... of diploid and tetraploid

[Dinesh Valke]

Dear friends,
... while searching for Gossypium hirsutum on the internet, found lot of matter that enlightened me ... for instance, there are only four species among 42 which are cultivated, rest being of wild nature ... the four namely G. arboreum, G. herbaceum, G. hirsutum and G. barbadense.

The first two species are diploid ... and are native of old world ... the last two are tetraploid ... referred to as New world cottons.

G. hirsutum is the predominant species, which alone contributes about 90% to the global production.

... interesting reading at http://www.kapasindia.com/TMCOnline/root/common/GeneralCottonCul.asp

 

Attached is a 17 MAY 09 photo shot at a villager's backyard in Yeoor Hills, Sanjay Gandhi National Park, Thane, showing a burst cotton pod.

Would it tell us whether it belongs to diploid and tetraploid plant ?

 

Regards.
