Eight upland cotton (Gossypium hirsutum L.) germplasm lines, GA qFL25-A1 (Reg.no. GP-1063, PI 690458), GA qFL25-A2 (Reg. no. GP-1064, PI 690459), GA qFL25-P1 (Reg. no. GP-1066, PI 690461), GA qFL25-P2 (Reg. no. GP-1065, PI 690460), GA qFL25-D1 (Reg. no. GP-1070, PI 690465), GA qFL25-D2 (Reg. no. GP-1069, PI 690464), GA qFL25-G1 (Reg. no. GP-1068, PI 690463), and GA qFL25-G2 (Reg. no. GP-1067, PI 690462), were developed by the Molecular Cotton Breeding Laboratory, Department of Crop and Soil Sciences, at the University of Georgia in Tifton, GA. These eight germplasm lines resulted from crossing 'Sealand 883' (SL883), a G. hirsutum line with significant introgression from G. barbadense L., with four diverse G. hirsutum parents, 'Acala SJ-4', 'Paymaster HS 26', 'Deltapine 50', andGA 2004089, an unreleased breeding line. Previous work identified qFL-Chr.25, a quantitative trait locus (QTL) inherited from G. barbadense with significant effect on fiber upper-half mean length (FL) carried by SL883. Bulked sister lines were selected with the aid of marker-assisted selection from several F3:5 segregating families from each of these four cross combinations to quantify the effect of the allele in sister lines with and without the QTL. The presence of the SL883 allele for qFL-Chr.25 resulted in FL increases of 0.6 mm (1.9%) to 3.5 mm (11.7%) compared with the corresponding sister lines without the QTL. These eight lines should be useful for marker-assisted improvement of fiber length |

Plants can be attacked by a wide variety of herbivores. Thus, developing protective mechanisms for resistance against these agents is an advantage for survival and reproduction. Over the course of evolution, many resistance mechanisms against herbivory have been developed by the plants. Induced direct and indirect resistance mechanisms can manifest in plants after herbivore attack. The two-spotted spider mite Tetranychus urticae is not a pest of maize crops (Zea mays), despite being reported infesting plants that may have resistances against this herbivore. We tested the hypothesis that maize plants would be able to induce direct resistance against T. urticae after, evaluating the effect of T. urticae infestation in maize plants on the development and reproduction of conspecifics. We tested induced direct resistance performing infestation and measuring biological parameters upon a second infestation. Maize plants, 40 days after sowing, were divided into two groups: 30 not infested by T. urticae (clean plants clean) and, 30 infested by the spider mite. Infestation of maize plants by T. urticae reduced the conspecific female adult survival. However, no change in the survival of immature or reproduction was observed. These results suggest the induction of induced direct resistances in maize by T. urticae. This is first report of direct resistance induction in Z. mays by the two-spotted spider mite T. urticae. |
