Cultivated rice evolved from wild rices found growing along river estuaries. As a taste for cereal developed, cultivation began and migration of the early cultivators accelerated the evolution of cultivated forms adapted to different environments. Today most rice is cultivated under controlled irrigation. In several developing countries it is also grown in a variety of difficult environments where drought, soil fertility, insects, diseases, and mineral toxicity are important constraints. Most international research efforts have been concentrated on irrigated rice. But recently, more attention began to be paid to problems in the more difficult environments. Here we report some aspects of the Brazilian experience on upland rice, which indicates that technology can increase yields and reduce instability, and that under difficult environments, upland rice can be a stable and profitable source of food. Brazil produces about 9 million tonnes of rice yearly; 70% from upland and the rest from irrigated land. Total cultivated area varies from 5 to 6 million hectares. |

Water resources used for irrigation should be managed using technologies that improve water use efficiency, mainly in semiarid regions. Using drought-tolerant rootstocks is a strategy to handle this challenge. The objective of this study was to select suitable grapevine rootstocks for cultivation in semiarid regions based on their biomass, biochemical, and gas exchange attributes. The experiment was conducted at the Bebedouro Experimental Field of the Brazilian Agricultural Research Corporation (EMBRAPA Semiarid), in Petrolina, PE, Brazil. Rootstocks from grapevine plants of the cultivars Paulsen 1103, SO4, IAC 313, IAC 572, IAC 766, Ramsey, and 101-14 MgT were subjected to three irrigation water depths (100%, 50%, and 20% ET0). A randomized block experimental design with four replications was used, in a split-plot arrangement consisting of irrigation water depths in the plots and rootstocks in the subplots. Biochemical, biomass, and gas exchange attributes were assessed for selecting the best rootstocks regarding tolerance to drought using multivariate principal component analysis (PCA) and analysis of variance. The rootstocks IAC 313 and IAC 766 presented the highest root proline synthesis; IAC 766 presented better result for leaf sucrose synthesis; and Paulsen 1103 presented the highest leaf proline synthesis and carotenoid contents, as well as total chlorophyll-to-carotenoid ratio. IAC 313, IAC 766, and Paulsen 1103 presented better performance regarding the studied characteristics and, therefore, are suitable for growing grapevine crops in the Lower Middle São Francisco Valley, mainly under water deficit conditions.
