Draft:Taro Breeding
Submission declined on 23 December 2023 by Cerebellum (talk). Interesting article! I don't think Wikipedia has any articles on the breeding of individual plants, typically we include this information as a section of the main article, for example Maize#Breeding or Wheat#Breeding objectives. So I recommend adding this information as a section of the main taro article.

Breeding[edit]
In the early 1970’s, one of the earliest taro breeding programs was initiated in the Solomon Islands to create cultivars that were resistant to taro leaf blight.After taro leaf blight was introduced to Samoa in 1993, another breeding program was initiated. In this program Asian varieties that were resistant to TLB were used. The breeding program helped restore the taro export industry in Samoa. [1].
Corm yield and corm quality appear to be negatively correlated. In order to produce the uniform fresh healthy corms that the market desires, early maturing cultivars with a growth period of 5 to 7 months can be used.[1]
Selection methods and programs[edit]
Cultivars grown in the pacific produce good quality corms, as a result of selecting for corm quality and yield. However, the genetic bases of these cultivars is very narrow. Asian cultivars have agriculturally undesirable traits (such as suckers and stolon), but appear to be more genetically diverse. There needs to be an international exchange of taro germplasm with reliable quarantine procedures[1].
There are thought to be 15,000 varieties of C.esculenta. Currently there are 6,000 accession from various institutes from across the world. The INEA (International Network for Edible Aroids) already has a core sample of 170 cultivars that have been distributed. These cultivars are maintained in vitro in a germplasm centre in Fiji [2], which is considered safer and cheaper than field conservation[1].
Polyploidy breeding[edit]
Taro exists as a diploid (2n=28) and a triploid (3n=42).[citation needed] Naturally occurring triploids in India were found to have significantly better yields. There have been attempts to artificially make triploids by crossing diploids with artificial tetraploids[1]
