Breeding of speciality maize for industrial purposes

The breeding programme on speciality maize with specific traits was established at the Maize Research Institute, Zemun Polje, several decades ago. The initial material was collected, new methods applying to breeding of speciality maize, i.e. popping maize, sweet maize and white-seeded maize, were introduced. The aim was to enhance and improve variability of the initial material for breeding these three types of maize. Then, inbred lines of good combining abilities were developed and used as components for deriving new superior popping maize hybrids, sweet maize hybrids and white-seeded maize hybrids. Breeding was aimed at the increase of the popping volume of new inbred lines and hybrids of popping maize, then at the improvement of quality of popped kernels - flakes, and at yield increasing. Furthermore, the aim was to improve quality of sweet maize for different purposes, industrial processing and consumption as fresh food and also to improve yield and quality of white-seeded maize. As a result of such breeding, 28, 11 and 9 sweet maize, popping maize and white-seeded maize hybrids were released, respectively.

Physiological Quality

Abstract: Viability and vigor of seeds are physiological attributes influenced by a myriad of factors including the genotype. Biochemical profiling of maize seeds and its correlation with their physiological quality is of crucial importance in breeding programs that the aim is seeds of better quality. The main goal of this study was to analyze the genetic diversity among maize inbred lines and evaluate the biochemical components that have an important role in physiological quality of seeds. The seeds of the inbred lines and hybrids were submitted to viability test, vigor by the accelerated aging and cold tolerance, and biochemical profiling (total protein content, soluble proteins, total phosphorus, phytate, inorganic phosphorus, starch and soluble sugars). The genetic divergence between the inbred lines found, prompt us to conclude that genetic gains may exist in association with physiological quality of maize hybrids. Seeds with higher inorganic phosphorus and soluble sugars presented superior physiological quality than seeds with lower levels of those compounds.

Promising Perspective

The tomato industry has been searching for new genotypes with improved fruit production, both in the field and industrially processed, together with high-quality performance under sustainable management conditions. This research was carried out in Southern Italy with the aim of assessing the effects of industrial processing on the yield and quality of four tomato hybrids grown according to organic farming methods and addressed at dicing. MAX 14111 and HMX 4228 showed the highest values of field and processing yield as well as reduced sugars and fructose. MAX 14111 had the highest values of total solids and soluble solids, titratable acidity, fiber, energetic value, polyphenols, and also rutin, though not significantly different from Impact. HMX 4228 performed best in terms of sugar ratio, color and naringenin. Concerning the diced products, the sensorial qualities of the four hybrids differed significantly. Total polyphenols, naringenin and rutin in the tomato fruits were higher in the processed than in the raw product. The appreciable fruit yield and quality resulting from both field and processing phase represent a promising perspective for identifying improved tomato genotypes addressed at dicing.

Yield And Quality

Brazil is the world's largest producer of sugarcane, the main raw material used for the production of alcohol and sugar. The crop to achieve good levels of productivity demands high amounts of nutrients, which are usually supplied by the use of mineral fertilizers. An alternative for efficient fertilization is through the use of organomineral fertilizers. Such fertilizers consist of the mixture of organic fertilizers of animal or vegetable origin, and mineral fertilizers that undergo industrial processing. The industrial advance associated with the population increase has generated a large amount of solid waste and wastewater. One way to reduce the effects of environmental pollution from the presence of these solid wastes is through their treatment, giving rise to a pasty material, known as sewage sludge. Sewage sludge presents the potential to be used in the mineral nutrition of plants, both as fertilizer and as a soil conditioner. Biostimulants are natural or synthetic substances that can be applied directly to plants to increase yield and quality of crops of economic interest. Thus, the present review aims to report the study on the use of organomineral fertilizers from sewage sludge and biostimulant in sugarcane cultivation.

Kernel Row Number

Sweet maize differs from maize of standard grain quality by many important traits that affect the ear appearance, and especially by traits controlling taste. The ear appearance trait encompasses the kernel row number, configuration, row pattern (direction and arrangement), seed set, kernel width and depth, ear shape and size. The quality of immature kernels is controlled by genes by which sweet maize differs from common maize. In order to obtain high-ranking and high-quality yields, it is necessary to provide the most suitable cropping practices for sweet maize hybrids developed at the Maize Research Institute, Zemun Polje. The adequate sowing density is one of more important elements of correct cropping practices. The objective of the present study was to determine the effect of four sowing densities in four ZP sweet maize hybrids of different FAO maturity groups on ear qualitative traits and yields obtained on chernozem type of soil in Zemun Polje. The observed traits of sweet maize (ear length, kernel row number, number of kernels per row, yield and shelling percentage) significantly varied over years. The higher sowing density was the higher yield of sweet maize was, hence the highest ear yield of 9.67 t ha-1 , on the average for all four hybrids, was recorded at the highest sowing density of 70,000 plants ha-1. The highest yield was detected in the hybrid ZP 424su. The highest shelling percentage (67.81%) was found in the hybrid ZP 521su at the sowing density of 60,000 plants ha-1. Generally, it can be stated that sweet maize hybrids of a shorter growing season (FAO 400) could be cultivated up to 70,000 plants ha-1, while those of a longer growing season (FAO 500) could be grown up to 60,000 plants ha-1. In such a way, the most favorable parameters of yields and the highest yields can be obtained.
