High Quality Seed

Seed production of field crops plays a key role in ensuring food security of the country and is a continuation of the selection process, a necessary link for the development and maintenance of the variety. In seed production, the main object is a variety that is genetically close to each other a certain group of plants, homogeneous in morphological and biological properties. The finish of high-quality seed production is seeds with good varietal and sowing qualities. The main condition for effective production of field crops is a well-established seed production system, which is a set of functionally interconnected structures engaged in the production of elite and reproductive seeds. Seed production of field crops solves two main tasks: variety exchange and variety renewal. When a variety is changed, one zoned variety is replaced by another with more valuable economic characteristics. During variety renewal, varietal seeds in farms are replaced with seeds of the same varieties, but of higher reproductions. Usually, seeds for cereals and legumes are updated every 3-4 years, for millet - every 2 years, for sunflower - annually. The main goal of seed production of field crops is to maintain a set of characteristics of the variety, its most valuable qualities and economic indicators.

One of the leading grain crops in Russia is spring wheat. This is a strategic food crop of our country; it is also an important component in the structure of forage crops for monogastric animals, such as pigs and poultry. The purpose of the research was to evaluate spring soft wheat varieties of different maturity groups in order to identify genotypes as the starting material for obtaining varieties adapted to the cultivation zones, and to determine the areas optimal for the production of grain for seed purposes with high quality indicators. Field studies have been carried out in three ecologically different zones: the Priobskaya zone, the Prialtaiskaya zone, and the Prisalairskaya zone. Under the conditions of the Altai Territory, genetic sources of spring soft wheat have been identifi ed for different soil and climatic parameters of the study zones, the use of which will allow obtaining high-yielding varieties with high quality grain for specific cultivation conditions. The variability of the indicators of the characteristics of varieties in three ecologically different zones has been determined. The indicators of adaptability and stability of spring soft wheat varieties in different zones of cultivation have been determined. The optimal zones for conducting breeding work and seed production of varieties have been identifi ed. New scientific data on the quality parameters of seed grain in various agro-climatic zones of the Altai Territory have been obtained. The share of the contribution of the factors “variety”, “year”, “environment” to the variability of grain quality characteristics has been established. The economic efficiency of cultivating varieties of spring soft wheat for the production of high-quality seed grain has been determined.

Vegetable seed has been produced in New Zealand for over a century. In the late 1900s the potential for global trade was realised and Canterbury has become the major area of vegetable seed production in New Zealand. The main species involved are onion, baby leaf vegetables, sweet corn and brassica. Squash, capsicum, tomato, lettuce and telegraph cucumber are also important. This paper outlines the development of the vegetable seed industry in New Zealand and suggests that future requirements to meet increasing demand for high quality seed will be irrigation and mechanisation.

erusalem artichoke (Helianthus tuberosum L.) is a promising bioenergy multi-purpose crop. The Jerusalem artichoke is a valuable culture that is a source of inulin, fructose and pectin. Green mass of the Jerusalem artichoke has a high content of complex carbohydrate (fructose, glucose, sucrose, etc.) in the dry weight of the plant contain up to 17% protein with a balanced amino acid composition. Biotechnological methods are firmly established in plant growing practice and are widely used for rapid multiplication and obtaining healthy planting material of many economically important crops. The technology of micro clonal propagation “in vitro” has great importance for the development of seed production of Jerusalem artichoke and obtain sufficient quantity of high quality planting material. Formed innovative scheme of sequential technological process of seed production of Jerusalem artichoke includes the production of original seed material “in vitro” Jerusalem artichoke, mass reproduction by aero hydroponic installations, and the rationale based on research of the technology of growing high-quality seed of Jerusalem artichoke. It was found that at cultivation of minitubers of micro plants in aero hydroponic installation compared to farming by traditional technology, the cost of one minituber decreased by 9.58 RUB.

The present investigation aimed to evaluate the effect of Chitosan-Indole Butyric Acid (IBA) in the seed of Salicornia bigelovii under field conditions in Sonora, Mexico. During two vegetative cycles (2018/2019–2019/2020), cuttings of S. bigelovii were treated with 100 and 50% Chitosan from shrimp exoskeletons and indole butyric acid at 0.937 and 1.25 g·kg−1 and placed in basins under conditions of the Sonora desert, Mexico. Variables were measured: seed production, physicochemical analysis and lipid profile of the seed. The results affected significant increases (p < 0.05) in the evaluated variables, highlighting the treatment based on Chitosan 100%—IBA 0.937 g·kg−1. The results based on chitosan and IBA in cuttings, are a biostimulant in the morpho-physiology, yield production, and lipid content of S. bigelovii. Large-scale studies as a production system should be considered in further studies.

Pollinator Populations

The seed production of many field crops, and in particular of legumes, depends to a large degree upon the number of pollinating insects present in the field during the blooming period. A study of the various factors affecting seed production requires, among other things, a knowledge of the population of pollinating insects present, and a ready means of comparing pollinator populations from one field to another. To obtain this information some means must be employed to count and classify the pollinating insects in the field.

Abstract In breeding programmes, the genetic selection process is based on the prediction of animal breeding values, and its results may vary according to the employed selection method. The current study developed an economic selection index for animals of the Angus breed; performed cluster analyses using the breeding values in order to evaluate the genetic profile of the animals candidates to selection, and compared the obtained results between the economic selection index and the cluster analyses. The evaluated traits included weaning weight, 18-month weight, scrotal circumference, fat thickness and ribeye area. Economic values were obtained using bioeconomic modelling, simulating a complete cycle production system of beef cattle breeds in Brazil, and the selection objective were the weaning rate and slaughter weight. The chosen selection index was composed of all of the traits used as selection criteria for the simulated production system. During the cluster analyses, the population was divided into two to four groups, in which the groupings containing potential animals were assessed. The animals of the grouping which was used for comparison with the selection index were identified, and most of the bulls that were included in the index were among the best in the analysed group. These results suggest that the cluster analyses can be used as a tool for the selection of animals to be used as parents for future generations.

High Quality Seed

The production of high-quality seed is the basis for a durable a profitable agriculture. After production, seed is processed, conditioned, stored, shipped and germinated. For quality assurance, seed quality has to be controlled at all steps of the production chain. Seed functioning is accompanied by programmed transitions from cell proliferation to quiescence upon maturation and from quiescence to reinitiation of cellular metabolism upon imbibition. Despite the obvious importance of these control mechanisms, very little information is available at the molecular level concerning those elements that regulate seed germination. In the present study, the induction of cell cycle activity and the regulation of ß-tubulin expression is related to the water content and other physical properties of the seed.
