Pigeonpea (Cajanus cajan(L.) Millsp. is one of the most important legume crops as major source for proteins, minerals and vitamins, in addition to its multiple uses as food, feed, fuel, soil enricher, or soil binder, and in fencing, roofing and basket making. ICRISAT's genebank conserves 13,632 accessions of pigeonpea. The extensive use of few parents in crop improvement is contrary to the purpose of collecting a large number of germplasm accessions and has resulted in a narrow base of cultivars. ICRISAT, in collaboration with the Generation Challenge Program, has developed a composite collection of pigeonpea consisting of 1000 accessions representing the diversity of the entire germplasm collection. This included 146 accessions of mini core collection and other materials. Genotyping of the composite collection using 20 microsatellite or simple sequence repeat (SSR) markers separated wild and cultivated types in two broad groups. A reference set comprising 300 most diverse accessions has been selected based on SSR genotyping data. Phenotyping of the composite collection for 16 quantitative and 16 qualitative traits resulted in the identification of promising diverse accessions for the four important agronomic traits: early flowering (96 accessions), high number of pods (28), high 100-seed weight (88) and high seed yield/plant (49). These accessions hold potential for their utilization in pigeonpea breeding programmes to develop improved cultivars with a broad genetic base. Pigeonpea germplasm has provided sources of resistance to abiotic and biotic stresses and cytoplasmic-male sterility for utilization in breeding programmes.

The Impact

The sustainable development of the industrial enterprises in the Qaidam Circular Economy Pilot Zone must meet both the current needs and the future development, as well as the economic and ecological development, as well as the dual development of industrial enterprises and regions. For the industrial enterprises in the experimental area, in order to ensure sustainable development, their own strategies and efforts are very important, but in a policy-dependent area like Haixi Prefecture, the influencing factors of the objective environment are more important. The impact of sustainable development of HaiXi industrial enterprises is of great practical significance. Therefore, according to the subjectivity of Haixi Prefecture and the experimental area and the nature of industrial enterprises, the objective environmental factors are divided into four categories: regional development, regional material resources, regional greening, and regional security. In the end, it was concluded that industrial enterprises in the test area not only need to pay attention to the restraint of their sustainable development in terms of brain drain, energy consumption and environmental greening, but also continue to maintain the role of regional development and regional security in promoting their sustainable development.

Abstract Genotyping of lentil plant genetic resources holds the promise to increase the identification and utilization of useful genetic diversity for crop improvement. The International Center for Agriculture Research in the Dry Areas (ICARDA) lentil reference set plus collection of 176 accessions was genotyped using genotyping-by-sequencing (GBS) and 22,555 SNPs were identified. The population structure was investigated using Bayesian analysis (STRUCTURE, k = 3) and principal component analysis. The two methods are in concordance. Genome-wide association analysis (GWAS) using the filtered SNP set and ICARDA historical phenotypic data discovered putative markers for several agronomic traits including days to first flower, seeds per pod, seed weight and days to maturity. The genetic and genomic resources developed and utilized in this study are available to the research community interested in exploring the ICARDA reference set plus collection using GWAS.

High Yielding Varieties

Pepper (Capsicum spp.) is one of the major vegetable crops grown worldwide largely appreciated for its economic importance and nutritional value. This crop belongs to the large Solanaceae family, which, among more than 90 genera and 2500 species of flowering plants, includes commercially important vegetables such as tomato and eggplant. The genus includes over 30 species, five of which (C. annuum, C. frutescens, C. chinense, C. baccatum, and C. pubescens) are domesticated and mainly grown for consumption as food and for non-food purposes (e.g., cosmetics). The main challenges for vegetable crop improvement are linked to the sustainable development of agriculture, food security, the growing consumers’ demand for food. Furthermore, demographic trends and changes to climate require more efficient use of plant genetic resources in breeding programs. Increases in pepper consumption have been observed in the past 20 years, and for maintaining this trend, the development of new resistant and high yielding varieties is demanded. The range of pathogens afflicting peppers is very broad and includes fungi, viruses, bacteria, and insects. In this context, the large number of accessions of domesticated and wild species stored in the world seed banks represents a valuable resource for breeding in order to transfer traits related to resistance mechanisms to various biotic stresses. In the present review, we report comprehensive information on sources of resistance to a broad range of pathogens in pepper, revisiting the classical genetic studies and showing the contribution of genomics for the understanding of the molecular basis of resistance.

Proso millet (Panicum miliaceum L.) is a rich source of protein, minerals, and vitamins, and is an important cereal crop of Asia and Africa. Due to its lowest water and nutrient requirement, it has the potential for agriculture diversification. The development of a core collection would assist in efficient management and enhanced utilisation of proso millet genetic resources. The present investigation was conducted to develop a core collection of proso millet based on geographic information and 20 qualitative and quantitative traits recorded on 833 accessions conserved in the International Crops Research Institute for the Semi-Arid Tropics genebank. The entire germplasm collection was stratified into five groups based on races and data on 20 morpho-agronomic traits were used for clustering following Ward’s method. About 10% (or at least one accession) was randomly selected from each of 101 clusters to constitute a core collection of 106 accessions. Comparisons of means, variances, frequency distribution, diversity indices, and correlation studies indicated that the variation in the entire collection has been preserved in the core collection. This core collection provides a gateway to identify diverse trait-specific germplasm accessions for important agronomic traits and for abiotic and biotic stresses for use in crop improvement research and in crop diversification programs.
