Interpretive Summary: Seed cottons representing the plant bottom-, mid-, and upper-boll portions of the DP2115 variety were collected and ginned by using a 10-saw Dennis laboratory saw gin. The field had 4 sub-fields with different irrigation regimes (i.e., 1 non-irrigated field and 3 irrigated fields). When the combined quality data of bottom-, mid-, and upper-boll positions from the same area were analyzed, irrigated fields with different timing of irrigation showed significant increases in HVI UHML, UI, strength, and Rd as well as AFIS L(w), UQL(w), L(n), and L5%(n) property compared to non-irrigated field. Meanwhile, irrigation treatment indicated significant decreases in HVI SFI as well as AFIS neps, fineness, IFC, and MR. Principal component analysis (PCA) of standardized HVI qualities implied a separation of fibers between non-irrigated field and irrigated fields. Next, analysis of both HVI and AFIS data from either bottom- or mid- or upper-boll position revealed significant changes, from non-irrigated field to irrigated fields, for HVI UHML (Upper-bolls), UI (bottom- and mid-bolls), strength (mid-bolls), +b (bottom-bolls), and SFI ((bottom- and mid-bolls) as well as AFIS L(w) (bottom- and mid-bolls), UQL(w) (bottom- and mid-bolls), SFC(w) (mid-bolls), L(n) (bottom- and mid-bolls), L5%n (bottom- and mid-bolls), SFC(n) (mid-bolls), fineness (Upper-bolls), IFC (Upper-bolls), and MR (Upper-bolls). Although MIC varied significantly from bottom- to mid- to upper-bolls for both non-irrigated field and 2 of 3 irrigated fields, UHML changed significantly for non-irrigated fields whereas HVI UI and SFI as well as AFIS neps, L(w), SFC(w), L(n), SFC(n), fineness, IFC, and MR varied significantly for least 1 of 3 irrigated fields.
