Genetic and Agro-Morphological Diversity and Genotype by Environment Interaction of Yield and Nutritional Quality Traits in Pearl Millet Germplasm from Sudan


Book Description

Due to its adaptation to extremely harsh environments, pearl millet (Pennisetum glaucum (L) R. Br.) is one of the most important staple cereals cultivated in the arid and semi-arid tropics of Asia and Africa. In these regions pearl millet is mainly produced under low-input, rainfed conditions in traditional farming systems, where several constrains are affecting pearl millet production, such as inter-annual rainfall variability, pests, diseases, Striga and use of low yielding varieties. The majority of the human population in these regions is affected by nutritional deficiencies of essential minerals causing micronutrient malnutrition (so-called ‘hidden hunger’). Plant genetic resources provide basic materials for selection and improvement of crop productivity through the optimal design of breeding programs to meet food security needs of the world’s rapidly rising population. The advent of PCR-based molecular markers such as simple sequence repeats (SSRs) has created an opportunity for fine-scale genetic characterization of germplasm collections. Understanding the structure of diversity and the identification of distinct materials with complementary traits for recombination by crossing provides the foundation for effective and sustained pearl millet population breeding and synthetic and hybrid development, based on the concept of heterotic groups in this allogamous crop.













To Study the Association of Various Morphological Characters with Forage Yield and Its Quality Under One Cut and Two Cut Management in Pearl Millet Pennisetum Americanum


Book Description

The study was conducted to findout highly correlated character with forage yield dry matter yield and its quality to estimate variability and heritability of different quantitative and heritability of different quantitative characters in the present material to find out direct and indirect effects of various component characters for dry matter yield and crude protein yield per plant and to identify the suitable selection functions for higher genetic advance in dry matter yield and its quality. High heritability was observed for the characters viz plant height leaf breadth stem girth NDF ADF HC and CC under cut 1 for characters days to harvest leaf length CP% NDF ADF HC and CC under cut 11 and for characters days to harvest leaf length DM% NDF ADF HC CC under single cut. Whereas medium heritability was observed for characters viz tiller number leaf length and cp per cent under cut 1 for plant height leaf oreadth and dry matter percent under cut 11 and for olant height leaf breadth leaf weight and cp per cent under single cut whereas other characters showed low heritability below 30 percent. Among morphological characters plant height under 11 and single cut showed higher expected gain. Overall picture of quality traits showed that NDF ADF and HC increased with maturity while cp and cc decreased with maturity.
