Yield and Fiber Quality Test of Cotton Mutant Lines In Bogor

Abctract:

Cotton is normally grown only in dry climate areas to obtain optimal production. In order to increase national production, it is necessary to extend production centers to su-optimal areas.

This experiment was conducted to determine yield and fiber quality of several cotton mutant lines in wet climate areas as West Java. The materials used are five mutant lines (1a, 2a, 4a,2c and 3a) derived of embryo axis in-vitro cultured of NIAB 999 cotton variety. The experiment was conducted at Babakan Madang, Cibinong, Bogor on November 2010 to February 2011, utilizing Randomized Block Design with four replications. Kanesia 8 and Kanesia 9 were usde as control varieties, and Niab 999 as parent control. The parameters observed were days of maturity, plant height, number of fruit/plant, production, also fiber length, strength, smoothness and uniformity. The result showed that mutant lines 2a and 3a were significantly shorter in plant height and matured earlier compared to Kanesia 8 and Kanesia9. Fiber length from all mutant lines was higher than both national control varieties and also the parent. Harvesting time of all mutant lines was a bit earlier although the productions of all lines tested were not significantly different.
