Hybrid 4 ushered in the era of hybrid cotton in India in the 1970s.  Hybrids both intra and interspecific now occupy about 28% of the cotton area and contribute about 42% of production of the country.  Inspired by the unique success of hybrid cotton in India, researchers in many cotton growing countries intensified their research on hybrid cotton.  A sizeable area is devoted to F1 and F2 hybrids in China.  In many other countries F1 or F2 hybrids are a distinct possibility in the near future.  The high cost of seed, which is a deterrent for the development or spread of hybrids can be overcome by exploiting male sterile systems coupled with bee pollination.  For hybrids to be successful they should be very high yielding, early maturing, moderately resistant to biotic and abiotic stresses with good fibre properties and above all, they have to be more profitable than varieties to attract farmers to grow them.
