Strategies for Enhancement in Food Production Test 10

The potato is a starchy, tuberous crop from the perennial nightshade Solanum tuberosum. In the Andes (South America), where the species is indigenous, there are some other closely related cultivated potato species. Potatoes were introduced outside the Andes region approximately four centuries ago.

Inbreeding depression is the reduced biological fitness observed in a population due to inbreeding or breeding of related individuals. Self pollination is the transfer of pollen from Anther to the stigma of the same flower or another flower of the same plant, so it leads to inbreeding depression.

Any cell of the female gametophyte or sporophytic tissue around the embryo sac may give rise to an embryo and such embryos are called as non-zygotic embryos. Embryoid is a mass of plant tissue that resembles embryo. These are formed from single cells in tissue culture. So, Embryoid is called as a non-zygotic embryo.
