HERE are now several cases reported in the literature in which the transfer a chromosomal segment from one species of Gossypium to another results in altered recombination frequency in the chromosome to which the “foreign” segment has been transferred (SILOW 1944; RHYNE 1958; PHILLIPS 1961; STEPHENS 1961). Further, it is known that the altered recombination may take the form of either increased...

Abstract Utilization of modern breeding techniques for developing high yielding and uniform plant types ultimately narrowing the genetic makeup most crops. Narrowed these crops has made them vulnerable towards disease insect epidemics. For sustainable crop production, variability must be broadened against various biotic abiotic stresses. One ways to widen configuration is identify novel additio...
