PSB-Ct10 Cotton Variety
PSB-Ct10 is a recommended cotton variety for commercial production in the Philippines. It was approved and released by the National Seed Industry Council on 23 February 1999.
A G. barbadense variety, PSB-Ct10 was introduced into the country from the Galapagos Island, South America in 1988 as part of then CRDI (now CODA) germplasm collection. It has long, strong and silky fiber which is used in the production of luxury fabrics and sewing threads. Locally, the demand for long-stapled cotton is 10% of the total lint requirements of textile mills. Its unique properties make it globally competitive.
Yield Performance and Other Agronomic Characters
PSB-Ct10 yields 1.304 metric tons seedcotton per hectare. Each plant produces an average of 10 bolls, each boll weighs an average of 3.08 grams.
At maturity, PSB-Ct10 reaches 126.5 cm height. Flossing occurs at 138 days after emergence. Its earliness index is 46.54%.
Lint Recovery and Fiber Properties
PSB-Ct10 has high lint recovery averaging 28.68%. Its fibers are long (37.04mm), strong (27.99 g/tex), fine (<2.5ug/in) and silky.
Resistance to Major Cotton Pests and Diseases
PSB-Ct10 possesses a built-in protection against soil-borne pathogens. It is highly resistant to Sclerotium rolfsii and resistant to Rhizoctonia solani, two prevalent species that cause damping-off disease in cotton seedlings. Likewise, it is highly resistant to bollworm and leafhopper.
Adaptability
After several field tests, this commercial variety is adapted to cotton production areas in Luzon. It can tolerate drought stress and saline conditions like that in Candon, Ilocos Sur under the following cultural management practices:
