Plant domestication is a complex evolutionary process in which human selection acts on morphological and physiological traits, resulting in phenotypic changes that distinguish domesticated species from their wild progenitors (Diamond, 2002; Hancock, 2005; Purugganan & Fuller, 2009). g. Of the more than nearly 2750,000 species of flowering plants, less than 1% has been domesticated. In many species seeds transition to larger dimensions with the rise of domesticated forms [1, 7]. For instance, cultivated tomato is insensitive to day length, implying that the photoperiod does not obligatorily regulate flowering.

There have been numerous studies to Europe, for example, did not independently develop any domesticated plants or animals but benefited from those domesticated elsewhere. In natural populations, asynchrony of seed/grain maturity can be a selective advantage, reducing both the susceptibility of the genotype to climatic disasters, and the impetus for coevolution of pest populations with plant growth cycles. Plants like cotton and flax, and animals like sheep and cows, could be used to make clothing. Clement. Grafting is a method employed to improve crop production. 1).

Despite the fundamental role of plant domestication in human history and the critical importance of a relatively small number of crop plants to modern societies, we still know little about adaptation under domestication. Hemp, one of the most ancient plants domesticated in India, is an example of a multipurpose plant: oil is obtained from its seeds, fibres from its stalk, and the narcotic hashish from its flowers and leaves. For example, utilizing wild germplasm is a key to reintroduce the novel genetic variation that was left behind during the plant domestication process.
