Agro-morphological variability of shea populations (Vitellaria paradoxa CF Gaertn) in the Township of Bassila, Benin Republic

Shea (Vitellaria paradoxa CF Gaertn) is a multipurpose forest tree species. This is one of the most integrated species in the cropping systems in the central and northern regions of Benin. It is also an important source of income for the population. Observations were made on some shea trees randomly selected in three vegetation types namely forests, fallows and farms. Data collection on quantitative and qualitative...

Optimization of micropropagation protocol for three cotton varieties regenerated from apical shoot

The need for alternative strategies to obtain transgenic cotton via apical shoot was necessitated due to the recalcitrance of cotton regeneration from somatic embryogenesis, this has greatly slowed down the development of transgenic cottons. To this effect, an optimized regeneration system from apical shoot was developed for three varieties of cotton. Ninety-five percent seed surface sterility was observed in seed...

Morphological diversity and association of traits in ethiopian food barley (Hordeum vulgare l.) landraces in relation to regions of origin and altitudes

One hundred and two barley accessions and five checks were evaluated using augmented design consisting of four complete blocks in 2012 main cropping season at holetta agricultural research center. Ten quantitative and six qualitative characters were recorded. Analysis of variance showed significant difference (p<0.01) among accessions for plant height, awn length, peduncle extrusion, thousand seed weight, number of...

Correlation, path coefficient analysis and heritability of grain yield components in pearl millet (Pennisetum glaucum (L.) R. Br.) parental lines

Twenty four parental lines of pearl millet A/B pairs developed jointly by Lake Chad Research Institute (LCRI), Maiduguri and International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Kano during 1997 to 1999 were evaluated along with a seed parent (ZATIB) across five locations to determine yield and yield component relationships, heritability estimates as well as genetic advance. Correlation...
