Advances In Breeding Of Citrus Crop

Advances In Breeding Of Citrus Crop Ppt Traditional breeding methods used for genetic improvement of citrus cultivars and create new varieties, or to improve desired traits require a long time and is hampered by many difficulties and restrictions related with plant size and long juvenile phase of citrus, as well as female and or male sterility, polyembryony, heterozygosity, and. Citrus research and education center, institute of food and agricultural sciences, university of florida, lake alfred, fl 33809, usa interests: citrus breeding and genetics for variety improvement; genomic research to develop efficient ways to select improved plants and to enable cloning and manipulation of important genes; seedless variety development by mutation breeding and tissue culture.

Advances In Breeding Of Citrus Crop Introduction. the genus citrus encompasses a broad range of fruit crops of worldwide importance, including sweet orange (citrus sinensis [l.] osbeck), mandarin (c. reticulata blanco), grapefruit (c. paradisi macf.), and lemon (c. limon [l.] burm. f.), all of which are usually grown in modern citriculture as grafted trees on selected specialized rootstock cultivars. Fruit trees, such as citrus, apple, and peach, generally have long breeding periods, and the development of new varieties by conventional cross breeding typically requires at least a dozen years or more. this long breeding period is mainly due to the long juvenile phase and therefore breeding cycle of perennial trees. The aim of this special issue is to highlight recent advances in fundamental and applied research in the fields of citrus breeding, genetics, genomics, physiology, and field management leading to improved productivity and fruit quality. Citrus is one of the most important fruit crops worldwide. it is grown in more than 130 countries, mainly in tropical and subtropical areas. sweet orange represents about 60% of total citrus production , being marketed as fresh fruit or as processed juice. mandarins represent about 21% of total citrus fruit production and are intended for the.
