Registration of TTU 0782, an Upland Cotton Germplasm Line with Superior Fiber Quality

Abstract

Improvement of fiber quality is essential if cotton farmers in the United States are to compete in the world market. A high‐quality cotton (Gossypium hirsutum L.) germplasm designated as TTU 0782 (Reg. No. GP‐930, PI 659504) was developed and released by the Department of Soil Science, Texas Tech University, on 25 May 2010. TTU 0782 was derived from the cross of TTU 202‐1107B with ‘Acala 1517‐95’, and it possesses highly favorable fiber length, high fiber‐bundle strength, and a desirable fiber‐length uniformity index as determined by high‐volume‐instrument testing. In addition, TTU 0782 exhibits low short‐fiber content, a high maturity ratio, and low nep counts as determined by the Advanced Fiber Information System. Spinning tests indicate that TTU 0782 had improved yarn tenacity and fewer thin and thick places, fewer neps, and less hairiness of yarn when compared with previously registered germplasm lines from Texas Tech University and with ‘FiberMax 958’.
