Biodiversity management in chickpea

Chickpea Breeding and Management, 2007

Variation in cultivated chickpea is mostly noted in the separation of the kabuli large-seeded and the desi small-seeded gene pools, each with associated patterns of traits (Moreno and Cubero, 1978). The desi types have seed size generally in the range 10–25 g/100 seed, and are associated with small leaves or leaflets, and small pods with 1–3 seeds that are angular-shaped or beaked. Seeds vary in colour from cream to orange, dull green, various shades of brown to black, and flowers usually vary from pink to red, blue veined and purple. In the ...

Chickpea (Cicer arietinum L.) Cytogenetics, Genetic Diversity and Breeding

2019

Climate change, depleting natural resources, declining arable land and sky-high population represent the main obstacles to the attainment of global food security. Therefore, to make a significant breakthrough in the food production and to combat global food insecurity, sustainable intensification of the agricultural production through low-input agriculture and development of cultivar with improved yield and adaptability is required. By traditional and modern plant breeding methods , breeding of pulses, cereals, and other important food crops, especially chick-pea, can be accomplished by exploiting available genetic diversity. Chickpea and other pulse crops are important foods in many nations and play a vital role in the diet of malnourished populations world wide. Globally, chickpea is mainly grown in developing countries, accounting for ~97% of world area and 96% of world production. At present the average global yield of chickpea is 0.9 mt/ha, very low com-paredto its estimated potential of 6 mt/ha under favorable growthconditions. The main constraints that limit desired goals of chick peaproductivity include low genetic variability, low and unstable yield and low resistance to biotic and abiotic

Genomic tools and germplasm diversity for chickpea improvement

Plant Genetic Resources, 2011

Chickpea is the third most important grain legume grown in the arid and semi-arid regions of the world. In spite of vast germplasm accessions available in different genebanks, there has been very limited use of these accessions in genetic enhancement of chickpea. However, in recent years, specialized germplasm subsets such as global composite collection, core collection, mini core collection and reference set have been developed. In parallel, significant genomic resources such as molecular markers including simple sequence repeats (SSRs), single nucleotide polymorphisms (SNPs), diversity arrays technology (DArT) and transcript sequences, e.g. expressed sequence tags, short transcript reads, have been developed. By using SSR, SNP and DArT markers, integrated genetic maps have been developed. It is anticipated that the use of genomic resources and specialized germplasm subsets such as mini core collection and reference set will facilitate identification of trait-specific germplasm, tr...
