abstract = {The objective of this study was to evaluate citrus progenies reaction to drought stress and shoot emission capacity in order to identify those with potential for generating hybrids that can be used as rootstocks, mainly in the Coastal Tablelands of the Brazilian Northeast, where the rainfall distribution does not meet the water requirements for citrus production throughout the year. The Citrus Breeding Program of Embrapa Cassava and Fruits conducted controlled crossings having as female parents the ‘Rangpur Santa Cruz’ lime (RSCL) and the ‘Sunki of Florida’ mandarin (SFM), and as male parents, besides this mandarin, the ‘Indio’ (IDC) and ‘Riverside’ (RSC) citrandarins, ‘Thomasville’ citrangequat (THOM), ‘Swingle’ citrumelo (SWC), ‘Argentina’ citrange (AGC) and ‘Benecke’ trifoliate orange (BKTO). The hybrids generated were visually evaluated in the period from 2011 to 2014 for drought stress and water use capacity, on the basis, respectively, of leaf curling, evaluated at the end of periods of intense drought stress, and shoot emission, determined immediately after the occurrence of rains following those intense stress periods. The hybrids of RSCL were less sensitive to drought stress, and the SFM mandarin generated hybrids with good water use, due to their good shoot emission capacity in response to water deficit. This is an indication of the capability of this mandarin to produce hybrids with good rehydration ability.},

abstract = {ABSTRACT: Rootstocks influence certain characteristics of the scion, such as vigor, fruit yield and quality, and tolerance to biotic and abiotic factors. In conventional citrus breeding programs, hybridization is the main method used for obtaining rootstock varieties. Between Sept and Oct 2006, controlled pollinations were carried out resulting in nine progenies, totaling 461 hybrid seedlings. The female parents were the ‘Santa Cruz Rangpur’ lime (SCRL) and the ‘Sunki of Florida’ mandarin (SFM), while the male parents, in addition to this mandarin, were the ‘Indio’ and ‘Riverside’ citrandarins, the ‘Thomasville’ citrangequat (THOM), the ‘Swingle’ citrumelo, the ‘Argentina’ citrange (AGC) and the ‘Benecke’ trifoliate orange (BKTO). Fruit setting rates of these crosses were measured and the hybrids generated were planted in the field in 2008 and evaluated from 2010 to 2014, for the variables of plant mortality, visual vigor, plant height and trunk diameter. The descriptive statistics mean, variation range, coefficient of variation and Pearson skewness coefficient were calculated. Data were submitted to analysis of variance and the means of the treatments were grouped by the Scott-Knott test, both at 5 % significance. The progenies, having the ‘Sunki’ mandarin as the female parent, presented higher fruit setting rates and lower plant mortality rates than those obtained from the female parent ‘Rangpur’ lime, while zero plant mortality was observed in the SFM × BKTO cross. The crosses SCRL × SFM, SFM × BKTO, SFM × AGC and SFM × THOM have the potential to generate vigorous hybrids, resulting in rootstock varieties adapted to the landscape unit of Coastal Tableland.},
