ABSTRACT

Acala Sierra RR is a new, high yielding Roundup Ready Acala cotton variety for California's San Joaquin Valley. Over two years of testing by the San Joaquin Valley Cotton Board at fifteen locations, Acala Sierra RR yielded significantly more than Maxxa by 105 pounds of lint per acre. Fiber and spinning properties of Acala Sierra RR were equivalent to those of Maxxa. Supplies of Acala Sierra RR planting seed should be adequate in 2003.
