Banana
Banana is growing in more than 150 countries and having more than 1000types which subdivided into 50 groups. It is a staple food for many countries and has a greater value in nutritional aspects
Kerala is bestowed with many varieties of Banana. My search ends with more than fifty varieties of Bananas including all groups. Here I am finding the evolutionary history of two important crops called Banana and coconut. But both belong to different Genus. It is very difficult to find the traces of similarities to two crops and maybe unnecessary to the academics. The evolution of plants always a fascinating subject to me. I believe the evolution of plants happens from one plant to another. So I studied the following characteristics of two crops.
Banana by FAO
                  It is a giant herbaceous plant with an apparent trunk that bends without breaking
The banana plant is not a tree. The banana has an underground stem with adventitious roots. The banana plant has large leaves that closely rolled up one over the other. Together they look like a trunk but they form only an apparent trunk. The flowers of the banana plant form a large spike. It is a herbaceous flowering plant and seedless ( parthenocarpic).
A finding from Bruce K Kirchoff states that in his paper named' Anatomy of the axis of the Banana 'as follows. - The structure and homology of the placental trichomes of the Musaceae are discussed, and I conclude that they are not homologous to the arils of the other Zingiberales - 
 In another article, it states that the banana plant is a tree-like perennial herb. It is an herb because it does not have woody tissues and the ariel part of the parent plant dies down to the ground after the growing season.
The variability observed in morphological traits is used to characterize banana plants. Wild species of bananas share the same body plant as cultivated bananas, except that they reproduce through both seeds and suckers.

Banana

 Kingdom: Plantae
                           Angiosperms
                           Monocots
  Order: Zingiberales                
  Family: Musaceae
  Genus: Musa

Coconut

Kingdom: Plantae
                          Angiosperms
                          Monocots
Order: Aracales
Family: Arecaceae
Subfamily:  Arecoideae
Genus : Cocos
Species : C. nucifera

The evolutionary history of coconut from Wikipedia is as follows
  The evolutionary history and fossil distribution of Cocos Nucifera and other members of the tribe cocoseae are more ambiguous than modern-day dispersal and distribution with its ultimate origin and pre-human dispersal still unclear. There are currently two major viewpoints on the origins of the genus cocos, one in the Indo-pacific and another in South America. The vast majority of cocos like fossils have been recovered generally from only two regions in the world; New Zealand and West-central India. However, like most palm fossils are still putative, as they are usually difficult to identify.
    The earliest cocos-like fossil to be found was cocos zeylanica a fossil species described from small fruits around 3.5 cm (1.4 in)*1.3 to 2.5 cm (0.51 to 0.98 in) in size recovered from the Miocene (~23 to 5.3 million years ago ) of NewZealand in 1926. Research on them is still ongoing to determine which of them ( if any) actually belong to the genus Cocos. 
    So my observation is relevant to this topic
During the survey, I identified the following bananas.

PLANT DISEASE

  Cowpea Mosaic        Casual organism: cowpea aphid borne mosaic virus Symptoms:first appears dark and light green patches  on leaf surface area.When the disease advances leaf become yellow and dry up.Affected plants have prominent leaf vein,smaller young leaves,stunted plant growth and distorted fruit.Aphid,whiteflies and thrips can transmit viruses from plant to plant on which they feed.Aphid feeding may cause the leaves and fruit to become distorted.Thrips cause severe damage to the young crop by sucking the           cellsap.Whiteflies also feeds on the under surface of the leaf.Disease will transmit through seeds having viruses . Control measures:No adequate control for mosaic disease only we can control vector transmission. *Use only healthy seeds *Spray malathion50EC@2ml/litre or Quinalphose25EC@1.25ml/litre *Spray botanicals like nee oil emulsion *Place yellow sticky trap in fields.

Banana conservation a need of the hour       Banana             Bananas are one of the major food crops widely cultivated in many countries. It belongs to the family Musaceae and genus Musa. Bananas globally rank fourth in the position after rice, wheat, and maize as food for human. They are grown in more than 130 countries worldwide.  Bananas are native to tropical southeastern Asia but are widely cultivated in the tropical region of other parts of the world. Banana is a herbaceous flowering plant arising from the underground rhizome.               Now the UN Food and Agriculture Organization (FAO) has warned that wild banana species are rapidly going extinct as Indian forests are destroyed while many farmers varieties are also disappearing from the fields. So it is very urgent to take a global effort to save the banana's gene pool                               The majority of cultivated bananas arose from the Eumusa group of species. This section is the biggest in the gen
