“…Indonesia is among the important world maize producer in South East Asia (Ruswandi et al, 2014). Some of the problems encountered in maize development in Indonesia are the conversion of fertile land under maize production into industrial and residential areas, drought due to global climate change, displacement of maize planting area to marginal land including forest and others.…”

Maize is one of the most important cereals in the world after wheat and rice. Now-a-days, the improvement of maize production is hindered by conversion of agricultural lands into industrial and residential areas. One of the suggested solutions is the production of maize cultivars that can be incorporated in agroforestry systems and can be grown with tree plants such as Albizia. The success of the improvement of new maize cultivars suited to this Maize-Albizia system depends on the availability of genetic variability. Research on the genetic diversity of maize inbred lines that is suited to the agroforestry system with Albizia were conducted in a real forests planted with Albizia tree plants that are around three years old in Cimalaka, Sumedang, West Java, Indonesia. The evaluation of inbred lines was laid on a split plot design with two replications. The main plot consisted of two cropping systems, namely; maize sole cropping system and Maize-Albizia agroforestry system. The subplots were having seventy five inbred lines of maize. The biometric characters included days to anthesis, days to silking, days to harvesting, plant height, length of nodes, plant diameter, chlorophyll content, leaf area index, ear length, ear diameter, number of rows, weight of 1000 seeds and ear weight per plant. Based on the analysis of the main components, in conditions maize sole cropping system, the results showed an Eigen value between 1.08-4.52 which contributes to 67.27% variability, whereas, in the condition Maize-Albizia cropping system, the Eigen value ranged from 1.16-5.37 which contributed to 71.85% variability. Cluster analysis of 75 maize genotypes showed a wide distribution obtaining nine clusters in the maize sole cropping system and five clusters in the Maize-Albizia cropping system. High genetic variability seen in both cropping system greatly supports the development of elite new cultivars of maize that can be utilized in agroforestry systems.

“…Crop Sci., 7 (3): 160-173, 2015 MATERIALS AND METHODS Genetic materials: The genetic materials were evaluated in the study included forty six mutant lines; one hundred and thirty eight single cross hybrids derived from line×tester crosses of fourty six mutant lines to three tester lines and three tester lines. The forty six mutant lines and three tester lines were developed previously by Ruswandi et al (2014). Crosses were made during 2013 and the evaluation of genotypes in experimental trials were performed during the rainy season of 2014 at the experimental plots of Faculty of Agriculture, Padjadjaran University, in Arjasari, Bandung, West Java, Indonesia.…”

Determination of combining abilities and heterotic groupings of parental lines is very important in selecting the mutant lines and to decide breeding strategies for maize hybrid production. Fourty six new mutant lines used in maize breeding programs in Indonesia, were crossed to three tester lines in a lines×testers mating design. The 138 F1 hybrids, the 46 parental lines and 3 tester lines were evaluated at Arjasari, West Java, Indonesia for the following objectives: (i) to analyze line×tester data for maturity and grain yield using GGE for identifying genetic inter-relationships among parents and (ii) to identify the best combinations for maturity and grain yield in maize hybrids. The GGE biplot graphic allowed a rapid and effective overview of General Combining Ability (GCA) and Specific Combining Ability (SCA) effects of the inbred lines, best lines and tester, as well as their performance in crosses. High GCA effect for maturity and grain yield was determined based on Average Tester Coordination function of GGE Biplot. Thus, it was revealed that DR 4 is the best tester for early maturity and DR 6 for grain yield. The maximum best-parent heterosis values and the highest SCA effects resulted from mutants (10, 31, 32, 34, 36, 48) and mutants (5, 7, 10, 32, 34, 36, 37 and 48) crosses to testers (4, 6 and 8) for early maturity and grain yield, respectively. This is potentially useful in maize breeding programs to obtain high-yielding hybrids in areas with the same climate of Indonesia.

“…With the recent advances in science, molecular breeding has become a key approach for crop improvement and maize has benefitted the most. Common approaches employed in molecular research include marker assisted selection, marker assisted backcross, GMO and mutation breeding (Ruswandi et al, 2014;Waminal et al, 2013;Ye et al, 2009;Collard et al, 2005). For a successful molecular breeding, a mapping population developed from two contrasting homozygous or near isogenic parents is used (Xu, 2010;Semagn et al, 2006b;Landi et al, 2005).…”

Maize is the second most important cereal crop in the world after wheat followed by rice. Although, it is among the latest entries in the list of food crops in Africa, maize has attracted much more attention in terms of research and adaptability. Consequently, maize has become the number 1 crop with significant contribution to modern farming and food security in sub-Saharan Africa (SSA). Majority of the population in the region depend on maize as their main source of calories, income and livelihood. Additionally, maize is of global importance as a model organism for advancement of genetic studies. However, maize production in the region is conditioned by complex factors leading to very low average yield compared to other parts of the world. General understanding of tropical maize is one of the key approaches required for improvement of tropical maize in SSA.Here an attempt was made to review various aspects of maize and major advances including the origin, taxonomy, genetics, morphology, physiology, cultural practices, yield potentials, breeding, and production constraints. The information generated could provide useful insights into tropical maize and might contribute towards enhancement of the crop for food security in SSA.
