Produção e beneficiamento de sementes de arroz híbrido em Jaguaruana - CE

Abstract

Rice (Oryza sativa L.) is one of the most cultivated species and consumed in the world, standing out as the second most consumed cereal and daily food component of half the world's population. In Brazil, rice is grown in two ecosystems: the flood plains and highlands. The first genetic studies of rice were carried out in Indonesia, and in Brazil at the Instituto Agronômico de Campinas (IAC), which only in the 60's research began in the Northeast. Rice is an autogamous plants, which require the use of effective male sterility system to develop and produce F1 hybrids on a commercial scale resulting from crossing two genetically different parent through the three line system (A, B, and R) or male sterile system (MSS). Because of the importance of the production of hybrids and the discovery of new technologies, the improvement program of the BASF (Badische Anilin und Soda-Fabrik) aims at developing and providing biotechnology that add yield in hybrid seed production (F1) rice genetically modified, Indica subspecies (Hsien). The internship was carried out at BASF S. A. with plant biotechnology in the operating units located in Ceará - Jaguaruana and Limoeiro do Norte between the months January to June of 2015, which were developed trials with rice cultivation and production of hybrid seeds of rice, multiplication of transgenic seeds and income trials. The activities performed in BASF S. A. units in the state of Ceará were: monitoring areas (project biosafety); planting experimental plots with specified varieties; search of suitable experimental areas and maintenance of competition tests; demarcating the experimental area according to the protocol; harvest the plots and entering data for analysis; post-harvest assessments; aid in the storage unit and support activities to visitors at rehearsals. From the field experience on the developed and implemented activities proposed by the company, it was possible to acquire a large field of knowledge on the activities and all stages of production of hybrid seeds in rice.
