Breeding for potato cyst nematode resistance in Solanum tuberosum Crop Sci. (IF 2.3) Pub Date : 2024-04-11 Pia Spychalla, Walter S. De Jong
Two species of potato cyst nematodes (PCNs), Globodera rostochiensis (Woll.) and Globodera pallida (Stone), threaten potato (Solanum tuberosum L.) production worldwide. PCNs are remarkably persistent in soil and can reduce potato yield significantly. The most sustainable approach to PCN control is deploying resistant cultivars. This review focuses on the knowledge needed to conduct a successful PCN

Evaluating cultivar intensity and dataset size for reliable cultivar recommendation in winter wheat: A systematic research of environmental and genotype factors Crop Sci. (IF 2.3) Pub Date : 2024-04-11 Marzena Iwańska, Jakub Paderewski, Jan Žukovskis, Elżbieta Wójcik-Gront
Crop yield is influenced by environmental, genotype, and management factors. This study focuses on the environmental and genotype factors, specifically the concept of mega-environments, where similar crop varieties thrive due to similar environmental conditions, and cultivar intensity, a cultivar's favorable reaction to improved growing conditions, in cultivar recommendation for winter wheat in Poland

Evaluation of variation in seedling root architectural traits and their potential association with nitrogen fixation and agronomic traits in field pea accessions Crop Sci. (IF 2.3) Pub Date : 2024-04-10 Loveleen Kaur Dhillon, Rahul Chandnani, Alireza Nakhforoosh, Tongfei Qin, Karim Panjvani, J. Allan Feurtado, Leon Kochian, Thomas D. Warkentin
Root system architecture (RSA) plays a central role in water and nutrient acquisition in plants. Plasticity and genetic variation in RSA can be used as an adaptive strategy to optimize plant performance under variable environments. We quantified phenotypic variation for seedling RSA among 44 diverse pea (Pisum sativum L.) genotypes, including breeding lines and germplasm accessions, grown under controlled

Genetic variation for endosperm carbohydrates and total soluble solids in shrunken2, sugary1, waxy1, and wild-type near-isogenic corn lines across three harvest dates Crop Sci. (IF 2.3) Pub Date : 2024-04-10 Alexa R. Wilson, Isabella G. Fiore, Cathleen McCluskey, William F. Tracy
Sweet corn (Zea mays L.) cultivars must meet stringent quality standards to be accepted in the marketplace. Breeding for eating-quality traits, such as sweetness, typically involves taste ratings or quantification of carbohydrate content. Total soluble solids (TSS) content is used as a proxy for sweetness in many fruit crops. Using a diallel of near-isogenic corn lines for sugary1, shrunken2, waxy1

An assessment of the linkages between GM crop biotechnology and climate change mitigation GM Crops Food (IF 3.9) Pub Date : 2024-04-08 Stuart J. Smyth, Peter W. B. Phillips, David Castle
This article provides an analysis and evaluation of peer-reviewed evidence on the contribution of crop biotechnology to climate change mitigation and adaption. While there is a range of agricultura...

Constructing eRNA-mediated gene regulatory networks to explore the genetic basis of muscle and fat-relevant traits in pigs Genet. Sel. Evol. (IF 4.1) Pub Date : 2024-04-09 Chao Wang, Choulin Chen, Bowen Lei, Shenghua Qin, Yuanyuan Zhang, Kui Li, Song Zhang, Yuwen Liu
Enhancer RNAs (eRNAs) play a crucial role in transcriptional regulation. While significant progress has been made in understanding epigenetic regulation mediated by eRNAs, research on the construction of eRNA-mediated gene regulatory networks (eGRN) and the identification of critical network components that influence complex traits is lacking. Here, employing the pig as a model, we conducted a comprehensive

Large-scale breeding population validating significant loci for the 1000-kernel weight of wheat Crop Sci. (IF 2.3) Pub Date : 2024-04-09 Peng Jiang, Chang Li, Fa Cui, Lei Wu, Zhaoyang Zhang, Yi He, Peng Zhang, Hongxiang Ma, Xu Zhang
As an important component of wheat (Triticum aestivum L.) yield, 1000-kernel weight (TKW) has played a crucial role in yield improvement in recent decades. Marker-assisted selection is an effective tool for improving quantitative traits; however, most markers have not been effectively applied in TKW improvement despite the identification of many loci associated with TKW. In this study, association
