Breaking-bud pollination: a new pollination process in partially opened flowers by small bees

Journal of Plant Research, 2015
Plant-pollinator interactions have usually been researched in flowers that have fully opened. However, some pollinators can visit flowers before full opening and contribute to fruit and seed sets. In this paper, we researched the pollination biology of flowers just starting to open in four field experiments.

Heritability of some characters of rye under open pollination

Theoretical and Applied Genetics, 1972
Present investigations cover the correlation between four characters of maternal plants of rye and the corresponding characters in their offspring. Tabulated results pertain to four two-year periods for the Exp. Sta. Choryń and two such periods for the Exp. Sta. Laski, involving several plant material groups derived from various crosses with Dańkowskie

Effect of insect pollinator on inbreeding versus outbreeding in open pollinated strawberry seeds

Scientia Horticulturae, 2017
Abstract In Japan, honey bees, bumble bees, and flies are used in strawberry production to produce normally shaped fruits. These insects may determine the inbreeding or outbreeding of strawberry flowers. Whole-genome DNA of the strawberry cultivar ‘Shizutakara’ showed no amplification of DNA fragments when PCR was performed with a F3H CAPS DNA marker.

The Development of Self‐Pollinated Inbred Lines of Meadowfoam by Direct Selection in Open‐Pollinated Populations

Crop Science, 1997
Limnanthes alba Benth. (meadowfoam) is an allogamous insectpollinated oilseed crop. Poor pollination and pollinator costs have purportedly limited the commercial production of this crop. Production costs can be reduced and seed yields might be increased by using self‐pollinated cultivars.

Theory and application of open-pollination and polycross in forage grass breeding

Theoretical and Applied Genetics, 1990
Progeny testing and selection of forage grasses by means of growing half-sib (HS) families from openpollination and polycross have been considered from theoretical and practical points of view. Special attention has been paid to the genetic variation within half-sib families, which is expected to be large as compared to the genetic variation between ...

Population Improvement and Development of Open-Pollinated Varieties

2017
Population improvement is usually done by recurrent selection, a procedure that generally involves three basic stages of field work: development of progenies from the population being improved, evaluation of the progenies in field trials and selection of a certain percentage of the progenies based on their top performance, and recombination of the ...

CHARACTERIZATION OF ARTICHOKE OPEN POLLINATED AND HYBRID CULTIVARS BY PROTEIN ELECTROPHORESIS

Acta Horticulturae, 2005
Abstract: Little research-based information is available on artichoke (Cynara cardunculus L. subsp. scolymus Hayek) genetic variability achieved by biochemical and molecular markers. Studies on artichoke cultivars characterization by achene proteins analysis are unknown. The pattern of achene proteins, assessed by sodium dodecyl sulphate polyacrylamide

A comparison of genetic information from open-pollinated and control-pollinated progeny tests in two eucalypt species

Theoretical and Applied Genetics, 1996
Genetic-parameter estimates and parental breeding-value predictions were compared from open-pollinated and control-pollinated progeny populations of Eucalyptus globulus and two populations of E. nitens. For E. globulus there were two types of open-pollinated populations (native stand open-pollinated and seed orchard open-pollinated) and two types of ...

The Composition of an Open Pollinated Segregating Cotton Population

The American Naturalist, 1956
(1) By analysing the open pollinated progeny from a segregating population of cotton whose initial composition in respect of four marker genes is known, it has been possible to estimate separately the relative frequency of three types of pollination: (a) The proportion of apparent out-pollination (AOP), i.e. "foreign" pollination. (b) The proportion of

Diallel study of open-pollinated maize varieties in Trinidad

Euphytica, 1996
In Trinidad, maize (Zea mays L.) is primarily harvested in the immature stage as green ears for human consumption. The purchase of popular imported hybrid seed has become a substantial component of the economic inputs of maize production. The objectives of this study were to investigate combining abilities and heterotic patterns among available open ...
