》Certain self-pollinated crops like rice, wheat, sorghum, ragi (finger millet), potato, tomato, groundnut, red gram, and chillies do not show inbreeding depression, may be due to their evolution. Both male (stamens with anthers) and female (ovule) parts are located in the same flower, favoring self pollination before the flowers open. Self-pollination helps retain the good characters of a selected superior variety for a long time.

Self pollinated species do not show any inbreeding depression and also do not show heterosis.
Explanation:
Inbreeding depression is defined as the reduction of biological fitness in specific population.
Self-pollination is the process in which pollen grains are transferred from the stigma of a flower to the ovule of same flower.
The self- pollinated species do not show inbreeding depression as they undergo self fertilisation and shows good characters of a selected superior variety for a long time. As a result of self fertilisation plants develop homozygous balance.
