  • Antioxidant variability of wheat genotypes under salinity stress in situ
    Genetika, 2020
    Co-Authors: Borislav Banjac, Miodrag Dimitrijevic, Sofija Petrovic, Velimir Mladenov, Dusana Banjac, Biljana Kiprovski
    Abstract:

    Crop cultivation under the open-field conditions depends on a variety of biotic and abiotic factors which cause plant stress and deterioration. Due to high soil salinity, some soils can be an unfavourable growing environment for most plants. As a low productivity soil type, Solonetz soils are a stressful growing environment, causing plant deterioration. Plants have developed a complex antioxidative defense system as a precaution against oxidative stress caused by high soil salinity. The trial was set up on a halomorphic soil type-Solonetz. The research included ten cultivars, one local population of hexaploid wheat (Triticum aestivum ssp. aestivum L.) and one cultivar of triticale (Triticosecale W.). The activity of enzymatic and non-enzymatic antioxidants in plant antioxidative defense system was detected during the trial, as well as lipid peroxidation. The analysis of biochemical markers was done in the flowering stage, and then in the milk maturity phase. Research results of the tested components revealed the highest stress tolerance exhibited by genotypes Banatka and Bankut 1205. Understanding the process of oxygen radical production by the plant tissue contributes to breeding wheat cultivars for better stress tolerance. Selection of genotypes better adapted to growing conditions in Solonetz soils could facilitate a more economically justifiable wheat production, and promote utilization of the lower-quality soil types in agriculture.

  • Stability of yield components of bread wheat grown on different soil types
    Selekcija i semenarstvo, 2015
    Co-Authors: Borislav Banjac, Sofija Petrović, Miodrag Dimitrijević, Velimir Mladenov
    Abstract:

    One of the main breeders tasks is improving characteristics of existing varieties and creating new genetic variability, which will achieve better economic effect. By observation of genotypes in different environmental conditions and by assessment of their interaction ideal genotypes for specific growing area will be chosen. The aim of this study is evaluation of genotype/environment interaction for plant height and grain weight per spike, grown Solonetz and chernozem. The experiment was set in two different agro-ecological locations, Kumane (Banat) on Solonetz soil and on Rimski Šančevi, chernozem. During two growing seasons 2013/2014 and 2014/2015 three genotypes of bread wheat: NSR-5, Pesma and Renesansa were examined. Based on an interaction between genotype and agro-ecological environment for plant height and grain weight per spike, presented trought AMMI1 biplot, it was noted that the genotypes differed more in multivariate part of the variation then in an additive effect

  • Genotype × environment interactions and phenotypic stability for wheat grown in stressful conditions
    Genetika, 2014
    Co-Authors: Borislav Banjac, Sofija Petrović, Miodrag Dimitrijević, Velimir Mladenov, Jan Bocanski
    Abstract:

    The objective of this study was to present the results of experiment conducted on 11 cultivars of wheat (Triticum aestivum L.) and 1 cultivar of triticale (Triticosecale W) on stressful conditions of halomorphic Solonetz in Kumane, Banat, Serbia. Across three growing seasons genotypic variability, monitoring of phenotypic variation and genotype by environment interaction (GEI) for number of grains per spike and yield was studied. The cultivar were grown in field trails of control treatment and treatments with measures repairs Solonetz using phosphogypsum in the amount of 25 t•ha-1 and 50 t•ha-1. GEI was tested using AMMI (Additive Main Effects and Multiplicative Interaction) model. The expression of tested traits were statistically significant and showed additive and non-additive sources of variation. The first source of variation, quantified IPCA1 axis explained most of the structure of GEI.

