摘要:

A zebra disease resistance factor has been incorporated into the high-yieldingAgavehybrid no. 11648 by crossing this hybrid withA. lespinassei. The progeny of three crosses have been screened for resistance toPhytophthora nicotianae, the chief pathogen of zebra disease and results show that 56.7% of the plants have sufficient resistance to be of economic value. The two screening techniques used are described, and the nature of the resistance factor discussed.
