Description/Abstract

Due to the low biological value of proteins of common maize, it was reinitiated breeding for high protein quality maize (HQPM) using three genetic systems, namely: opaque-2 gene, endosperm modifier genes and enhancer genes, which are increasing lysine and tryptophan content in opaque-2 background In order to alleviate effect of abiotic and biotic stress factors, the genotypes with tolerance to those factors were included. Genetic resources originating from North, Central and South America, then West, Central and Southern Africa and gene bank of Maize Research Institute “Zemun Polje” were used. Combining breeding approaches in selection of genetic resources, field plot techniques and laboratory analysis, it was created large number of early QPM varieties, inbred lines and hybrids with modified endosperm and high yield potential under poor and good growing conditions. Created lines exhibited high combining ability in conventional and non-conventional hybrids. Yield trials showed that QPM hybrids are competing with commercial hybrids of common maize.

Description/Abstract

Maize is the principal crop and major staple food in the most African and South American countries. The main problem in human nutrition in developing countries, and in livestock feed in developed countries, is insufficient production and poor quality of cereal proteins. In the case of maize, due to the very low content of essential amino acids lysine and tryptophan in grain endosperm, biological value is very low, which is main limiting factor of common maize in human nutrition and feeding of monogastric animals. Quality protein maize (QPM) can help in solving of this problem. Maize production also faces serious constraints caused by agro-ecological conditions and poor socio-economic situation. To alleviate the effect of the constraints, selected genotypes with more desirable traits and appropriate field-plot techniques to create multiple-stress conditions, were used. It was found that, in downy mildew nursery distance up to 35 m from spreader plot is providing sufficient down load of spores for plant infection, provided that the testing breeding materials are planted towards to down-stream direction of the dominant wind. Using these breeding approaches large number of early, white and flint synthetics, composites and inbred lines were created with resistance or tolerance to downy mildew (DMR), maize streak virus (SR) and drought (DT). Created genotypes exhibited very good kernel modification and yield potential under low and normal inputs. In the case of synthetics and composites, besides tolerance to multiple stress factors, they were competing in yield with local QPM and normal maize checks. In the case of created inbred lines high combining ability was exhibited both in non-conventional and conventional maize hybrids. Trial data revealed that in the most cases the best entries were over-yielding the best checks.

Description/Abstract

The incrementation of lysine, tryptophan and maize protein nutritional value in locals where maize is staple food could contribute significantly to improving the population nutritional status. The objective of this study was to estimate variance and average components related to the maize protein quality based on tryptophan and grain yield analysis, and to select from the early generations progenies which best complement with the tester for both characters. The laboratory analyses were carried out by using colorimetric reactions and the statistical analyses were based on mixed model. The experiment was set out in partially balanced square lattice with 144 treatments, two replications and 12 blocks. The estimations, associated with the assessed treatment performances made it possible to infer that both populations are promising for recurrent selection and suggested good experimental precision. The selective accuracy demonstrated the possibility of obtaining gains by selecting in both characters. For tryptophan content, the specific combining ability presented small magnitude value due the qualitative inheritance and, the additive effects might have been more important. The shrinkage effect in grain yield was more noticeable than the tryptophan content. Over 25% of the progenies contributed positively to the tryptophan content and only 3.65% to grain yield.

Description/Abstract

Cotton (Gossypium hirsutum L.) is an important cash crop for small-scale farmers in Mozambique. The yield is dependent on various factors of plant management, and this can be affected by variations in plant density. In Mozambique the cotton crop is mainly growed in plant and row space arrangement corresponding to 50,000 plants per hectare, which is considered low resulting in low cotton yielding.The goal of this study, was to evaluate the effect of plant density in cotton yield, Gossypium hirsutum L. The experiment was conducted in Namialo village, in a randomized complete block design with four replications in a split-plot, where the main plot was distance between the plants within the rows (15, 20, 25, 30 cm) and distance between the rows (50, 75, 100 cm) as subplots randomized in each plot, making plant from 33000 to 133000 plants per hectare. Results of this experiment showed no significant interaction between the distance between the rows and plants on cotton yield, number of bolls per plant and plant height. In addition, as the distance between the plants increased, the number of bolls per plant also increased. This experiment empathize that the combination of 70 cm between the rows and 20 cm between the plants, with a total density of about 71400 plants per hectare resulted in a highest yield.

Description/Abstract

Pigeon pea is one of the important legumes for export and domestic consumption in Mozambique. The objective was to evaluate the performance of the genotypes and to stratify environments for agricultural zoning and subsequent recommendation. The experiments were conducted in the northern region of Mozambique, to evaluate grain yield, in randomized blocks, with three replications and 20 long-maturing genotypes, in the 2016/2017 season in four environments. The results were obtained through the joint analysis and the complementarity of information from the biometric methodologies of Eberhart and Russell, Centroid and GGE-biplot aiming at better use of the significant GXE interaction. A mega-environment (Nampula and Namapa) was observed, of which Namapa district was the most discriminating and representative. The genotypes suggested for a recommendation as cultivars showed average performance. The ICEAP01490 genotype was of specific adaptability to favorable environments (Nametil and Namapa district) and high stability, is recommended for medium to high technology environments and the ICEAP01498 genotype was of specific adaptability to unfavorable environments (Nampula and Montepuez district), is recommended for low technology environments. The ICEAP01409 genotype can be indicated for a general recommendation. The ideal genotype with high mean, general adaptability and high stability was not observed, suggesting evaluations in more environments.

Description/Abstract

Maize (Zea mays L.) is the most important staple food in Mozambique but its production is facing constraints such as drought, floods, cyclones, soil infertility, diseases, and pests, being drought one of the most limiting factor. To meet the challenge of producing under such conditions, it is important to invest on breeding programs to produce maize varieties that are resistant and adaptable to the present agroecological conditions. Maize is a C4 plant that evolved a biochemical mechanism of concentrating CO2 to overcome the oxygenase activity of Rubisco, which makes C4 plants photosynthetically more efficient than C3 plants. We Hypothesized that the levels of enzymes involved in photosynthesis (PEPC, PPDK, NADP-ME, and RubisCO) and their Post Translational Modifications (PTMs) correlate with the photosynthetic capacity of maize plants under drought stress. To examine their potential role as molecular markers for drought tolerance, we will make use of cutting-edge proteomics techniques. We will also provide data on agronomic performance and nutritional quality of the maize grain grown under the Greenhouse conditions in ITQB and under the local practices and agroecological conditions in Mozambique. We will use maize B73 as a control to test three varieties from Mozambique: Matuba, ZM523, and ZM 309. The main goal of the present project is to contribute with knowledge and important data that can be added to Mozambique’s maize breeding programs.
