ( Beta vulgaris L.) despite multiple selection cycles for cultivated traits Genet. Resour. Crop Evol. (IF 1.071) Pub Date : 2021-03-04 Karen K. Fugate; Larry G. Campbell; Giovanny Covarrubias-Pazaran; Lorraine Rodriguez-Bonilla; Juan Zalapa
Genetic diversity is enhanced by introgressing wild germplasm into breeding lines and populations. Such introgression, however, commonly introduces wild traits that must be removed by backcrossing and selection before lines are useful for elite breeding programs. Selection against wild characteristics is expected to reduce genetic diversity in introgressed lines. However, the effect of such selection

In order to understand the lignification process, enzymatic and biochemical studies were conducted at four different growth stages of tall fescue (Festuca arundinacea Schreb.). An increase in phenylalanine ammonia lyase and tyrosine ammonia lyase activity was observed with advancement of growth

Estimating the copy number of the agouti signaling protein (ASIP) gene in goat breeds with different color patterns Livest. Sci. (IF 1.7) Pub Date : 2021-02-08 Dailu Guan; Anna Castelló; María Gracia Luigi-Sierra; Vincenzo Landi; Juan Vicente Delgado; Amparo Martínez; Marcel Amills
The agouti signaling protein (ASIP) gene has a crucial role in pigmentation by encoding a protein that binds the melanocortin 1 receptor and stimulates the synthesis of pheomelanin rather than eumelanin. Several studies have suggested that an increased copy number of the ASIP gene might explain the white pigmentation of certain goat breeds, as previously demonstrated in sheep. In the current work,

Effect of walking exercise and nutritional plan on goat performance Livest. Sci. (IF 1.7) Pub Date : 2021-02-15 Marcella Cândia D'Oliveira; Marcelo Vedovatto; Ibrahim Miranda Cortada Neto; Rafaela Nunes Coelho; Maria da Graça Morais; Marina de Nadai Bonin Gomes; João Alberto Negrão; Gumercindo Loriano Franco
This study evaluated the effects of walking exercise and nutritional plan on metabolic variables and the growth of stabled goats. Thirty-six goats [body weight (BW) = 21 ± 0.3 kg] were allocated in individual pens, and the treatments were randomly assigned to the animals in a 2 × 2 factorial design. The treatments consisted of walking exercise (7,5 km/day) or not and two nutritional plans [90 % (0

Difructose anhydride III improves feed intake immediately after calving in multiparous cows Livest. Sci. (IF 1.7) Pub Date : 2021-02-18 Masaaki Hanada; Syaw Wynn; Maimaiti Reshalaitihan
This study was conducted to investigate the effect of difructose anhydride (DFA) III on dry matter intake in multiparous cows immediately after calving. Seventy-four transition multiparous Holstein cows were allocated into control (CONT) and DFA groups. The average parity number in the CONT and DFA groups was 3.70 ± 0.25 and 3.67 ± 0.26, respectively. Individual cow measurements were collected from

Is the farming method (cage, barn, organic) a relevant factor for marketed egg quality traits? Livest. Sci. (IF 1.7) Pub Date : 2021-02-15 Antonella Dalle Zotte; Marco Cullere; Erika Pellattiero; Alberto Sartori; Alberto Marangon; Valerio Bondesan
The present study evaluated the physicochemical and sensory traits of marketed table eggs, deriving from different farming methods (cage, barn, and organic) and sampled in different marketing periods (June, July, September, October). A total of n=540 eggs (n=45 eggs/farming method/sampling period) of “medium” weight-grading were purchased and subjected to physical measurements (shell, yolk, and albumen

Profiles of dairy cows with different productive lifespan emerge from multiple traits assessed at first lactation: the case of a grassland-based dairy system Livest. Sci. (IF 1.7) Pub Date : 2021-02-10 L.B. Mendes; M. Coppa; J. Rouel; B. Martin; B. Dumont; A. Ferlay; C. Espinasse; F. Blanc
This study focuses on extensive grassland-based dairy systems, where cows may be exposed to various hazards (climatic, health…) and limiting environments (feeding conditions) over their life. In such livestock systems, the ability of cows to remain in the herd (i.e. lifespan) reveals their ability to cope with such perturbations and to continue meeting the farmer's expectations. Productive lifespan

Co‐expression gene network (WGCNA) analysis of cold‐tolerant Solanum commersonii reveals new insights in response to low temperatures Crop Sci. (IF 1.878) Pub Date : 2021-02-22 Salvatore Esposito; Riccardo Aversano; James Bradeen; Vincenzo D'Amelia; Clizia Villano; Domenico Carputo
Among abiotic stressors, cold is one of the most harmful for the cultivated potato, a frost‐sensitive crop. RNAseq profiling of two different clones of S. commersonii contrasting in their capacity to withstand low temperatures revealed a higher number of differentially expressed genes (DEGs) under non‐acclimated (NAC) conditions in tolerant clone cmm1T compared to the susceptible cmm6‐6 (1,002 and

Optical sorter‐augmented genomic selection lowers DON accumulation in wheat Crop Sci. (IF 1.878) Pub Date : 2021-02-22 W. Jesse Carmack; Anthony J. Clark; H. Jeanette Lyerly; Yanhong Dong; Gina Brown‐Guedira; David Anthony Van Sanford
Previous results from our lab have shown that optical sorter‐based indirect selection reduced deoxynivalenol (DON) accumulation in soft red winter wheat (SRWW). In this paper we evaluate the efficacy of optical sorter‐augmented genomic selection (OSA‐GS) for lower DON accumulation at three selection intensities across two years. In total, 758 SRWW breeding lines were genotyped and then phenotyped in

Building a reference transcriptome for the hexaploid hard fescue turfgrass (Festuca brevipila) using a combination of pacbio iso‐seq and illumina sequencing Crop Sci. (IF 1.878) Pub Date : 2021-02-22 Yinjie Qiu; Ya Yang; Cory D. Hirsch; Eric Watkins
Hard fescue (Festuca brevipila Tracey, 2n = 6x = 42) is a cool season turfgrass with a fine leaf texture that performs well under low‐input management. Breeding and genetics studies of F. brevipila have been limited due to the complexity of its hexaploid genome. To advance our knowledge of F. brevipila genomics, we used PacBio isoform sequencing to develop a reference transcriptome for this species

An integrative analysis of yield stability for a GWAS in a small soybean breeding population Crop Sci. (IF 1.878) Pub Date : 2021-02-21 Gastón Quero; Sebastián Simondi; Sergio Ceretta; Álvaro Otero; Silvia Garaycochea; Schubert Fernández; Omar Borsani; Victoria Bonnecarrère
Drought stress is one of the most important factors limiting soybean (Glycine max [L.] Merr.) productivity and reducing yield stability. Soybean breeders need phenotypic and genotypic tools to improve the drought stress tolerance but most of available strategies are expensive and unaffordable for small‐scale public breeding programs. In this context, elite germplasm of a locally adapted breeding population

Improving the identification of haploid maize seeds using convolutional neural networks Crop Sci. (IF 1.878) Pub Date : 2021-02-21 Felipe Sabadin; Giovanni Galli; Ronaldo Borsato; Raysa Gevartosky; Gabriela Romêro Campos; Roberto Fritsche‐Neto
A critical step towards the success of the doubled haploid (DH) technique is the haploid identification within induction crosses. The R1‐nj marker is the principal mechanism employed in this task enabling the selection of haploids at the seed stage. Even though it seems easy to identify haploid seeds, this task is performed manually by visual classification, which becomes an inefficient process in
