Relative Maturity of Nexgen Varieties

Relative maturity is an important characteristic for cotton varieties, and is commonly used by seed companies to promote varieties in the appropriate geographies and environment, and by growers to choose varieties adapted to their climate and growing conditions. A quantitative method to determine relative maturity among cotton varieties was published in the Beltwide proceedings by Speed et al. in 2004 that utilizes nodes above cracked boll (NACB) measurements to compare maturities of two or more varieties. This presentation will show the results of a maturity analysis of the Nexgen/Americot variety commercial lineup, as well as some experimental lines, and will cover all geographies across the Belt.
