Finger millet (Eleusine coracana) improvement: Challenges and prospects—A review Plant Breed. (IF 2.0) Pub Date : 2024-04-22 Adane Gebreyohannes, Hussein Shimelis, Jacob Mashilo, Damaris A. Odeny, Taye Tadesse, Chris O. Ojiewo
Finger millet is a climate‐resilient and highly nutritious small grain crop widely grown in the semi‐arid tropics. It has multiple uses, including for food, feed and beverage preparations. However, finger millet is an under‐utilized and under‐researched crop with a mean yield of <1.0 t/ha despite a potential productivity of up to 8 t/ha. The yield gap is attributed to several production constraints

Becker, Bernd Horneburg
Human sensory analysis is the most appropriate method for assessing the flavour of fresh market tomatoes, but it is very labour and time consuming. Therefore, sensory attributes are often neglected in early generations of breeding programmes and genetic studies, although there is a demand for tomatoes with improved flavour. In this study, the recently developed Breeders' Sensory Test was applied to

Conventional and contemporary approaches for drought tolerance rice breeding: Progress and prospects Plant Breed. (IF 2.0) Pub Date : 2023-06-13 C Anilkumar, Rameswar Prasad Sah, Radha Beena, Muhammed Azharudheen TP, Awadesh Kumar, Sasmita Behera, NC Sunitha, SK Pradhan, KR Reshmi Raj, Parameswaran C, BC Marndi, Anil Kumar Singh
Drought is becoming a major threat to rice farming across the globe owing to the depletion of water tables in rice-growing belts. Drought affects rice plants at multiple stages, causing damage at morphological and physio-biochemical levels, leading to severe losses that exceed losses from all other stresses. The amalgamation of conventional breeding methods with modern molecular biology tools and biometrical

Fine mapping and identification of the candidate gene BoPur for purple head trait in cabbage (Brassica oleracea var. capitata) Plant Breed. (IF 2.0) Pub Date : 2023-06-05 Xiaowei Zhu, Jinxiu Chen, Xiang Tai, Min Wang, Yunying Ren, Tianyue Bo
Although purple cabbage becomes more and more popular in recent years, the genetic basis of purple head trait in cabbage has not been well studied. Here, we report the fine mapping and candidate screening of the gene underlying the purple head trait in a cabbage inbred line named G279. Genetic analysis indicated that a single dominant gene, BoPur, controlled the purple head trait. Through fine mapping

Breeding of Lotus japonicus that can overcome adverse seasonal environment by coupling flowering time and abiotic stresses Plant Breed. (IF 2.0) Pub Date : 2023-05-29 Meiru Li, Hongqing Li
Manipulation of floral transition may allow for a free change in the duration of plant vegetative and reproductive growth, thus rendering them to avoid adverse seasonal environmental conditions. In this report, we investigated the effect of the stress-inducible promoter RD29A on driving the rice FT ortholog Hd3a expression in Lotus japonicus ‘MG20’ in response to environmental changes. Constitutive

Breeding evaluation and precise mapping of Fhb8 for Fusarium head blight resistance in wheat (Triticum aestivum) Plant Breed. (IF 2.0) Pub Date : 2023-05-30 Xin Wang, Guoqiang Li, Haiyan Jia, Rui Cheng, Jinkun Zhong, Jinxing Shi, Ruitong Chen, Yixuan Wen, Zhengqiang Ma
The percentage of Fusarium-damaged kernels (FDK) was proposed as a type of Fusarium head blight (FHB) resistance displayed in matured wheat kernels. In this study, Qfdk.nau-7D, a QTL identified in the Wangshuibai genome for its association with FDK, was introduced into FHB-susceptible common wheat line PH691 through marker-assisted selection and backcrossing. Evaluation of two resulted near-isogenic

Optimizing quantitative trait loci introgression in elite rice germplasms: Comparing methods and population sizes to develop new recipients via stochastic simulations Plant Breed. (IF 2.0) Pub Date : 2023-05-30 John Damien Platten, Roberto Fritsche-Neto
This study compared three strategies to develop new recipients for quantitative trait loci (QTL) introgression (background recovery [BG], selective sweep [SS] and breeding value [BV]) in a short-term rice breeding programme (over five breeding cycles). Furthermore, we evaluated two different numbers of recipients (10 and 20) in the introgression process and how they influence the population performance

Evidence of scientific research on organic plant breeding: A bibliometric study Plant Breed. (IF 2.0) Pub Date : 2023-05-30 Bojan Mitrović, Miroslav Zorić, Sreten Terzić, Dalibor Živanov, Petar Čanak, Branko Milošević, Đura Karagić
Use of varieties bred under organic conditions is essential in order to minimize the yield gap between organic and conventional agriculture. The aim of this study was to analyse research publications related to the topic ‘organic plant breeding’ from the Web of Science database using bibliometric science mapping and visualization tools. The number of analysed documents in the bibliographic dataset

Optimization of light/dark cycle in an extended photoperiod-based speed breeding protocol for grain legumes Plant Breed. (IF 2.0) Pub Date : 2023-05-25 Mohammed Mitache, Aziz Baidani, Chafika Houasli, Khadija Khouakhi, Bouchaib Bencharki, Omar Idrissi
The use of high-performing varieties could contribute to increase food legume production and meet the population demand. However, the long process of conventional breeding is a serious limitation that needs further acceleration of genetic improvement. Speed breeding based on extended photoperiod is one of the techniques that allows rapid generation turnover by accelerating the plant life cycle. The

Progress and prospect of developing salt and alkali tolerant rice using hybrid rice technology in China Plant Breed. (IF 2.0) Pub Date : 2023-05-24 Jiayin Liu, Jili Wan, Xiaojia Yin, Xiaozhen Gu, Huide Yin, Meng Yu, Yifang Luan, Rujian Li, Tiezhu Mi, Jiming Li
Soil salinization and alkalization are important abiotic stresses that affect crop growth and yield. Development of salt and alkali tolerant varieties is still dominated by the following conventional breeding method: The salt and alkali tolerant traits from screened germplasm are introduced into elite varieties by means of hybridization and backcrossing. In recent years, the breeding of salt and alkali
