Adaptability of tropical forages to California's Central Valley

Not available – first paragraph follows:

Warm-season forages, highly productive in the world's tropical and subtropical regions, have been grown in the southeastern United States, but only bermudagrass (Cynodon daclylon (L.) Pers.), sudangrass (Sorghum sudanense (Piper) Stapf.), and dallisgrass (Paspalum dilalatum) have been grown extensively in California. However, rhodesgrass (Chloris gayana Kunth). and kikuyugrass (Pennisetum clandestihum Hochst. ex Chiov.) have been rusted in California. Since 1950 many improved tropical forages have been developed, but until 1980 no effort had been made lo screen a wide selection of these forages to assess their adaptability lo California climates.