  • Wheat breeding in abiotic stress conditions of Solonetz
    Genetika, 2012
    Co-Authors: Miodrag Dimitrijević, Sofija Petrović, Borislav Banjac
    Abstract:

    The complex stress environment at locality Kumane (Banat) primarily is caused by alkaline soil of Solonetz type, but includes the other sources of wheat variability, water-logging and occasional extreme temperatures, as well. In order to obtain wheat varieties that could fulfill the requirement of enhanced tolerance to abiotic stress conditions of alkaline soil a set of wheat varieties was examined in parallel trials in Kumane (Solonetz), and at Rimski Sancevi on chernzem (black soil). The multiyear results helped to select usable wheat genetic material among the existing varietal genetic variability. That variability was used as parents in in situ established crosses. The results in segregating F2 offspring surpassed the average parental values for examined traits - plant height, grain number and grain weight per spike. Hence, selecting desirable genetic variability in novel variability through years could lead to wheat plant ideotype capable to bring forth a economically justified yield.

  • 1 The alkali soils of the middle Niger Valley Origins, formation and present evolution
    2015
    Co-Authors: Laurent Barbiero, Brigitte Van Vliet-lanoë
    Abstract:

    Republic, the regional development of irrigation along the river Niger is confronted with an large extension of alkali soils. The study of one of these areas, on the Liptako bedrock, reveals a concentric soil distribution: in a zone of brown soil with abrupt textural change and alkaline in depth (stagnic Solonetz), appears a ring of brown steppe soils (cambic Calcisol), and zones of alkali soils (Solonetz). These alkali soils are not saline but their soil solution is more concentrated than in brown steppe soils. The study of the abrupt contact between brown steppe soils and alkali soils shows morphological and geochemical changes, due to calcite and fluorite precipitation. The detailed study of this contact demonstrates a present transformation of alkali soils into brown steppe soils. Therefore, it appears that soil alkalization is no longer in process on the terraces of the river Niger. The formation of brown steppe soils and alkali soils may be explained by the existence of a former pond. This hypothesis is supported by aerial pictures and microscopic observations. It is also consistent with a recent study of the hydrology of sahelian ponds and with considerations on the chemical quality of the runoff. Key words: non-saline alkali soils/sodic soils, soil genesis, de-alkalization, Sahel, Niger

  • The alkali soils of the middle Niger Valley Origins, formation and present evolution
    Geoderma, 1998
    Co-Authors: Laurent Barbiero, Brigitte Van Vliet-lanoë
    Abstract:

    In Niger Republic, the regional development of irrigation along the river Niger is confronted with a large extent of alkali soils. For a sound management of the irrigated area, it appears necessary to understand the present evolution of these alkali soils. The study of one of these areas, located on the Liptako bedrock, reveals a concentric soil distribution: within a zone of brown soil with abrupt textural change and alkaline in depth (stagnic Solonetz), appears a ring of brown steppe soils (cambic Calcisol), around zones of alkali soils (Solonetz). These alkali soils are not saline but their soil solution is more concentrated than in brown steppe soils. The abrupt boundary between the brown steppe soils and the alkali soils is related with morphological and geochemical changes, resulting from calcite and fluorite precipitation in the soil solution. The detailed study of this contact demonstrates the current transformation of alkali soils into brown steppe soils. Therefore, it appears that soil alkalization is no longer in process on the terraces of the river Niger. The formation of brown steppe soils and alkali soils may be explained by the juxtaposition of two contrasted hydrological regimes in a former pond. This hypothesis is supported by aerial pictures and microscopic observations. It is also consistent with a recent study of the hydrology of Sahelian ponds and with considerations on the chemical quality of the runoff.

  • Variability of plant height and harvest index of various wheat genotypes cultivated on chernozem and Solonetz
    Genetika, 2006
    Co-Authors: Zoran Kapor, Sofija Petrović, Miodrag Dimitrijević
    Abstract:

    Solonetz is a type of halomorphic soil which is present on 80 000 ha in Vojvodina. Field experiments were conducted during 1999/2000 vegetation periods, involving eleven wheat genotypes cultivated on Solonetz, location Kumane, and on chernozem, location Rimski Sancevi. The variability of plant height and harvest index on different soil types was investigated, as well as the correlation between these two yield parameters. The goal of this research was to establish the significance of various genotypes and soil type effects on plant height and harvest index, as well as the reaction of genotypes regarding different amelioration rates on Solonetz.
