Napier grass (Pennisetum purpureum Schumach.) is a fast-growing perennial native to Sub-Saharan Africa that widely grown across the tropical and subtropical regions of world. It multipurpose forage crop, primarily used feed cattle in cut carry feeding systems. Characterization diversity studies on small collection grasses have identified moderate level genetic variation highlighted availability some good agronomic traits, particularly high biomass production, as crop. However, very little...
Napier grass is the most important perennial tropical native to Sub-Saharan Africa and widely grown in subtropical regions around world, primarily as a forage crop for animal feed, but with potential an energy wide range of other areas. Genomic resources have recently been developed that need be deployed genetic improvement molecular dissection agro-morphological feed quality traits. From diverse set genotypes assembled from two independent collections, subset 84 (although small population...
Abstract Napier grass is an important tropical forage-grass and of growing potential as energy crop. One-hundred-five accessions, encompassing two independent collections, were subjected to genotyping by sequencing which generated a set high-density genome-wide markers together with short sequence reads. The reads, averaging 54 nucleotides, mapped the pearl millet genome closest genes annotation information used select candidate linked key forage traits. 980 highly polymorphic SNP markers,...

Genome-wide markers, generated using DArTSeq platform mapped onto Setaria...
In the semi-arid and arid environments of Sub-Sharan Africa, forage availability throughout year is insufficient highly limited during dry seasons due to precipitation. Thus, identification drought stress-tolerant cultivars one main activities in development programs. this study, Napier grass (Cenchrus purpureus), an important crop Eastern Central Africa that broadly adapted produce across tropical environments, was evaluated for its water use efficiency production performance under field...
At the International Livestock Research Institute (ILRI), Addis Ababa, Ethiopia, 171 germplasm accessions of Napier grass were studied using 20 SSR markers with objective assessing allelic richness and genetic diversity collections held at ILRI Brazilian Agricultural Corporation (EMBRAPA), to determine distinct be introduced enhance in each genebank collections. A total 148 alleles observed whole collection, which 140 93 EMBRAPA collections, respectively. Fifty-five 8 found unique...
Essential (EOs) can be considered as an alternative tool to control weeds, they are eco-friendly and safe bioherbicides. Based on their herbicidal efficacy against coffee weeds in the prescreening under in-vitro, lath-house field experimentations, five aromatic plants namely, Cymbopogon citratus, C. martinii, winterianus, Eucalyptus citriodora Thymus schimperi were selected identify chemical composition using Gas Chromatography-Mass Spectrometry. The chromatographic analysis revealed...
Buffelgrass (Cenchrus ciliaris L.) is an important forage grass widely grown across the world with many good characteristics including high biomass yield, drought tolerance, and adaptability to a wide range of soil conditions agro-ecologies. Two hundred five buffelgrass accessions from diverse origins, conserved as part in-trust collection in ILRI genebank, were analyzed by genotyping-by-sequencing using DArTseq platform. The genotyping generated 234,581 single nucleotide polymorphism (SNP)...
Pea is one of the most important legume crops whose production constantly threatened by field and storage pests diseases. Developing insect resistant transgenic pea plants through Agrobacterium-mediated transformation a promising solution to maintain crop yield. However, efficiency still low. Therefore, there was an attempt enhance optimizing infection time, co-cultivation period in vitro regeneration system. Transformation performed using segments embryonic axes from mature seeds (Pisum...
Rhodes grass (Chloris gayana Kunth) is one of the most important forage grasses used throughout tropical and subtropical regions world. Enhancing conservation use genetic resources requires development knowledge understanding about existing global diversity species. In this study, 104 accessions, held in trust ILRI genebank, were characterized using DArTSeq markers to evaluate population structure, develop representative subsets, collection. The genotyping produced 193,988 SNP 142,522...
The production of traditional cool season grasses in temperate regions is becoming hampered during summer seasons due to water deficit. Thus, incorporating use efficient warm annual are generally considered fill the gap forage reduction that would offer considerable flexibility and adaptability respond demand. Teff (Eragrostis teff Zuccagni) Trotter) is, a C4 drought tolerant grass primarily grown for grain production, recently gaining interest particularly season. Previous reports have...
Transgenic pea lines transformed with the cry1Ac gene were characterized at molecular (PCR, RT-PCR, qRT-PCR and immunostrip assay) functional levels (leaf paint insect feeding bioassays). The results showed presence, expression, inheritance functionality of introduced transgene different progeny levels. Variation in expression was observed among transgenic lines. In bioassay studies using larvae Heliothis virescens, both larval survival plant damage highly affected on plants. Up to 100 %...
