Structural features of a cytoplasmic male sterility source from Helianthus resinosus, CMS RES1

  Comparisons in the structural organization of mitochondrial DNA between a cytoplasmic male sterility source from Helianthus resinosus (CMS RES1) and HA89 fertile line have been performed surrounding coxIII and atp9 genes. Differences have also been recognized by PCR analyses between HA89 (CMS RES1) and either HA89 (CMS PET1) or HA89 (CMS MAX1), indicating that the molecular basis of their...

Variability in sucrose content at grand growth phase in tissues of Saccharum officinarum × Saccharum spontaneum inter-specific hybrid progeny

    The variability for sucrose content in existing commercial sugarcane germplasm is not large and hence crosses were made between two Saccharum officinarumclones, ‘Gungera’ (cross I) and ‘Keong’ (cross II) with high sucrose content and a clone of Saccharum spontaneum ‘SES 603’ with low sucrose content. A high sucrose commercial var. CoS 8436 was...

Combining the yield ability and secondary traits of selected cassava genotypes in the semi-arid areas of Eastern Kenya

  Despite the importance of cassava for food security in semi-arid areas of Kenya, there is a lack of information regarding gene action determining yield of local varieties. Therefore the objective of this study was to estimate the combining ability for yield and associated secondary traits by crossing popular local varieties with some varieties from IITA using a NC II mating design. The F1 progenies...

Multivariate analysis of genetic divergence in twenty two genotypes of groundnut (Arachis hypogaea L.)

  Twenty-two groundnut genotypes collected from different germplasm centers were cultivated in Botanical nursery of the Lagos State University Ojo-Campus during the raining season of 2009. The data collected on 33 characters were subjected to multivariate analysis to study the variability within the genotypes and to determine the efficiency of the methods in classifying genotypes. The first three axes each...

Screening rice genotypes for drought resistance in Egypt

  A series of experiments were conducted under normal and drought conditions to examine the magnitude of yield response of diverse genotypes to drought stress and to identify traits that may confer drought resistance. Thirty-three local and exotic rice entries including 18 Egyptian genotypes (selected from Fn generation of the breeding for drought tolerance program, Rice Research and Training Center, Egypt),...

Growth and yield of cucumber (Cucumis sativus L.) as influenced by farmyard manure and inorganic fertilizer

  The growth and yield of Ashley variety of cucumber in response to the effect of farmyard manure and inorganic fertilizer NPK 20:10:10 was evaluated at the Teaching and Research Farm of the Ambrose Alli University, Ekpoma, Nigeria Lat 6°45’N and long 6°08’E. The farmyard manure was applied at the rates of 0, 5 and 10 t/ha and the inorganic fertilizer at 0, 100, 200, 300 and 400 kg/ha. The...
