ABSTRACT:
The present invention relates to a method for rapidly introducing genes into germplasm which involves the use of crossing, backcrossing, intense selection and agronomic trait selection. More specifically, the method comprises the steps of: (a) crossing two parents of two different species, one of the parents (the donor parent) contains the gene of interest; (b) backcrossing the resultant progeny with the parent not containing the gene of interest (recurrent parent) for two to four backcrosses; (c) performing intense selection on a segregating generation of the progeny from the backcrossing step; and (d) selecting final germplasm on the basis of desired agronomic traits. The present invention further relates to two new and distinctive high yielding Pima Bt (Bacillus thuringiensis) Bollgard.RTM. cotton cultivars, designated 926 B Pima and 930 B Pima, which have been prepared in accordance with the method of the present invention.
