This article explores possible future initiatives, such as the development of targeted breeding and integrated omics approach to boost kodo millet production, nutritional value, and environmental adaptation. Kodo millet is grouped under the genus Paspalum and family Gramineae. It is a tropical African crop that was initially domesticated in India approximately 3000 years ago. It is predominantly cultivated in India as well as in various south-east Asian countries. Recent years have witnessed a resurgence of interest in kodo millet breeding, particularly owing to its outstanding nutritional profile. Kodo millet's ability to adapt to different marginal environments makes it promising to be grown as a part of sustainable agriculture. Availability of a plethora of diverse genetic resources in kodo millet has been instrumental in development of various improved cultivars through conventional breeding. Additionally, functional genomics has been instrumental in decoding the complex genetic architecture of kodo millet, thus enabling identification of key genes associated with drought tolerance, disease resistance, and improved nutritional profiling. Additionally, transcriptomics has deepened the insights into gene expression pattern in response to various stresses, offering valuable information for developing resistant genotypes. The expressed sequence tags (ESTs) available will surely benefit the scientists working on molecular breeding of millets through development and use of SSRs and SNPs markers under the marker assisted selection (MAS) scheme. This article examines potential directions for future research, including the advancement of genomics and targeted breeding approaches for holistic development of the kodo millet.
本文探讨了未来可能采取的举措，例如开发定向育种和综合组学方法，以提高科多谷的产量、营养价值和环境适应性。科多谷属于雀稗属禾本科。它是一种热带非洲作物，大约在3000年前最初在印度被驯化。它主要在印度以及东南亚各国种植。近年来，人们对科多谷育种的兴趣再度兴起，特别是由于其出色的营养成分。科多谷适应不同边缘环境的能力使其有望成为可持续农业的一部分。科多谷中大量多样的遗传资源有助于通过传统育种培育出各种改良品种。此外，功能基因组学有助于解读科多谷复杂的遗传结构，从而能够鉴定与耐旱性、抗病性和改善营养成分相关的关键基因。此外，转录组学加深了对基因在应对各种胁迫时表达模式的理解，为培育抗性基因型提供了有价值的信息。现有的表达序列标签（EST）肯定会通过在标记辅助选择（MAS）方案下开发和使用SSR和SNP标记，使从事谷子分子育种的科学家受益。本文研究了未来研究的潜在方向，包括基因组学的进展以及科多谷全面发展的定向育种方法。
