“…These cultivars have been selected because adapted to completely different environmental conditions (temperature, rainfall, soil conditions) where high fitness and productivity parameters may be linked to specific phenotypic traits (Figure 2). L. corniculatus Leo cv has been already exploited in mixed pastures for testing hydrocarbon degradation in contaminated soil after inoculation with bacteria degrading strains [27,28] and for assessing herbicide resistance and freezing tolerance through in vitro studies [29,30]. Furthermore, natural and transgenic lines polymorphic for condensed tannins quantity in vegetative tissues have been selected and characterized in the Leo cv [31,32,33,34].…”

The establishment of legumes crops with phenotypic traits that favour their persistence and competitiveness in mixed swards is a pressing task in sustainable agriculture. However, to fully exploit the potential benefits of introducing pasture-based grass-legume systems, an increased scientific knowledge of legume agronomy for screening of favourable traits is needed. We exploited a short-cut phenotypic screening as a preliminary step to characterize the growth capacity of three different Lotus corniculatus cvs cultivated in different nutritional conditions as well as the evaluation of their nodulation capacities. This experimental scheme, developed for legume species amenable to grow on agar plates conditions, may represent a very preliminary step to achieve phenotypic discrimination on different cultivars.

“…In vitro selection was quickly embraced by plant pathologists and plant breeders alike to select for resistance to plant pathogens producing toxins involved in pathogenesis (for reviews see Buiatti and Ingram 1991;Svabova and Lebeda 2005). There has also been an interest over the years in selecting for salt tolerance (e.g., Karadimova and Djambova 1993;Winicov 1996;Zhang et al 2001;Dziadczyk et al 2003;Queiros et al 2007;Hamrouni et al 2008;He et al 2009) and herbicide resistance (e.g., Kinoshita and Mori 1991;Pofelis et al 1992;Baillie et al 1993;Escorial et al 1996;Taregyan et al 2001;Yu et al 2004;Gurel et al 2008) using such culture systems.…”

Plant breeding has had a tremendous influence on crop improvement. However, due to dwindling germplasm resources, identification of variability for incorporation into new cultivars is becoming more difficult. Therefore, there has been recourse to alternative approaches including mutagenesis, tissue culture and genetic transformation to aid breeding programs. Furthermore, with the vast repertoire of genome-wide data from different expression profiling techniques such as microarrays, more subtle understanding of gene expression is being obtained and is further helping plant breeders to entertain a different selection approach based on expression quantitative traits to maximize combinations of genes capable of conferring high performance. In this chapter, we review some of the aspects of plant breeding and the influence functional genomics has on breeding programs. Some of the challenges to functional genomics and breeding come from establishment of high-throughput transformation systems to assess gene function, which is limiting functional characterization of numerous genes in their respective crops. Therefore, this chapter also focuses on the need to gain better understanding of the development of gene transfer systems for crop plants to make use of the array of available gene information data.

“…The application of herbicides with active substances from the same group results in a change in species composition of weeds [LABRADA, 2000;POFELIS andGRANT, 2001, BUTNARIU et al, 2006] . The weed plants, which are sensitive to applied herbicides, are devastated, while the resistant ones are spreading and increasing [NAGI, 1995, CAUNII et al, 2015, BUTNARIU, 2012 .…”

Abstract. In the experimental field of RIMSA-Troyan was studied the herbicidal effect of Aramo 45 (45 g/L Tepraloxydim) at doses of 1 and 2 L/ha, and Dual Gold 960 EC (960g/L smetolachlor)-2 and 3 L/ha, during the period of 2013-2015 on light grey pseudopodzolic soil, over the weed infestation level and productivity of bird's-foot-trefoil. It was found that both herbicides in both doses showed good selectivity in relation to bird's-foot trefoil. Most pronounced was the effect by the applied herbicides regarding the degree of weed infestation in the year of sowing, as the treatment by Aramo 45 at a dose of 2 L/ha and Dual Gold 960 EC at a dose of 2 L/ha provided a degree of weed infestation of 6.68 and 16.11 %. The vegetation treatment of a grassland of bird'sfoot-trefoil by Aramo 45 herbicide at a dose of 1 and 2 L/ha led to an increase in dry matter yield with 21.85 and 18.21 %, and with Dual Gold 960 EC EK it was 24.28 and 30.29 %. Dual Gold 960 EC showed a greater effect from both tested herbicides over the dry matter yield, applied at a dose of 3 l/ha at a phase of 2-4 leaf stage of bird's-foot trefoil. That herbicide could be recommended for the application in the practice in creating weed-free crops of bird's-foot-trefoil for forage production.
