sis and later falls from the plant. Pollination occurs with the opening of the anthers and shedding of pollen on the stigma or with the deposit of pollen on the stigma by insects.
Because cotton has both male and female organs on the same flower, cotton breeding techniques take advantage of the plant's ability to be bred by both self-pollination and cross-pollination. Self-pollination occurs when pollen from the male organ is transferred to a female organ on the same flower on the same plant. Self-incompatibility is a form of infertility caused by the failure of cotton plants with normal pollen and ovules to set seed due to some physiological hindrance that prevents fertilization. Self-incompatibility restricts self-pollination and inbreeding and fosters cross-pollination. Cross-pollination occurs when pollen from the male organ on the flower of one plant is transferred to a female organ on the flower on a different plant.
A plant is sib-pollinated (a type of cross-pollination) when individuals within the same family or line are used for pollination (i.e. pollen from a family member plant is transferred to the stigmas of another family member plant). Self-pollination and sib-pollination techniques are traditional forms of inbreeding used to develop new cotton varieties, but other techniques exist to accomplish inbreeding. New cotton varieties are developed by inbreeding heterozygous plants and practicing selection for superior plants for several generations until substantially homozygous plants are obtained. During the inbreeding process with cotton, the vigor of the lines decreases and after a sufficient amount of inbreeding, additional inbreeding merely serves to increase seed of the developed variety. Cotton varieties are typically developed for use in the production of hybrid cotton lines.
Natural, or open pollination, occurs in cotton when bees or other insects transfer pollen from the anthers to the stigmas and can include both self- and cross-pollination. Such pollination is accomplished almost entirely by the bees or other pollinating insects as the pollen is heavy and sticky and accordingly, interplant transfer of pollen by the wind is of little importance. Vigor is restored when two different varieties are cross-pollinated to produce the first generation (F1) progeny. A cross between two defined substantially homozygous cotton plant varieties always produces a uniform population of heterozygous hybrid cotton plants and such hybrid cotton plants are capable of being generated indefinitely from the corresponding variety cotton seed supply.

 Because cotton has both male and female organs on the like flower, cotton reproduction techniques carry advantage of the plant's ability to be bred by both self - pollination and cross - pollination. Self - pollination occur when pollen from the male organ is transferred to a female electric organ on the same flower on the same plant. Self - incompatibility is a form of infertility caused by the bankruptcy of cotton plants with normal pollen and ovules to set source due to some physiological hindrance that prevents fertilization. Self - incompatibility restrict self - pollination and inbreeding and fosters crabbed - pollination. Cross - pollination occur when pollen from the male organ on the flower of one plant is transferred to a female organ on the flower on a unlike plant. 
 A plant is sib - pollinated (a type of cross - pollination) when individuals within the same family or line are used for pollination (i.e. pollen from a family member plant is transferred to the stigmas of another family member plant). Self - pollination and sib - pollination techniques are traditional form of inbreeding used to develop modern cotton variety, but other techniques exist to accomplish inbreeding. newfangled cotton varieties are developed by inbreeding heterozygous plants and practicing survival for superior plants for several generations until substantially homozygous plants are receive. During the inbreeding process with cotton, the vigor of the lines decreases and after a sufficient sum of inbreeding, additional inbreeding merely serve to increase seed of the developed variety. Cotton varieties are typically developed for habit in the production of hybrid cotton lines. 
 Natural, or loose pollination, occurs in cotton when bees or other insects transmit pollen from the anthers to the stigmas and can admit both self- and cross - pollination. Such pollination is accomplished almost entirely by the bee or other pollinating worm as the pollen is heavy and sticky and accordingly, interplant transfer of pollen by the wind is of small importance. Vigor is restored when two unlike varieties are cross - pollinated to produce the beginning coevals (F1) progeny. A cross between two defined well homozygous cotton plant varieties always produces a uniform population of heterozygous hybrid cotton plants and such hybrid cotton plants are capable of being beget indefinitely from the corresponding variety cotton seed supply.
