Variability and genetic structure of yellow passion fruit (Passiflora edulis f. flavicarpa Degener) in Colombia using microsatellite DNA markers

open access: yesAgronomía Colombiana, 2017
Colombia is one of the leading producers of yellow passion fruit but the genetic studies based on molecular markers from commercial plantations have not been considered to select interesting market material.

Genetic Structure of Cultivated Varieties of Radicchio (Cichorium intybus L.): A Comparison between F1 Hybrids and Synthetics

open access: yesPlants, 2019
Cichorium intybus L., well known in Italy with the common name “Radicchio”, is an important leafy vegetable that is prevalently reproduced by allogamy due to very efficient barriers of self-incompatibility.

Variation of reproduction in some species of the tribe Aveneae (Poaceae)

open access: yes, 2015
Patterns of reproduction were studied in a series of inter- and intraspecific units in the genus Avena. The range of variation of the mating system is from autogamy to allogamy.

Hidden genetic variance and residual allogamy contribute to increase the adaptive potential of selfing populations

open access: yes, 2019
Abstract Standing genetic variation is considered a major contributor to the adaptive potential of species. The low heritable genetic variation observed in self-fertilising populations has led to the hypothesis that species with this mating system would be less likely to adapt.

Flower and fruit structure of the endangered species Petagnaea gussonei (Sprengel) Rauschert (Saniculoideae, Apiaceae) and implications for its reproductive biology [PDF]

open access: yes, 2015
Petagnaea gussonei (Apiaceae) is an endangered species endemic to the Nebrodi mountains (north-eastern Sicily). Although an increasing number of studies have been performed on this species, its reproductive biology remains poorly understood.

RICE (Oryza sativa L.) ALLOGAMY AND RELATIONSHIP WITH AGRONOMIC TRAITS

open access: yes, 2007
A produção de sementes híbridas de arroz, utilizando a técnica chinesa, requer uma grande quantidade de mão-de-obra e é cara. Alternativas para aumentar a taxa de polinização cruzada podem ajudar a reduzir tal custo. A Embrapa Arroz e Feijão desenvolve um projeto de produção de híbridos através da transferência de caracteres alogâmicos (comprimento de ...

INFLUÊNCIA DA POLINIZAÇÃO E DA MORFOLOGIA FLORAL NA FRUTIFICAÇÃO DE VARIEDADES DE LARANJA-DOCE INFLUENCE OF POLLINATION AND FLORAL MORPHOLOGY ON FRUIT SETTING IN SWEET ORANGE VARIETIES

open access: yesScientia Agricola, 1999
A espécie de laranjas doces (Citrus sinensis [L.] osbeck) é citada como sendo autógama. No entanto a alogamia tem sido demonstrada pelo aumento da produção de frutos com o uso de polinizadores eficientes, assim como pela existência de bons ...

Additional file 8 of Can ploidy changes propel the evolution of allogamy in a selfing species complex?

open access: yes
Additional file 8. Mathematical notation corresponding to each model. Models were tested with lme4 package in R for the effect of the independent variables Treatment and Ploidy and their interaction on the dependent variables Seedset, Fertility and Fertilization success.

BREEDING SYSTEM AND POPULATION STRUCTURE OF ARMERIA MARITIMA (MILL.) WILLD. ON A ZINC‐LEAD MINE

open access: yes, 1976
Using marker genes the breeding system (mating type gene) and the structure (hairy stalk gene) of a zinc–lead mine population of Armeria maritima, an insect‐pollinated plant, was studied in situ.
