ABSTRACT Habanero pepper is important in the international market and is becoming popular in the national market; however, few cultivars adapted and resistant to devastating diseases caused by the soilborne pathogens Ralstonia pseudosolanacearum (RP) and Phytophthora capsici (PC) are available in Brazil. The aim of this study was to evaluate the reaction of Habanero-type advanced inbred lines, developed by Embrapa Hortaliças breeding program, to RP and PC. Although not required for the process of protection, registration and release of new cultivars, this information is important. CNPH 15.737; CNPH 15.740; CNPH 15.744; CNPH 15.745; CNPH 15.749 and CNPH 15.750 were inoculated with three RP and one PC isolates. Plants showing wilted leaves (RP) and stem...

Método de obtenção de híbridos interespecíficos entre Lycopersicon esculentum e L. peruvianum
Provedor de dados: 86
Autores: Ribeiro,Cláudia Silva da Costa; Giordano,Leonardo de Britto.
A transferência de genes da espécie silvestre Lycopersicon peruvianum para a espécie L. esculentum por processo convencional de hibridação é limitada por incompatibilidade. O objetivo deste trabalho foi desenvolver um método de obtenção de híbridos entre essas duas espécies, mediante a técnica de cultura de óvulos, tendo em vista o interesse em transferir genes presentes em acessos de L. peruvianum que conferem resistência a Septoria lycopersici. Foram utilizados os acessos CNPH 946, CNPH 947 e CNPH 948 de L. peruvianum e as cultivares Floradade e Ipa-5 de L. esculentum. Sementes híbridas de frutos com 25-68 dias após a polinização foram colocadas para germinar inicialmente em meio de cultura Murashige &amp;amp; Skoog (MS), e posteriormente em meio HLH. As...

ABSTRACT:  The objective of this study was to evaluate the plant and fruit characteristics in advanced lines of Jalapeño pepper for mechanical harvesting. Thus, two experiments were carried out in the field. Experiment I (2015) was conducted as a randomized block design (three replications and eight plants per plot) and Experiment II (2016) in a completely randomized design (five replications and ten plants per plot). In 2015, lines CNPH 30,112, CNPH 30,118, CNPH 30,147, CNPH 30,159, CNPH 30,183, and CNPH 30,245 were evaluated, together with the control ‘BRS Sarakura’. Significant differences were detected for fruit and plant characteristics (P&lt;0.05). Lines CNPH 30,118, CNPH 30,147, CNPH 30,159, and CNPH 30,245 were selected based on plant height and...
