Sunflower hybrids were first developed in sunflower 60 years ago and with the discovery of cytoplasmic male sterility have become the main type of variety since 1970. Breeding programs use mostly pedigree, recurrent and backcross selection. The main characters selected for are seed yield, oil content and oil type, earliness, height, disease, insect and

Genetic variation within globe artichoke landraces contributes to the variable yield performance detected in cultivation. It was built up over many generations of vegetative propagation as a consequence of the limited selection applied by farmers as well as the accumulation of mutations.

Breeding and genetics of waterfowl
World's Poultry Science Journal, 2003Genetic parameters of traits of interest in ducks and geese are reported. Recent achievements of research, specially to improve the Brown Tsaiya laying duck; the intergeneric crossbreeding in duck; the meat ducks Pekin and Muscovy; the goose reproduction ability; the meat and fatty liver production in geese and ducks were analysed.

Although applications of breeding in tea are difficult, entire varietal development in tea and other Camellia species have been done through conventional breeding which started way back in 1939. Since then, several developments of genetics and breeding works have taken place, which are discussed in this chapter.

Amongst flowering plants the tomato is exceptionally well endowed for genetic and cytogenetic research. Its foremost attribute for such purposes, despite a relatively high haploid chromosome number (12), is its basic diploid nature. (Rick, 1971a). Abundant interplay between tomato genetics and tomato breeding has resulted in great mutual benefit and ...

Local breeds and genetic improvement
2006Genetic improvement is generally associated to large breeds and management of local small breeds is seen as maintenance of the current genetic profùe, however, selection programmes may increase sustainability oflocal breeds. The paper discusses some issues associated to selection in local breeds. First, in generai farm animal populations are under some
