One hundred and sixty accessions representing global germplasm of guinea grass (Panicum maximum Jacq.), an important apomictic (aposporous) fodder crop, were subjected to study on reproductive diversity in apomictic seed development utilizing ovule clearing and flow cytometric seed screen (FCSS). Single seed FCSS of selected 14 tetraploid and five hexaploid(More)
This is the first report on the development of interspecific hybrids between T. alexandrinum and T. resupinatum, using embryo rescue. T. resupinatum is an important donor species for traits such as resistance to root and stem rot diseases, and tolerance to alkalinity for the potential improvement of T. alexandrinum. T. alexandrinum, as female parent, was(More)
The embryo rescue technique was successfully used to raise hybrids between Trifolium alexandrinum and T. constantinopolitanum. As a result of its narrow genetic base, genetic improvement in Egyptian clover (syn. Berseem; T. alexandrinum), an important fodder crop in tropical and subtropical countries, is hampered, thereby making it imperative to introduce(More)
The genus Trifolium comprises of 290 annual and perennial species of which the species such as T. repens, T. hybridum, T. pratense, T. ambiguum, T. resupinatum, T. alexandrinum are economically important. Boundaries between species in many cases have been difficult to define because of wide range of diversity caused by primary polymorphism. Hence, inter-(More)
The study deals with similarity among 25 species of the genus Trifolium represented by 134 accessions. Clustering of the species based on isozyme banding pattern of five enzymes revealed that T. repens was distinctly different from other species. T. repens and T. retusum formed independent clusters. The group of species comprising of T. pratense, T.(More)
In vitro regeneration of Trifolium glomeratum, a leguminous forage species, was attempted through leaf, petiole, cotyledon, hypocotyl, collar and root explants and two media combinations. Root and collar explants showed no callus induction. Medium with 0.05 mg dm−3 α-naphthaleneacetic acid (NAA) and 0.10 mg dm−3 N6-benzyladenine (BA) was more effective for(More)
The European Union (EU) Seventh Framework Programme (FP7) project Spectrum [12] set out to develop a freight vehicle which would facilitate the exploitation of the low density, high value (LDHV) goods market. Key to the performance criteria for the vehicle were: increased speed to enable mixed running with passenger services; improved ride quality to avoid(More)
Isozyme banding pattern was studied in Guinea grass (Panicum maximum Jacq.), a widely cultivated grass having good fodder value. Similarity among 63 accessions collected from diverse sources was worked out using five enzyme systems (SOD, GOT, ACP, Esterase and Peroxidase) following horizontal starch gel electrophoresis. Biochemical markers such as isozymes(More)
New tri-species hybrids (GOS) in the genus Pennisetum involving the cultivated species pearl millet (P. glaucum L.) and two wild species, viz. P. squamulatum Fresen and P. orientale L. C. Rich, are reported. Six hybrid plants were recovered after crossing a backcross hybrid (2n = 3x = 23, GGO) between P. glaucum (2n = 2x = 14, GG) and P. orientale (2n = 2x(More)
