ABSTRACT
PSC 57 Pima is a new, high yielding Pima cotton variety for California's San Joaquin Valley. Over five years of testing by Phytogen at sixteen locations, PSC 57 yielded more than Pima S7 (the San Joaquin Valley Cotton Board standard Pima variety) by one hundred pounds of lint per acre (an increase of more than ten percent). Over three years of testing by the San Joaquin Valley Cotton Board at nine locations, PSC 57 yielded more than S7 by nearly two percent. PSC 57 fiber and spinning properties were superior to those of S7 with greatly reduced manufacturing waste. PSC 57 planting seed will be readily available in 1999.
