The mean performance of parents and their hybrids have been summarized in Table 1, which indicates that among the parents, FH-113 formed maximum bolls/plant, produced highest number of sympodial branches/plant and gave maximum seed cotton yield/ plant, highest seed index and ginned maximum lint%; the dwarfed plant with heavier bolls were recorded by the parent IR-1524.
The bolls are aspirated by bugs, and even if they manage to open, they have lighter seeds and therefore, making higher seed-lint ratio.
