Sunflower (Helianthus annuus L.) is widely utilized for seed oil production. Priming seeds prior to sowing is a technique used to enhance the germination rate and uniformity of seedling growth. Priming times of 6 and 18 h were selected to be the optimal and extended durations, respectively. Three biological replicates per treatment were used for next-generation sequencing via the Illumina platform

Steps toward developing legume cover crop varieties: Study of biomass and nitrogen partitioning and within-plant δ115N variation of faba bean at different growth stages Crop Sci. (IF 2.3) Pub Date : 2024-03-14 Chloe Dugger, Kyle G. Brasier, Mohammad H. Pahlavani, Hossein Zakeri
Modern legumes are engineered to enhance nutrient allocation to grains and maximize harvest index (HI) and yield. Breeding legumes for cover crop requires optimizing source-sink relationship to prolong nutrient allocation to vegetative organs, support post-flowering nodule activity, and extend biological nitrogen fixation (BNF). We studied the variation of faba bean (Vicia faba) germplasm for biomass

Classification of new germplasm into existing heterotic groups of pearl millet [Pennisetum glaucum (L.) R. Br.] Crop Sci. (IF 2.3) Pub Date : 2024-03-13 Rakshith Papanna, I. Shanker Goud, Anilkumar Vemula, B. V. Tembhurene, M. K. Meena, Shashi Kumar Gupta
The study assigned new germplasm, which includes populations and inbreds, to established heterotic groups using various approaches to broaden the existing genetic base while maintaining the heterotic pattern in pearl millet [Pennisetum glaucum (L.) R. Br.]. It utilized 13 pearl millet populations of African and Asian origins and 24 new inbred parents from ICRISAT's breeding program. Testers, both inbred

Identification of QTLs and validation of molecular markers associated with reaction to Fusarium wilt in the common bean cultivar BRS FP403 Crop Sci. (IF 2.3) Pub Date : 2024-03-11 Mário Henrique Rodrigues Mendes Torres, Rosana Pereira Vianello, Thiago Lívio Pessoa Oliveira de Souza, Leonardo Cunha Melo, Saulo Muniz Martins, Lucas Matias Gomes-Messias, Helton Santos Pereira
Fusarium wilt, caused by the fungus Fusarium oxysporum f. sp. phaseoli, is one of the most prevalent diseases in the common bean crop (Phaseolus vulgaris). However, there is little information regarding the genetics of reaction to this disease. Thus, the aims of this study were to estimate genetic parameters, identify quantitative trait loci (QTLs) associated with reaction to Fusarium wilt, and validate

Effect of plant architecture on the responses of canopy temperature and water use to population density in winter wheat Crop Sci. (IF 2.3) Pub Date : 2024-03-10 Guirong Huang, Xinying Zhang, Zhenzhao Wang, Xiaoying Liu, Rui Guo, Fengxue Gu, Enke Liu, Shuying Li, Xiuli Zhong, Xurong Mei
Revealing how plant architecture affects the responses of canopy temperature depression (CTD), water use (WU), and grain yield to population density (PD) in wheat (Triticum aestivum L.) would help explore a water-saving pathway related to managing population. This study was conducted over three consecutive years under rainfed and supplemental irrigation conditions. The flat-leafed Jinmai 47 and upright-leafed

Production innovations to enhance sweetpotato as a food security crop in northern Ghana Crop Sci. (IF 2.3) Pub Date : 2024-03-10 Issah Sugri, Daniel Akansake, Issah A. Abukari, Jan W. Low, Putri E. Abidin, Eric K. Dery, Kwabena Acheremu, Joseph Adjebeng-Danquah, John K. Bidzakin, Mutari Abubakari, Salim Lamini, Edward E. Carey
Sweetpotato (Ipomoea batatas (L) Lam) is prioritized among crops that enhance food security and reduce malnutrition in Ghana. The production is expanding faster than other food crops owing to its superior nutrient composition. This study evaluates integrated approaches to increase on-farm productivity, income, and utilization of sweetpotato. The first part evaluated the agronomic yield performance

Genomewide marker estimates of the level of dominance in maize heterosis Crop Sci. (IF 2.3) Pub Date : 2024-03-10 Patrick K. Sweet, Robenzon E. Lorenzana, Rex Bernardo
Heterosis is the superiority of an F1 hybrid over its parents, and overdominance and dominance are the two main hypotheses for the genetic basis of heterosis. Our objectives were to determine if genomewide marker effects accurately reflect the level of dominance at quantitative trait loci (QTL) and assess the distribution of per-marker estimates of the level of dominance in maize (Zea mays L.). We
