Conference Paper 2003

Autor: Tenkouano, A. Hughes, J. Dahal, G. Pillay, M.

The genetic improvement of banana and plantain has focused on breeding for resistance to black sigatoka. This has been quite successful, but the distribution of improved hybrids has been impeded by the outbvreak of Banana streak virus (BSV). Integration of viral sequences in Musa genomes make it ...

Between 1991 to 1996, more than 50 Musa hybrids and 10 landraces were evaluated under field and screenhouse conditions for virus symptoms resembling those caused by banana streak badnavirus (BSV). The symptoms included chlorotic streaks, leaf deformation, stunting, cigar leaf death, distortion of...

Various virus‐like symptoms were recorded on field‐grown cowpea(Vigna unguiculataL. Walp) and pea(Pisum sativumL.) during 1989–1990 at the experimental farm of the Institute of Agriculture and Animal Sciences (IAAS), Rampur, Chitwan valley, in the central terai plains of Nepal. The causal agent(s...

Micropropagated plants of 36 Musa genotypes with diverse genetic backgrounds, including 14 tetraploid plantain (TMPx) and banana (TMBx) hybrids, were evaluated for their response to banana streak badnavirus (BSV) infection under three environments from 1995 to 1997 in Nigeria. The characteristics...

Monitoring of banana streak badnavirus (BSV) antigens and symptoms in naturally BSV‐infected plantain and banana (Musa spp.) plants showed a great variation in symptom expression, distribution and relative concentration of BSV between and within plants. Expression and distribution of symptoms was...

Streak disease of banana and plantain caused by banana streak virus (BSV) was first reported in the Ivory Coast in 1974 and occurs in at least 16 countries in Africa. Based on genomic characteristics, BSV has been shown to be a member of genus Badnavirus. Efficient and reliable diagnostic methods...

A survey of rice fields during the main growing seasons in 81 locations from 21 districts of the southern Terai region of Nepal indicated that rice tungro was primarily restricted to the Hardinath (Janakpur) and (Parwanipur (Bara) regions. The tungro incidence in Hardinath ranged from 17% to 51% ...

The DNA genomes of isolates of rice tungro bacilliform virus from Bangladesh, India, Indonesia, Malaysia and Thailand were cloned and compared with that of the type isolate from the Philippines. Restriction endonuclease maps revealed differences between the isolates and cross-hybridization showed...
