The present study aimed to investigate the selection of genotypes tolerant to drought are greatly important, especially considering the actual panorama of climate change, in which the temperature rises and the period of water restrictions may extend, greatly impacting the agriculture. In breeding programs, it is necessary to compare the performance of different genotypes when subjected to water stress to make possible to identify sources to improvement toward the drought tolerance and water use efficiency. This experiment aimed to evaluate the early growth of genotypes of physic nut (Jatropha curcas L.) cultivated with different levels of available water in the soil. The experiment followed a 5x4 factorial scheme, submitting five genotypes of physic nut (CNPAE 128, CNPAE 170, CNPAE 171, CNPAE 183 e CNPAE 198) to four levels of water availability in the soil (10%, 30%, 50% and 100%), in a completely randomized design, in order to evaluate their initial growth. Biometric variables and biomass production and allocation were measured. The results show that, to a certain degree, plants of physic nut are able to tolerate water deficit, keeping growth and biomass production in different levels of available water in the soil. It can be inferred that plants of physic nut are able to develop efficient strategies to tolerate these conditions, such as reduction of leaf area and preservation of stem juiciness. Plants of physic nut are able to tolerate drought without compromising the total production of biomass in the initial stages of development. It is possible to identify differences among genotypes of physic nut regarding the response to the drought MenosThe present study aimed to investigate the selection of genotypes tolerant to drought are greatly important, especially considering the actual panorama of climate change, in which the temperature rises and the period of water restrictions may extend, greatly impacting the agriculture.
