heterosis,   etc   ; genetic improvement; ideotypes; rapeseed;     Show all 4 Subjects
Abstract:
... Over the past few years, rapeseed yields have been considerably lower than those of cereal crops, and progress has been slow due to its limitations for genetic improvement. Here, we propose a comprehensive strategy to consider the interactions between genetics, management practices, and environment, concentrating on using ideotype and heterosis to maximize yield. ...

Abstract:
... Genetic improvement of crop plants is a continuous process and plant breeders continuously strive for developing new varieties, which are high yielding and superior to the existing ones. The success of a breeding programme lies in the choice of appropriate parents and the breeding method followed. Therefore, the experiment was carried out involving gynoecious lines in cucumber at Palampur and Baja ...

Abstract:
... The Industrial Revolution led to replacing peasant mass selection by individual selection. In 1836 John Le Couteur on the suggestion of the Spanish botanist Mariano LaGasca codified the isolation method, empirically practiced since the early 19ᵗʰ century. It consists in replacing varieties or populations by “copies” of a better plant – by a (quasi) clone. It requires plants that “breed true to typ ...

Abstract:
... Heterosis (or hybrid vigor) has been widely used in crop seed breeding to improve many key economic traits. Nevertheless, the genetic and molecular basis of this important phenomenon has long remained elusive, constraining its flexible and effective exploitation. Advanced genomic approaches are efficient in characterizing the mechanism of heterosis. Here, we review how the omics approaches, includ ...

Abstract:
... In asparagus, current cultivars are mostly hybrids (known as clonal hybrids) derived from crosses between two parents, female and male, with good combining ability. Despite the fact that clonal hybrids have been obtained for more than 40 years, studies of the heterosis and combining abilities involved are limited. Similarly, there are no published studies regarding the association between genetic ...
