Winter wheat response to plant density in yield contest fields Crop Sci. (IF 2.0) Pub Date : 2024-07-17 Romulo P. Lollato, Luiz O. Pradella, Nicolas Giordano, Luke P. Ryan, Jorge R. Soler, Luana M. Simão, Brent R. Jaenisch, Rick Horton
Seeding rate recommendations for wheat (Triticum aestivum L.) are often 150–450 seeds m−2. However, we hypothesize that wheat grown with high resource availability (i.e., fertility and moisture) can maximize yield under considerably lower rates. Our objectives were to explore winter wheat response to low populations under high resource availability using yield‐contest fields as a case study. A factorial

Overexpression of the late embryonic genesis abundant protein MGL3 improves the drought tolerance of maize (Zea mays L.) Crop Sci. (IF 2.0) Pub Date : 2024-04-21 Jiaqi Liu, Nannan Chen, Bai Gao, Ming Miao, Yang Zhao, Siyan Liu, Shuyan Guan, Yiyong Ma
With the increasing severity of climate change, drought has become a global issue that seriously restricts the development and production of crops. Maize (Zea mays L.) is one of the major food crops in the world. Therefore, the demand for drought-tolerant maize varieties has been rapidly increasing in the market. Recent studies have found that late embryogenesis abundant (LEA) proteins are involved

Phenotypic diversity for morpho‐agronomic traits in the US proso millet (Panicum miliaceum L.) core collection Crop Sci. (IF 2.0) Pub Date : 2024-04-17 Santosh G. Rajput, Rituraj Khound, Dipak K. Santra
Proso millet (Panicum miliaceum L.) is a short‐season annual crop known for high water‐use efficiency and drought tolerance. The low water requirement makes this ancient grain an excellent rotational crop for the winter wheat‐based dryland cropping system in the High Plains of the United States. The genetic base of the commonly grown US cultivars is very narrow. Assessment of proso millet germplasm

Analysis of factors influencing market participation among orange-fleshed sweet potato smallholder farmers in southern region of Malawi: A case of RTC project Crop Sci. (IF 2.0) Pub Date : 2024-04-12 McDonald Chikhawo, Samson Katengeza, Julius J. Okello, M. Alexander. R. Phiri, Felistus Chipungu
Agricultural markets remain major issue downgrading root and tuber crop farmers who form the mainstream of the agricultural producers in Malawi. Recent evidence however reveals that orange-fleshed sweet potato (OFSP) (Ipomea batatas) is currently being sold in produce markets along with the non-orange varieties, sometimes in differentiated form in Malawi. The main objective of this study was to examine

Breeding for potato cyst nematode resistance in Solanum tuberosum Crop Sci. (IF 2.0) 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 2.0) 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 2.0) 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 2.0) 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

Large-scale breeding population validating significant loci for the 1000-kernel weight of wheat Crop Sci. (IF 2.0) 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

Changes in the content of carotenoids in potato tubers cultivated with or without the application of fungicides Crop Sci. (IF 2.0) Pub Date : 2024-04-08 Beata Tatarowska, Dorota Milczarek, Jarosław Plich
In this study, three cultivars and seven tetraploid potato clones were evaluated for two years in two cultivation systems (CS): without chemical protection against late blight development (NP) and with chemical protection (P). The objective of this study was to quantify the effect of chemical protection on the level of total carotenoids (TC) and individual carotenoids in potato tubers. The presented
