Starch is the leading component of wheat (Triticum spp.) grain and flour. Six hexaploid wheat (T. aestivum L.) near‐isogenic lines (NILs), WQL19WX7A (Reg. no. GS‐192, PI 691847), WQL19WX4A (Reg. no. GS‐193, PI 691848), WQL19WX7D (Reg. no. GS‐194, PI 691849), WQL19WX7A.A4 (Reg. no. GS‐195, PI 691850), WQL19WX7A.7D (Reg. no. GS‐196, PI 691851), and WQL19WX4A.7D (Reg. no. GS‐197, PI 691852), were developed to facilitate studies examining the role of starch amylose and amylopectin on wheat processing and end‐product quality and as parents to develop reduced amylose germplasm. Each NIL lacks a functional copy of one or two of the Waxy granule bound starch synthase I (GBSSI) genes and conversely possesses one or two functional genes. These genetic stocks were produced in ‘Alpowa’ soft spring wheat. The NILs are BC₇ sibs, selected among segregating BC₇ progeny using allele‐specific primers. The GBSSI null alleles were derived from the waxy cultivar Waxy‐Pen (PI 637779). These NILs are complemented by wild‐type Alpowa and a full waxy (zero amylose) line approved for release, ‘USDA Lori’. These lines were developed at the USDA Western Wheat Quality Laboratory.

六种缺乏一两个颗粒结合淀粉合酶I基因的部分蜡质近等基因六倍体小麦遗传种群的登记

淀粉是小麦（Triticum spp。）谷物和面粉的主要成分。六个六倍体小麦（T. aestivum L.）近等基因系（NIL），WQL19WX7A（Reg.no GS‐192，PI 691847），WQL19WX4A（Reg.no GS‐193，PI 691848），WQL19WX7D（Reg.No. GS-194，PI 691849），WQL19WX7A.A4（Reg。GS‐195，PI 691850），WQL19WX7A.7D（Reg。GS‐196，PI 691851）和WQL19WX4A.7D（Reg。 GS‐197（PI 691852）的开发旨在促进研究，研究淀粉直链淀粉和支链淀粉在小麦加工和最终产品质量中的作用，并作为开发还原型直链淀粉种质的亲本。每个NIL都缺少一个或两个Waxy的功能副本颗粒结合淀粉合酶I（GBSSI）基因，并拥有一个或两个功能基因。这些遗传资源是在“ Alpowa”软春小麦中生产的。NIL是BC ₇同胞，是使用等位基因特异性引物从BC ₇后代中分离出来的。GBSSI无效等位基因来自蜡质品种Waxy-Pen（PI 637779）。这些NIL辅以野生型Alpowa和获批准发布的完整蜡质（零直链淀粉）品系“ USDA Lori”。这些品系是在美国农业部西部小麦质量实验室开发的。
