ABSTRACT
Basil is known as ‘Herbe Royale’ which has potential as a source of antibacterial compounds which emphasizing in the importance of humans’ health and food manufacturing in the future. This study evaluated the antibacterial activities of the methanol extracts of two Ocimum spp. which include Ocimum basilicum L. and Ocimum basilicum var. purpurascens. These methanol extracts were tested against four pathogenic bacteria; Bacillus cereus, Staphylococcus aureus, Escherichia coli and Salmonella typhimurium. Significant antibacterial activity was shown for these tested crude extracts in agar disc diffusion, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) tests. The methanol extracts of these basil species were most effective against Gram-positive bacteria and least effective against E. coli which is the Gram-negative bacteria in agar disc diffusion method. The sweet basil showed highest diameter inhibition zone with 16.33 ± 1.53 mm against B. cereus while the red rubin basil exhibited 11.33 ± 1.15 mm against S. aureus. Minimum inhibitory concentration and minimum bactericidal concentration were assessed by microdilution method and the results showed that the extracts of O. basilicum L. and O. basilicum var. purpurascens strongly inhibited the growth of all the tested pathogens, especially the Gram-positive strains, whereas the moderate inhibition activity against Gram-negative strains. The result may suggest that, these two basil extracts possess compound with good antibacterial properties that can be used as antibacterial agents in the search for new drugs.

ABSTRACT
The objective of the research was to select short-duration pigeon pea genotypes with high yield, stability and broad genotypic adaptability for northern region of Mozambique using REML/BLUP mixed model. Twelve short-duration genotypes were evaluated in twelve environments from combinations of locations and years: Nampula (2016, 2017 and 2018), Ribáuè (2016), Mogovolas (2016, 2017 and 2018), Namapa (2016, 2017 and 2018) and Montepuéz (2017 and 2018), in a randomized block design with three replications. The genetic parameters were estimated by the mixed model of restricted maximum likelihood (REML) and best linear unbiased prediction (BLUP). The significance of the deviance analysis effects was tested by the likelihood ratio test, considering the χ2 distribution. The selection genotypic strategies were based on the predicted genetic values free of interaction (µ + g), with local interaction (µ + g + ge), mean of environments (µ + g + gem), and harmonic mean of relative performance (MHPRVG). Different genotypic responses were observed for genotypes x locations and genotypes x locations x years interactions. The REML/BLUP mixed model allowed the selection of the short-duration pigeon pea genotypes ICEAP 01107/5, ICEAP 01107/8 and ICEAP 01284, simultaneously for yield, stability and broad genotypic adaptability for northern region of Mozambique.
