Study of the Behavior of Some Spring Barley Lines with Two Rows Created at A.R.D.S Turda Regarding Production Capacity and Quality

The spring barley is a variety of a superior quality for brewing compared with the feed barley due to several reasons. Research was conducted in the field of breeding of spring barley with two rows, within ARDS Turda, during 2013-2015. The trials were comparatively developed, and included 25 variants. The biological material was represented by four  autochthonous genotypes: Turdeana, Daciana Romaniţa (A.R.D.S. Turda), and Adina (A.R.D.S. Suceava). The spring barley lines created by the S.C.D.A. Turda, meet the requirements of the beer industry in terms of protein content, starch, M.M.B. and germination energy

The Heritability of Some Qualitative and Quantitative Traits at One Set of Spring Barley Genotypes

Work collections are subjected to a renewal process, therefore a regular evaluation is needed inorder to appreciate the genetic advance of the existing variability at collection level and further to identify valuable genotypes in terms of morphoproductive and qualitative traits (protein, starch). The barley intended for brewing must correspond to some qualitative parameters, of which proteins and starch content are of major importance. For this purpose, a study was conducted to assess the variability and heritability indicators corresponding to the two traits at 48 barley genotypes. The genotypes that were the subject of this study were sown in three experimental years 2013, 2014 and 2016. The mean values of 2013 year was 13.71 compared with only 10.77, and 11.27 in 2014 and 2016. The significant value of the heritability coefficient along with the genetic advantage of 0.81 indicates the success of selection work for this important chemical trait

Researches on Some Biological and Ecological Characteristics of Sweet Corn

Lately, genetic factor involvement in climate change response is of great importance. Addressing some issues regarding the behavior of agronomic characters of production in a set of hybrids may lead to recommendations on the choice of the most suitable hybrids for growing in Transylvanian Plateau. Thus, in 2016, we set up an experience in two locations of Cluj county, Turda and Viişoara, on the lower terrace of Arieş river. Biological material chosen for this study was represented by seven hybrids, of which six indigenous Prima, Estival, Estival M, Dulcin, Deliciul Verii (released by SCDA Turda), Delicios (INCDA Fundulea) and foreign hybrid Jubilee (produced by Syngenta). The earliest hybrids Prima and Estival, have the lowest average number of grains/row, with very significant differences compared to control (experience average). Estival, Estival M and Jubilee hybrids show the highest number of rows of grains/cobs, with very significant differences over the average

RESEARCHES ON SOME BIOLOGICAL AND ECOLOGICAL CHARACTERISTICS OF SWEET CORN

Sweet corn is a stenotermal plant that endures limited temperature variations requiring also adequate levels of humidity. Many farmers assume some risks in this direction, but they can sometimes compromise a significant percentage of culture. So many times to reach the phrase "first on market gets high-prices" is to resort to sowing too early and not to purchase early hybrids. Objective of this paper was to elucidate some aspects regarding behavior of certain hybrids of sweet corn with regard to certain attributes of production under Transylvanian Plateau conditions. Also, for growing surfaces cultivated with sweet corn, the biological material was also analyzed in terms of adaptability to mechanized harvesting. Delicios hybrid is distinguished by the lowest values of the coefficient of variation in the two years, indicating a good uniformity of cob insertion and the possibility of mechanized harvesting

THEE BEHAVIOUR OF SOME SPRING BARLEY GENOTYPES (HORDEUM VULGARE) UNDER CONDITIONS OF IMPOSED DROUGHT

The climatic data of the last years presents a significant growth of temperatures even in the cultivation areas of two-rowed spring barley. These intervals of drought appear especially in the period of grain formation and filling, bearing a negative impact on production, both from the qualitative and quantitative points of view. Thus, in order to simulate the drought phenomenon, the method proposed by Blum (1983), cited by Elena Petcu and colab., (2014), was used. This method consists in treating the plants with desiccants (e.g. Sodium chlorate) in a 2% concentration, 14 days after the anthesis. Thus, the cultivars that manage to translocate a greater quantity of reserve carbohydrates from the vegetative organs towards the grains, present a better stability of grain weight under conditions of hydric stress
