摘要

A majority of people in India are vegetarian and depend on agriculture for their food, nourishment and clothes. Though the country has attained self-reliance in food-grains production, there is a shortage of edible oil, fruits, vegetables, condiments, spices, etc. The average yield of the crops providing these commodities in the country is much below the expected one. The simple reason is the failure of these crops due to inadequate pollination. All the crop plants are angiosperms, i.e. they bear flowers. For setting-up of seed/fruit, the flower must be pollinated, i.e. pollen must be transferred from the anther (male part) to the stigma (female part). If the flower utilizes its own pollen for seed set, this is called self-pollination (autogamy), and if the pollen comes from other flower(s), it is called cross-pollination (xenogamy). Most of the crops proriding the above commodities need cross-pollination of their flowers due to the presence of strong reproductive barriers. These include self-incompatibility, differential maturity of the reproductive organs and unisexuality. Under these barriers, a flower is not able to utilize its own pollen.
