Interpretive Summary: Currently, there are two instrumental systems being used to measure cotton fiber quality. One system is called ‘High Volume Instrument’ (HVI), and another system is called ‘Advanced Fiber Information System’ (AFIS). The purpose of this study is to determine efficiency of the two systems in breeding and give suggestions to cotton breeders when and how the two systems should be used. Plants in genetic populations were selected based on fiber properties measured by HVI and AFIS and evaluated from 2012 to 2016. The efficiency of the two systems in breeding was compared. Results indicate that the two systems are equally efficient in breeding for fiber length and maturity but different in short fiber content. Therefore, it will be breeder’s decision whether only HVI-fiber properties are used in selection considering its much lower cost than AFIS-fiber properties.

Technical Abstract: Fiber properties measured by high volume instrument (HVI) and advanced fiber information system (AFIS) are currently being used in Upland cotton (Gossypium hirsutum L.) breeding. It would be interesting to know if selections for parameters measured by the two instrumental systems are equally efficient, and if the selection responses between the two systems are correlated. A study was designed to determine the correlated selection responses between fiber properties measured by the two systems in F3, F4, and F5 generations of two crosses, FM 832 × SP 205 and MD 52 × JJ 1145ne. Selections for HVI-fiber length, HVI-short fiber content, and HVI-maturity were made in the F3 generation and the correlated responses of AFIS-fiber properties to the selections were estimated in the subsequent F4 and F5 generations. Selections for AFIS-fiber length, AFIS-short fiber content, and AFIS-maturity were made in the F4 generation and the correlated responses of HVI-fiber properties to the selections were estimated in the F5 generation. Moderate to high realized heritability was identified for both HVI- and AFIS-fiber properties. Significant correlated selection responses of fiber length and maturity between the HVI and AFIS methods were consistently observed in both crosses. The results suggest that HVI and AFIS measured the same genetic basis for fiber length and maturity. Therefore, equal effectiveness is expected of the selections for both traits by the two instrumental systems. Correlated selection responses of short fiber content parameters between the HVI and AFIS methods were not consistent. This result suggests that genetic basis of short fiber content parameters measured by the two systems may be different.
