Background: Adoption of the hybrid rice varieties by farmers is often impaired by the high price of hybrid seed, due to low yields in hybrid seed production fields. Female outcrossing ability (FOA) and female hybrid seed production ability (FHSPA), d

Publikováno v: Theoretical and Applied Genetics

A sound understanding of crop history can provide the basis for deriving novel genetic information through admixture mapping. We confirmed this, by using characterization data from an international collection of cocoa, collected 25 years ago, and fro

Yield stability in Coffea canephora from diallel mating designs monitored for 14 years

Autor: Avner Bar-Hen, Pierre Bouharmont, Christian Cilas

Publikováno v: Heredity

The genetic parameters of several agronomic traits were estimated in #Coffea canephora# in a triangular diallel with six parents and in a partial diallel with 18 parents. The yield data came from harvests obtained over 14 years divided into an initia

Genetic mapping of sugarcane resistance to smut through bi-parental segregation and associations among modern cultivars

Autor: Raboin, Louis-Marie, Nibouche, Samuel, Pauquet, Jérôme, Telismart, Hugues, Dintinger, Jacques, Hoarau, J.H., Costet, Laurent, D'Hont, Angélique

Publikováno v: VIIIth ISSCT Pathology Workshop Petit-Bourg, Guadeloupe (FWI), 23-27 January 2006, programme and abstracts

Breeding for smut resistance is efficient because this trait is fairly heritable but it requires complicated screenings. Moreover, the genetic control of smut resistance is still unknown. With the objective to identify the mendelian factors involved

Publikováno v: Proceedings of the International workshop on cocoa breeding for improved production systems, 19th-21th October 2003, Accra, Ghana

The prediction of the general combining ability (GCA), from the performance of accessions per se in germplasm collections, and the methodologies of analyses that can improve the efficiency of evaluation, are important points to be investigated in the

Publikováno v: Proceedings of the International workshop on cocoa breeding for improved production systems, 19th-21th October 2003, Accra, Ghana

The study presented in this paper consisted of three comparisons between the performances of 23 clones evaluated in five clonal trials and their performances as progenitors in three progeny trials in Côte d'Ivoire, for yield, vigour and yield effici
