Northern Minnesota is conducive for cool-season turfgrass seed production and has existing infrastructure to produce turfgrass seed. There is an exciting opportunity for Northern Minnesotan farmers to

Association between seed production traits in Urochloa spp. Crop Sci. (IF 2.3) Pub Date : 2023-07-22 Gabriela Faria dos Santos, Gustavo Vitti Môro, Jairo Gonçalves Pinheiro, Beatriz Tomé Gouveia, Ulisses José de Figueiredo
Urochloa spp. are excellent perennial forages and are among the best grasses for livestock production. The seed yield is an important trait because it impacts the seed production cost and, consequently, the cost of establishing pastures. The objective of this study was to estimate the genetic correlation between traits related to seed production in Urochloa spp. The experiment was evaluated in 2019

Index-based selection of potato (Solanum tuberosum L.) genotypes for tolerance to soil moisture and ambient heat stress Crop Sci. (IF 2.3) Pub Date : 2023-07-21 Dandena Gelmesa, Nigussie Dechassa, Wassu Mohammed, Edossa Etissa, Endale Gebre, Philippe Monneveux
Developing potato varieties that have enhanced tolerance to soil moisture and high-temperature stress could improve household food and nutrition security in drought and heat prone areas. A field experiment was conducted at two locations in Ethiopia to evaluate the effectiveness of some stress tolerance indices for the identification of drought and heat tolerant potato genotypes. Treatments consisted

Identification of genetic loci for powdery mildew resistance in bread wheat Crop Sci. (IF 2.3) Pub Date : 2023-07-21 Dehui Zhao, Jianqi Zeng, Dan Liu, Yubing Tian, Shawai Rabiu Sani, Xiaowan Xu, Yuanfeng Hao, Zhonghu He, Chunping Wang, Li Yang, Jingdong Liu, Yong Zhang
Powdery mildew is a very destructive disease that threatens yield and quality of wheat. In the present study, 262 recombinant inbred lines derived from a cross between Zhongmai 578 (ZM578) with moderate resistance to powdery mildew and Jimai 22 (JM22) with high resistance to powdery mildew in the field were used to map powdery mildew resistance loci using the high-density Illumina iSelect 50K single-nucleotide

Evolutionary and expression analysis of starch synthase genes from Tartary buckwheat revealed the potential function of FtGBSSII-4 and FtGBSSII-5 in seed amylose biosynthesis Crop Sci. (IF 2.3) Pub Date : 2023-07-17 Lei Wang, Linling Liu, Huala Wu, Chenglei Li, Haixia Zhao, Qi Wu
The starch synthase has been identified well as a core enzyme in the starch biosynthesis pathway in monocots. However, only a few starch synthase genes (SSs) are known in dicots. Tartary buckwheat (Fagopyrum tataricum Gaertn.) is one of the dicots-enriched starch in the seeds, but its starch synthesis pathway remains unclear. Here, 15 SS genes were identified in the Tartary buckwheat genome, including

Genetic characterization of FODMAPs and ATIs in heritage and modern spring wheat Crop Sci. (IF 2.3) Pub Date : 2023-07-17 Prabin Bajgain, Prince G. Boakye, Ibilola Kougblenou, Takehiro Murai, George A. Annor, James A. Anderson
The fermentable oligo-, di-, and monosaccharides and polyols (FODMAPs) and amylase–trypsin inhibitors (ATIs) present in wheat flour can trigger irritable bowel syndrome (IBS) symptoms and intestinal inflammation. Lowering FODMAPs and ATIs concentrations in wheat flour could make the grain accessible to humans with IBS. This study evaluated a diverse panel of heritage and modern spring wheat lines for

Effect of nitrogen application rate and harvesting stage on yield and agronomic parameters of industrial hemp (Cannabis sativa L.) Crop Sci. (IF 2.3) Pub Date : 2023-07-14 Sıdıka Ekren, Gulsum Ozturk, Adem Gokçol, Mustafa Ertekin, Hakan Geren, Emre Ilker
Hemp (Cannabis sativa L.) is one of the world's oldest and most diversely cultivated plants, but legal constraints and a lack of agronomic rules have curtailed its production. This study aimed to determine the optimum nitrogen (N) application rate and harvesting stage for hemp yield in terms of seed, fiber, and stem. Treatments included (1) five nitrogen application rates (control [N0], 60 kg ha−1

Enhancing youth's retention in potato farming enterprise through consortium agribusiness models in Tanzania Crop Sci. (IF 2.3) Pub Date : 2023-07-12 Semeni Ngozi, Shiferaw Feleke
The future of African youth probably lies in agriculture; however, this can be realized by making agriculture both profitable and attractive to young people. The importance of increasing youth involvement in agricultural value chains is primarily to sustain food production and secondly to reduce youth unemployment. Youth can be involved in various segments of agriculture and food value chains including

Application of the scaling readiness approach for scaling of nutrition-sensitive initiatives in Kenya, Uganda, and Malawi: A case of orange fleshed sweetpotato value chain Crop Sci. (IF 2.3) Pub Date : 2023-07-06 Rose Nakhaye Chesoli, Murat Sartas, Tawanda Muzhingi, Owako Emanuel
Malnutrition remains a global challenge contributing to 45% of child mortality worldwide. Agri-nutrition-sensitive interventions have been judged as cost-effective in addressing the key underlying determinants of nutrition. There is conclusive evidence of nutritional benefits from agriculture-related programs such as the orange-fleshed sweetpotato (OFSP) program in addressing vitamin A deficiency which

A practical method to improve the efficiency of pollination in maize breeding and genetics research Crop Sci. (IF 2.3) Pub Date : 2023-07-04 Dylan L. Schoemaker, Frank McFarland, Brian Martinell, Kathryn J. Michel, Lucas Mathews, Dan O'Brien, Natalia de Leon, Heidi F. Kaeppler, Shawn M. Kaeppler
Seed increase through manual pollination is a critical part of maize breeding and genetics research to advance generations in breeding programs, to create desired research crosses, and produce hybrid seed for trials. Pollination in the field and in controlled environments relies on the availability of high-quality pollen at the time that recipient silks are receptive. Generally, pollinations are made

Identification of solvent retention capacity quantitative trait loci by combined linkage and association mapping in wheat (Triticum aestivum L.) Crop Sci. (IF 2.3) Pub Date : 2023-07-03 Jiang Xiao-ling, Li Hong-min, An Yu-ling, Zhao Ji-shun, Geng Yan-yan, Li Xiao-jun, Guan Qing-yun, Yan Mei-ling, Tian Ji-chun, Chen Jian-sheng
Solvent retention capacity (SRC) is an important tool for assessing wheat quality by estimating the biochemical characteristics of flour components. Although it has been widely used in wheat breeding programs, its genetic architecture is still poorly understood. Hence, the objective of this study was to find quantitative trait loci (QTLs) associated with four SRC traits, namely sucrose SRC, sodium

Assessing the fertilizer and pesticide input needs of cool-season turfgrass species Crop Sci. (IF 2.3) Pub Date : 2023-06-28 Ross C. Braun, Eric Watkins, Andrew B. Hollman, Aaron J. Patton
Professional turfgrass managers and consumers continue to express interest in low-input turfgrasses; however, the potential reductions in maintenance inputs from “low-input” turfgrasses are largely assumed and have not been well-quantified. Over 3 years, replicated field experiments at Purdue University and the University of Minnesota quantified the performance and the amount of fertilizer and pesticide
