Weed management in sugarcane fields must be performed rationally, taking into consideration the competitive ability of cultivars and weeds, to allow for reductions in control costs and herbicide use. In this study, an evaluation was made of the interference of populations of Brachiaria brizantha in sugarcane cultivars, with the objective of estimating the economic threshold level of B. brizantha in competition with the cultivars RB72454, RB867515 and SP801816. For this purpose, an experiment was conducted under field conditions, where the cultivars coexisted with different weed densities. Considering the average values of the variables used for calculations, an economic threshold level was achieved with a population of 0.33, 0.46 and 0.66 plants m-2 of B. brizantha for cultivars RB867515, RB72454 and SP801816, respectively. |

The increasing world population and consumer requirements are driving forces for rice (Oryza sativa L.) breeding programs worldwide. The development of novel cultivars is challenged by the necessity of combining high yield and superior quality traits, in a timely manner. Precision breeding strategies, such as genetic engineering and genome editing, are important tools to accelerate and improve conventional breeding. However, successful gene delivery is dependent on several biological factors underlying plant regeneration and trait expression. In this chapter, we present and discuss the available systems for gene delivery, used in conventional transformation and genome editing of rice, and the regeneration pathways employed in the production of whole plants expressing the novel phenotypes associated to grain quality. The interaction between the gene delivery system and its biological target in recovering transformed and/or edited plants is also discussed. |
