Interpretive Summary: This paper documents the introduction and testing of both insect resistant and herbicide resistant genes into Acala 1517 germplasm. Acala 1517 germplasm is of very high fiber quality. The successful inclusion of both insect and herbicide resistance into this elite breeding line has the potential of significantly improving the productivity and quality of US cotton.
Technical Abstract: Through backcross breeding, insect resistant Bt genes (W and BGII) and herbicide resistant Roundup Ready genes (RR and RF) have been introduced into Acala 1517 cotton, resulting in the development of one Acala cultivar 1517-99W and a number of elite breeding lines. Acala 1517 germplasm with two Bt genes - WideStrike (W), RR and W/RR have been tested in multiple environments since 2003, while Acala 1517 with BGII/RF were tested in 2007.
