This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combining ability analysis for yield and its component traits was undertaken with five lines and 30 testers using Line x Tester mating design. The estimated components of variance for Specific Combining Ability (SCA) effectswere larger in magnitude than the General Combining Ability (GCA) effects for all the characters, indicating the predominance of non-additive gene action for control of these characters. The predominance of variance due to SCA over GCA showed that non-additive type of gene action was involved for all the traits studied. The estimates of GCA effects indicated that the parent ICMA 94111A1 was a good combiner for all the traits studied except the grain yield per plant. An overview of the mean performance and the GCA effects of parents revealed that the ICMA 88004A and testers PT 5447, PT 5451 and PT 5480 were identified as good parents for further breeding program. The ICMA 88004A x PT 5433, 732A x PT 5172, ICMA 88004A x PT 5480, 81A x PT 5656 and PT 5054A x PT 5451 were identified as superior hybrids and can be effectively utilized for hybrid breeding programs.

This book was released on 2015-06-22 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1982 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: When trying to solicit authors for this book it became apparent that the causal factors for heterosis at the physiological and biochemical level are today almost as obscure as they were 30 years ago. Though biometrical-genetical analyses point to dispersion of complementary genes - not overdominance - as the major cause of the phenomenon, plant breeders' experience still suggests a cautious, pragmatic approach to the dominance-overdominance controversy in breeding hybrid cultivars. Thus we are faced with a striking discordance between our limited comprehension of the causal factors and mechanism of heter osis on the one hand, and the extensive agricultural practice of utiliza tion of hybrid vigor on the other. Such utilization is the result of the economic value of hybrid combinations displaying superior yields and qualities as well as stability of performance, of benefits derived in breeding programs, and of the enhanced varietal protection of proprietary rights. No comprehensive and critical analysis of the phenomenon of heterosis in economic plants has been published for the last three decades since the now classical book Heterosis, edited by J . W. Gowen (Iowa State College Press, Ames, Iowa, 1952). The present book attempts to fill the gap and to assess the status of our present knowl edge of the concept, the basis, the extent, and the application of heterosis in economic plants.
Download or read book Drought phenotyping in crops From theory to practice written by Philippe Monneveux and published by Frontiers E-books. This book was released on 2014-02-12 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: This topic is a unique attempt to simultaneously tackle theoretical and practical aspects in drought phenotyping, through both crop-specific and cross-cutting approaches. It is designed for – and will be of use to – practitioners and postgraduate students in plant science, who are grappling with the challenging task of evaluating germplasm performance under different water regimes. In Part I, different methodologies are presented for accurately characterising environmental conditions, implementing trials, and capturing and analysing the information this generates, regardless of the crop. Part II presents the state-of-art in research on adaptation to drought, and recommends specific protocols to measure different traits in major food crops (focusing on particular cereals, legumes and clonal crops). The topic is part of the CGIAR Generation Challenge Programme’s efforts to disseminate crop research information, tools and protocols, for improving characterisation of environments and phenotyping conditions. The goal is to enhance expertise in testing locations, and to stimulate the development and use of traits related to drought tolerance, as well as innovative protocols for crop characterisation and breeding.

This book was released on 2009 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The spread of modern varieties and hybrids of pearl millet and sorghum that began in the mid-1960s has had an important impact on small farmer welfare in India. The success and sustainability of these improved cultivars resulted from three types (or periods) of interventions by the Indian government: (1) increased investments in crop improvement by national and international agricultural systems during the 1970s; (2) development of efficient seed systems, with the gradual inclusion of the private sector in the 1980s; and (3) the liberalization of the Indian seed industry in the late 1990s. In addition to increased overall production levels of sorghum and millet, there have been substantial yield gains in semi-arid regions as well as improved cultivars adopted in some of the poorest areas of India. The innovations of new, hybrid technology have not been limited to the Green Revolution crops; they have also had significant impact on the productivity of small-farmer households growing dryland crops, such as millet and sorghum in India.
