| The rice is large-scale cultivated in a wide range of edaphic and climatic conditions, compounding an alternative source for the increase in food production worldwide. The present study assessed the traits related to productivity, in rice genotypes under conditions of irrigation and water stress, in Gurupi municipality, Southern region from Tocantins state. We evaluated agronomic attributes (number of tillers and panicles, number of grains per panicle and productivity), besides the index of drought sensitivity. The selection of superior genotypes and traits that may serve for the differentiation among the genotypes in this stress condition is essential to create more tolerant materials. Among the most productive genotypes, we highlight the ‘Quebra Cacho’... |
