Cottonscope使用少量纤维样品同时测量棉纤维的成熟度和细度。设计了一个测试程序，以确定Cottonscope的潜力和能力，快速，准确地测量少量近等基因棉花品系（NIL）的成熟度和细度，并检查使用Cottonscope成熟度分布育种应用。对来自两对近等基因系（MD 52 ne与MD 90 ne; TM-1与低成熟度im）的不同开花后天数（DPA）的成熟和未成熟纤维进行了棉纤维显微镜测量。棉花成熟度和细度的模式，在棉花纤维发育过程中的每一个NIL测量的Cottonscope进行了比较，以更传统的方法（如先进的纤维信息系统（AFIS），一个旧的和目前更广泛使用的方法）。与AFIS结果相比，Cottonscope成熟度和细度结果对DPA增加的响应更大，并且Cottonscope成熟度值的模式与Fibronaire马克隆值的模式一致。近等基因系棉花成熟度分布的比较表明，IM的成熟度分布是非常不同的，表现出更低的成熟度值相比，其他线路的分布。结果表明，棉纤维显微镜是棉花育种工作者监测纤维成熟度和发育成熟期棉纤维细度的有效工具。
The Cottonscope simultaneously measures a cotton fiber’s maturity and fineness using a small amount of fiber sample. A program of testing was devised to establish the potential and capabilities of the Cottonscope to rapidly and accurately measure maturity and fineness of small quantities of near-isogenic cotton lines (NILs), and to examine the use of the Cottonscope maturity distributions for breeder applications. Cottonscope measurements were performed on mature and immature fibers of varying days post-anthesis (DPA) from two pairs of NILs (MD 52ne versus MD 90ne; TM-1 versus the low maturity im). The patterns of cotton maturity and fineness during cotton fiber development of each NIL measured by the Cottonscope were compared to those measured by more conventional methods (e.g. the Advanced Fiber Information System (AFIS), an older and currently more widely used method). The Cottonscope maturity and fineness results were much more responsive to increasing DPA than the AFIS results, and the patterns of Cottonscope maturity values were consistent with those of the Fibronaire micronaire. Comparisons of the Cottonscope maturity distributions among the NILs demonstrated that the maturity distribution for im was very different and exhibited much lower maturity values compared to the distributions of other lines. The results demonstrated that the Cottonscope is an efficient instrument for cotton breeders to monitor fiber maturity and fineness of developing and mature cotton fibers.
