Red clover (Trifolium pratense L.) is a globally significant forage legume in pastoral livestock farming systems. It an attractive component of grassland farming, because its high yield and protein content, nutritional value ability to fix atmospheric nitrogen. Enhancing role further sustainable agriculture requires genetic improvement persistency, disease resistance, tolerance grazing. To help address these challenges, we have assembled chromosome-scale reference genome for red clover. We...
Red clover (Trifolium pratense L.) is a versatile forage crop legume, which can tolerate variety of soils and suitable for silage production winter feed grazing. It one the most important legumes in temperate livestock agriculture. Its beneficial attributes include ability to fix nitrogen, improve soil provide protein rich animal feed. however, short-lived perennial providing good biomass yield two or three years. Improved persistency thus major breeding target. Better water-stress tolerance...
Root and tuber crops are a major food source in tropical Africa. Among these several species the monocotyledonous genus Dioscorea collectively known as yam, staple crop that contributes enormously to subsistence socio-cultural lives of millions people, principally West Central Yam cultivation is constrained by factors, yam can be considered neglected "orphan" would benefit from improvement efforts. However, lack genetic genomic tools has impeded this crop. To accelerate marker-assisted...
Abstract Crop landraces have unique local agroecological and societal functions offer important genetic resources for plant breeding. Recognition of the value landrace diversity concern about its erosion on farms led to sustained efforts establish ex situ collections worldwide. The degree which these succeeded in conserving has not been comprehensively assessed. Here we modelled potential distributions eco-geographically distinguishable groups 25 cereal, pulse starchy root/tuber/fruit crops...
White clover ( Trifolium repens L.) and red T. pratense are the most important legumes of temperate pastures. The former is used largely in systems based around sheep or cattle grazing grown together with a companion grass. Breeding aims to optimize white contribution sward. This means that yield per se not aim but rather take full advantage benefits clover; particular, nitrogen fixation, high protein content, digestibility, mineral content intake. objective an agronomically and, as far...
The International Institute of Tropical Agriculture maintains the world's largest collection cowpea germplasm over 15,000 accessions. A sub-set 298 lines from loosely composed mini core 370 landraces were genotyped based on genotyping by sequencing (GBS). Ward's minimum variance hierarchical cluster analysis, model-based ancestry analysis and discriminant principal component (DAPC) carried out this sub-set. Three clusters identified different clustering methods. Principal further supported...
In plant breeding and agricultural research, biplot analysis has become an important statistical technique. The goal of this study was to find the winning genotype(s) for test settings in a part Southwest region Nigeria, as well investigate nature extent genotype × environment interaction (GEI) effects on Bambara groundnut (BGN) production. experiment carried out four environments (two separate sites, Ibadan Ikenne, two consecutive years, 2018 2019) with ninety-five BGN accessions. According...
Adopting underutilized legumes in tackling food security is essential, especially this era of climate change. Underutilized are embedded with inherent potentials such as the ability to survive extreme conditions (such temperature, drought, pH, saline, etc.), high nitrogen-fixing potential, weed and disease control ability, nutrient status. can improve yield companion crops an intercropping system a subsequent crop (due their residual effects). They possess symbiotic non-symbiotic organisms...
Abstract Perennial ryegrass and perennial ryegrass/white clover permanent dairy pastures are compared with respect to productivity, environmental impact financial costs in nitrate vulnerable zones (NVZ) the UK. With appropriate management, utilisation of recommended white cultivars, is likely stabilise at around 20% total dry matter production a mixed pasture. Plant milk from pasture be similar that receiving 200 kg N ha −1 annum 70% obtained supplied 350–400 . Nitrate, phosphorus methane...
Many people in sub-Saharan Africa suffer from protein malnutrition; this results negative health and economic impacts. Winged bean ( Psophocarpus tetragonolobus (L.) DC.) is a tropical underutilized legume with beneficial nutritional characteristics such as high content, which may help to alleviate these problems. The proximate composition (fat, moisture crude protein, ash, carbohydrate) antinutrient (tannin phytate) level of winged seeds tubers were determined using 50 accessions. In the...
Biplot analysis has emerged as a crucial statistical method in plant breeding and agricultural research. The objective of this research was to identify the best-performing genotype(s) for environments three distinct regions Nigeria while also examining characteristics magnitude genotype–environment interaction (GEI) effects on yield Bambara groundnut (BGN). study conducted Ibadan, Ikenne, Mokwa, utilizing sample 30 accessions. BGN found be significantly affected by accessions, environment,...
Abstract Underutilized, or orphan legumes, are widely distributed across farming landscapes in sub‐Saharan Africa (SSA) but often have low yields and do not fulfill their potential due to very limited research, breeding, development, marketing, awareness of benefits. These advantages include nutritional quality climate resilience. In this review, we focus on Bambara groundnut, African yam bean, Kersting's groundnut. Knowledge the challenges rewards exploiting them will provide opportunities...
Bambara groundnut (BGN) is a drought-tolerant crop majorly cultivated in sub-Saharan Africa. Due to lack of extensive research, marginalization, awareness, and available fund among others, this crop's improvement has been limited. The development depends on evaluation selection unique stable breeding lines different environments. This study aims estimate genetic diversity using morphological traits at locations 95 accessions BGN collected from the Genebank International Institute Tropical...
Abstract African yam bean (AYB) is an underutilized legume with significant potential for food security in sub-Saharan Africa, yet limited research exists on optimizing its seed yield through selective breeding. In this study, the (SY) performance and relative importance of some yield-related traits SY AYB were assessed. One hundred ninety-six accessions evaluated 2 years three agro-ecologies Nigeria. The experimental design was a 14 × lattice replicates. Data recorded 13 SY-related traits....
Aims: To identify the genotype(s) most suited for test environments in Nigeria and to understand nature of genotype-by-environment interaction (GEI) effects on AYB production. Study Design: Multi-environment trials combined with GGE biplot analysis explore genetic interactions determine adaptability stability African yam bean accessions across diverse environments. Place Duration Study: The research was conducted over four environments, Umudike (rainforest) Ibadan (derived savanna), during...
