The genetic studies were carried on accessions of the Andropogon gayanus-Andropogon tectorum complex (Poaceae) in southwestern Nigeria to determine the chromosome numbers and meiotic dynamics in the species. This involves meiotic chromosome and pollen studies using standard procedures. Studies on the morphology and meiotic behaviour of collections...

Morphological studies were carried out on collections of the Andropogon gayanus-Andropogon tectorum complex from Southwestern Nigeria to provide full characterization of accessions of the two species and elucidate their population dynamics. Morphological data from selected accessions of A. gayanus and A. tectorum from different parts of Southwester...

An investigation of their reproductive biology w...

Morphological studies were carried out on collections of Andropogon gayanus-Andropogon tectorum complex from Southwestern Nigeria. This is with the view to providing full characterization of the accession of the two species of Andropogon and elucidating their population dynamics. Morphological data from selected accessions of A. gayanus and A. tect...

morphological characteristics of the vine, leaf and tuber and their appendages was constructed. Multiple vines was found to be about 50% in occurrence among the cultivars. It is a valuable agrobotanical character which conditions multiple tubers and can ensure the survival of at least one vine per hill in the event of drought. Multiple tubers from...

This study explored the underlining reproductive factors that cause sterility in rice, using hybrids obtained from crosses among landrace selections and improved varieties. The study was carried out between 2016 and 2018. Nine landrace cultivars and two improved varieties were involved in the hybridization experiment. Among the 17 putative hybrids...

Foliar epidermal studies were carried out on accessions of Andropogon gayanus-Andropogon tectorum complex collected in Southwestern Nigeria with a view to providing additional characters of the two species of Andropogon to enhance the understanding of the taxonomic relationship between the two species. The epidermal preparation of the adaxial and a...

The genus Dioscorea comprises of economically-important plant species known for their starch throughout the world; it is also a major source of food and income in Africa. The most important Dioscorea species cultivated and consumed in the West Africa belt include D. cayenensis, D. rotundata and D. alata. The plant materials used in this study were...

This study was initiated to restore the genetic resources of yam which had been decimated in a core yam-producing community in Ekiti State, Southwestern Nigeria. Twenty cultivars, consisting of Dioscorea rotundata, D. cayenensis, D. alata, and D. dumetorum were identified, collected, characterized and multiplied using an On-farm Participatory Metho...

Background: Popular rice accessions cultivated in Abakaliki, Nigeria, were characterized for agro-morphological traits performance and assessed for genetic diversity as prerequisites for future breeding programmes. Objectives: The study was intended to assess the yield potentials of the rice accessions and identify molecular markers with potentials...

Two landraces of rice, AWGUII-04 and IJ-124, were characterised and assessed for phenotypic variability, heritability, genetic advance and modes of inheritance of some primary yield and drought-tolerance traits. The target traits for yield were a percentage of filled spikelets, plant form, tillering, and for drought tolerance, leaf rolling, ratooni...

This paper is about the population dynamics in the A-genome complex of the genus Oryza. It is specifically about gene exchange among O. longistaminata (wild), O glaberrima(cultivated turned wild) and the cultivated O. sativa. The first two varieties make interphases with cultivated rice in Jebba and they generate hybrid swarms. The paper discusses...

A cross was made between ERINMO 14 and OGIDE DWARF representing a cross between brown caryopsis and white caryopsis, respectively. the F1 seeds were brown. The F2 show that caryopsis colour is conditioned by a set of duplicate genes giving rise to 5 character states. The ripened hull colour was found to be dependent on the colour of the caryopsis;...

The relationship in the ploidy levels, pollen grain and epidermal parameters among four Physalis species (P. angulata Linn., P. peruviana Linn., P. micrantha Link. and P. pubescens Linn) present in Nigeria was investigated from meiotic chromosome, foliar epidermal and pollen grain studies using standard techniques. The study revealed that P. angula...

Mitotic chromosomes from root tips of four Nigerian Physalis species were investigated using standard cytogenetic methods. P. angulata has chromosome number of 2n = 48 with karyotypic formula of 2M + 5m + 16sm + 1st, while P. micrantha, P. peruviana and P. pubescens showed the same chromosome number of 2n = 24 with karyotypic formulae of 1M + 1m +...

Interspecific reciprocal crosses among four Nigerian Physalis species (Physalis angulata, P. micrantha, P. pubescens and P. peruviana) were carried out by transferring desired pollen grains to ovalate parents, bagged and labelled to prevent contamination by external pollen grains and for easy identification. Pollen cells of the F1 hybrid combinatio...

Morphological, anatomical and chromosome studies of Hyophila crenulata C, Mull. Ex Dus, Thuidium gratum (P. Beauv) Jaeg., Barbula lambarenensis P. Vard.. Stereophyllum nitense Mitt. and Bryum coronatum Schwaegr from Nigeria, were carried out with a view to bridging some knowledge gaps that exist in their characterization and providing insightful in...

Breeding for drought tolerance based on direct selection for high grain yield under drought has been hindered by the complex nature of drought tolerance mechanisms and the approaches used. Molecular marker-based approaches are a promising alternative. In this study, 30 rice (Oryza sativa L.) accessions cultivated in Nigeria were screened in a green...

The morphotypes and chromosome numbers of Euphorbia hyssopifolia and Euphorbia heterophylla from Ile-Ife, Nigeria are reported for the first time. Mitotic studies carried out on both species revealed a diploid chromosome number of 2n = 12 and 2n = 28 respectively. The results indicate that the two Euphorbia species studied belong to the members of...

Background: The flower bud exudates of Spathodea campanulata is commonly used as a local eye drop in Nigeria and is anecdotally claimed to improve vision. This study evaluated the anti-cataract activity of Spathodea campanulata (SPCM) flower bud exudates against cataractogenesis using rat lenses. This was done with a view to providing empirical sci...

This study investigated branching pattern, ecology of occurrence, palynology, cytology and phenology of Monodora tenuifolia using standard techniques. The branching pattern determines the shape of the canopy, which may be irregular when growing in the shade, or round when growing in the open. The pollens are tetrads, 10.15 µm in diameter, with poll...

Thirty-five (35), wild (5) and cultivated (30) Sorghum bicolor germplasms were collected from 5 different agro-ecological zones in Nigeria. Proteins were extracted from six weeks old fresh leaves (1.0 g) with 10ml of 0.85% (w/v) sodium chloride (NaCl) solution, filtered and followed by centrifugation at room temperature at 3,000 rpm for 10 min. The...

This paper reports progress in the reforestation project at the Obafemi Awolowo University as a case study of one site that has been planted with Elaeis guineensis at a spacing of 78 m x 39 m and managed under the minimally-invasive strategy for three years. A total enumeration of site shows that there are 54 species in 19 families in site JSQ1 tha...

The study reports the result of analysis of chromosomes of Vigna subterranea performed in the mitotic prometaphase and metaphase stages using conventional techniques. The somatic chromosome study was done using the shoot meristem as the root tips persistently showed very low mitotic indices. The result revealed somatic chromosome number of 2n = 22....

Between 1986 and date, land races of rice (Oryza satwa Linn .) have been collected from rice-growing areas of Nigeria (Okposi in Abia state, Awgu in Enugu state, Ofada in Ogun state, Ijesa-Isu and Igbemo in Ekiti state, and Erinmo in Osun state) and they were characterized for their agronomic attributes. Peasant rice holdings were studied for 4 ye...
