The grain amaranths were important food crops for the ancient middle and South American civilization. The germplasm of amaranths also has not been well characterized from the point of view of its exploitation for improvement of amaranths in general, a grain amaranth in particular. Among all under exploited crops grain amaranth is the most suitable candidate to begin with. As it is one of the most important under exploited crops being used as subsidiary or supplementary food. This work will report a study concerning the patent related to the biotechnological applications of Amaranths. It has been summarized in results that RAPD is a powerful approach to understand both inter-as-well as intra species relationships in the genus amaranths. One result indicates the presence of at least two repetitive families, such that at least one family of sequences is present in both cot1 as well as total nuclear DNA. The grain amaranth cultivation plays an important role in changing the economy of rural life. It is a source of dietary protein in strictly vegetarian people. In amaranths, somatic hybridization can be combined to the tertiary gene pools. Some of amaranth triploids are reported to be good in (Sharma SK, Dawson IK and Waugh R 1995) foliage and nutritional quality. They have broader leaves and good growth. Amaranth is grown under variety of soils and environmental conditions such as alkalinity, salinity, drought, frost etc. One of the ways to improve quality of grain amaranths to isolate variants of lysine genes products of which are enriched in essential amino acids. The high lysine content gene named as 'amargene' has been isolated and the patents have been used as biotechnological approach to introduce the gene in the tuber crop improvement The scope of biotechnology for the genetic improvement of grain amaranth crop has been described.
籽粒苋是古代中美洲和南美洲文明的重要粮食作物。从总体上利用苋属植物种质改良苋属植物，特别是籽粒苋的角度来看，苋属植物的种质也尚未得到很好的鉴定。在所有未充分利用的作物中，籽粒苋是最适合首先开展研究的候选作物。因为它是最重要的未充分利用作物之一，被用作辅助或补充食物。这项工作将报告一项关于籽粒苋生物技术应用相关专利的研究。结果总结表明，随机扩增多态性DNA（RAPD）是了解苋属植物种间和种内关系的有力方法。一个结果表明至少存在两个重复家族，使得至少一个序列家族同时存在于cot1和总核DNA中。籽粒苋种植在改变农村生活经济方面发挥着重要作用。它是严格素食者膳食蛋白质的来源。在苋属植物中，体细胞杂交可以与第三基因库相结合。据报道，一些苋属三倍体在（夏尔马·SK、道森·IK和沃augh·R，1995年）叶片和营养品质方面表现良好。它们有更宽大的叶子和良好的生长状况。苋属植物能在各种土壤和环境条件下生长，如碱性、盐性、干旱、霜冻等。提高籽粒苋品质的方法之一是分离赖氨酸基因的变体，其产物富含必需氨基酸。名为“amargene”的高赖氨酸含量基因已被分离出来，这些专利已被用作生物技术方法，将该基因引入块茎作物改良中。本文描述了生物技术在籽粒苋作物遗传改良方面的应用范围。
