genetic control of self-incompatibility in oilseed rape (Brassica napus) by Usukuma Ufot Ekuere Download PDF EPUB FB2

In oilseed rape (Brassica napus L.) like in most oleaginous crops, seed oil content is the main qualitative determinant that confers its economic value to the harvest. Increasing seed oil content is then still an important objective in oilseed rape breeding.

In the objective to get better knowledge on the genetic determinism of seed oil content, a genetic study was undertaken in two genetic Genetic control of oil content in oilseed rape (Brassica napus L.) Article in Theoretical and Applied Genetics (7) December with 68 Reads How we measure 'reads' The use of self-incompatibility is an alternative in hybrid breeding of oilseed rape.

Unfortunately, stable self-incompatibility is recessive and phenotype-based selection is very difficult and time-consuming. The development of reliable molecular markers for detecting desirable plants with functional self-incompatible genes is of great Molecular approaches and selection based on molecular markers can allow breeders to overcome this limitation.

Self‐incompatibility is one of the most effective approaches to utilizing heterosis in oilseed rape around the world.

To evaluate the heterosis of double low self‐incompatibility, the possibility of combining seed yield and oil content, and the genetic effects of parents on their hybrid progenies, a 2‐year field trial using a 3 × 22 NC II mating design was conducted during the   Detection of self-incompatible oilseed rape plants (Brassica napusL.) based on molecular markers for identification of the class I Shaplotype Lenka Havlícková1, Eva Jozová1, Miroslav Klíma2, Vratislav Kucera2 and Vladislav Curn1 1Biotechnological Centre, Faculty of Agriculture, University of South Bohemia, Ceské Budejovice, Czech The use of self-incompatibility is an alternative in hybrid breeding of oilseed rape.

The transposition involved an exchange of interstitial homeologous regions on linkage groups N7 and N16, and its detection was made possible by the use of segregating populations of doubled haploid lines The swede (Brassica napus L. var. napobrassica Peterm) and turnip (Brassica rapa L.
