Abstract(s)
O presente estudo tem como objetivo contribuir para a seleção e multiplicação de
acessos precoces de coentro (Coriandrum sativum L.) do Alentejo. Foi efetuada a revisão
bibliográfica de trabalhos relacionados com o tema em estudo na ESBE/IPP, tendo-se
identificado 3 acessos de coentro mais precoces em cada trabalho/projeto. O material
vegetal utilizado no presente estudo, foi proveniente de 5 acessos de coentro, recolhidos
em diferentes locais do Alentejo no âmbito dos projetos Agro 34 (Cs6, Cs12; Cs20,
semente de 2014)) e PRODER 18660 (Cs13, Cs16, semente de 2021). Também foram
considerados para multiplicação os 3 acessos mais precoces da caracterização efetuada
no âmbito do projeto PDR2020 784-042741, cedidos pelo Banco Português de
Germoplasma Vegetal (BPGV). A sementeira foi efetuada com os mericarpos separados,
utilizando-se um espaçamento de 10cm na linha para as sementes de 2014 e do BPGV e
20 cm para as sementes de 2021 e 40 cm de entrelinha. No total foram semeados 77
genótipos dos 5 acessos em seleção. Os descritores de seleção (por planta)
considerados foram: no de plantas (emergência, final da seleção), densidade de
ramificação (0-9), vigor da planta (0-9), pigmentação antociânica do caule (1-3), data
início da floração, data maturação (colheita), altura da planta (cm), peso de frutos (g),
peso da umbela principal (g), tamanho do fruto (1-3). Os acessos onde houve uma maior
seleção (%) foram o Cs 16 e o Cs 13. Foram selecionadas 123 plantas no total (43 de
Cs13, 25 de Cs16, 30 de Cs12, 10 de Cs6, 15 de Cs20) para continuação dos trabalhos
de seleção futuros. Dos genótipos avaliados, as plantas mais precoces (início de floração)
foram identificadas no acesso CS 12. As plantas com maior vigor e densidade de
ramificações foram identificadas no acesso Cs 16, sendo também o acesso com maior
produção de frutos.
The present study aims to contribute to the selection and multiplication of early flowering coriander (Coriandrum sativum L.) accessions from the Alentejo region. A literature review was carried out on studies related to the topic at ESBE/IPP, identifying the three earliest coriander accessions in each study/project. The plant material used in this study came from five coriander accessions collected in different locations across the Alentejo, as part of the Agro 34 projects (Cs6, Cs12, Cs20; seed from 2014) and PRODER 18660 (Cs13, Cs16; seed from 2021). Also considered for multiplication were the three earliest accessions from the characterization carried out under the PDR2020 784-042741 project, provided by the Portuguese Plant Germplasm Bank (BPGV). Sowing was carried out using separated mericarps, with a spacing of 10 cm along the row for the 2014 and BPGV seeds, and 20 cm for the 2021 seeds, with 40 cm between rows. In total, 77 genotypes from the five accessions under selection were sown. The selection descriptors (per plant) considered were: number of plants (emergence, end of selection), branching density (0–9), plant vigor (0–9), stem anthocyanin pigmentation (1–3), flowering date, maturity date (harvest), plant height (cm), fruit weight (g), main umbel weight (g), fruit size (1–3). The accessions with the highest selection percentage (%) were Cs16 and Cs13. A total of 123 plants were selected (43 from Cs13, 25 from Cs16, 30 from Cs12, 10 from Cs6, 15 from Cs20) for future plant breeding work. Among the evaluated genotypes, the earliest flowering plants were identified in accession Cs12. The plants with the highest vigor and branching density were identified in accession Cs16, which also had the highest fruit yield.
