Book excerpt: Os programas de melhoramento da batata (Solanum tuberosum L.) têm como objetivo produzir clones superiores que resultam de cruzamentos entre pares de diferentes genitores. Visando à obtenção desses clones superiores, são realizados, normalmente, experimentos que avaliam um número excessivo de clones, mas não avaliam as famílias. Em conseqüência da escassez de informações sobre dimensionamento de famílias, objetivou-se com este trabalho determinar tamanhos adequados de famílias para a avaliação das mesmas nesses programas, considerando-se as estimativas de parâmetros genéticos, e comparar a seleção entre famílias e a seleção de clones, verificando-se a viabilidade desses tipos de seleção. Para isso, foram utilizadas 25 famílias clonais representando uma ampla gama de materiais genéticos, pertencentes ao Programa de Melhoramento Genético da Batata da Universidade Federal de Lavras (UFLA). Utilizou-se o delineamento látice triplo 5 x 5. Cada parcela foi composta por 30 clones distribuídos em 3 linhas de 10 plantas cada uma. Foram avaliados os seguintes caracteres: produção de tubérculos por planta, porcentagem de tubérculos graúdos, peso médio de tubérculos graúdos, peso médio de tubérculos médios e peso específico de tubérculos. Dessa forma, pode-se concluir que as estimativas dos coeficientes de variação experimental (CVe), coeficientes de variação genética (CVg), herdabilidade e relação CVg/CVe estabilizaram-se a partir de dois clones por parcela significando que a representatividade das famílias pode ser feita com um número pequeno de clones; pelo método da curvatura máxima, as famílias poderiam ser representadas por aproximadamente 36 clones por família; a variância genética dentro de famílias foi maior que a variância genética entre famílias, para todos os caracteres, indicando um potencial favorável à seleção dentro de famílias; a correlação das médias das famílias com os 5%, 10%, 15% e 20% melhores clones de cada família, considerando-se as cinco características avaliadas, foi sempre crescente, significando que as melhores famílias possuem, de modo geral, os melhores clones.

Download or read book The Potato Crop written by Hugo Campos and published by Springer Nature. This book was released on 2019-12-03 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY 4.0 license. This book provides a fresh, updated and science-based perspective on the current status and prospects of the diverse array of topics related to the potato, and was written by distinguished scientists with hands-on global experience in research aspects related to potato. The potato is the third most important global food crop in terms of consumption. Being the only vegetatively propagated species among the world’s main five staple crops creates both issues and opportunities for the potato: on the one hand, this constrains the speed of its geographic expansion and its options for international commercialization and distribution when compared with commodity crops such as maize, wheat or rice. On the other, it provides an effective insulation against speculation and unforeseen spikes in commodity prices, since the potato does not represent a good traded on global markets. These two factors highlight the underappreciated and underrated role of the potato as a dependable nutrition security crop, one that can mitigate turmoil in world food supply and demand and political instability in some developing countries. Increasingly, the global role of the potato has expanded from a profitable crop in developing countries to a crop providing income and nutrition security in developing ones. This book will appeal to academics and students of crop sciences, but also policy makers and other stakeholders involved in the potato and its contribution to humankind’s food security.

Download or read book Potato Breeding Theory and Practice written by John E. Bradshaw and published by Springer Nature. This book was released on 2021-04-09 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potato (Solanum tuberosum) is the world’s fourth most important food crop after maize, rice and wheat with 377 million tonnes fresh-weight of tubers produced in 2016 from 19.2 million hectares of land, in 163 countries, giving a global average yield of 19.6 t ha-1 (http://faostat.fao.org). About 62% of production (234 million tonnes) was in Asia (191), Africa (25) and Latin America (18) as a result of steady increases in recent years, particularly in China and India. As a major food crop, the potato has an important role to play in the United Nations “2030 Agenda for Sustainable Development” which started on 1 January 2016 (http://faostat.fao.org). By 2030 the aim is to “ensure access by all people, in particular the poor and people in vulnerable situations, including infants, to safe, nutritious and sufficient food all year round”. By then, the world population is expected to reach 8.5 billion and continue to increase to 9.7 billion in 2050. For potatoes, the need is to increase production and improve nutritional value during a period of climate change, a key aspect of which will be the breeding of new cultivars for a wide range of target environments and consumers. The aim of the book is to help this endeavour by providing detailed information in three parts on both the theory and practice of potato breeding. Part I deals with the history of potato improvement and with potato genetics. Part II deals with breeding objectives, divided into improving yield, quality traits and resistance to the most important diseases and pests of potatoes. Part III deals with breeding methods: first, the use of landraces and wild relatives of potato in introgression breeding, base broadening and population improvement; second, breeding clonally propagated cultivars as a way to deliver potato improvement to farmers’ fields; third, as an alternative, breeding potato cultivars for propagation through true potato seed; and fourth, gene editing and genetic transformation as ways of making further improvements to already successful and widely grown cultivars. Included are marker-assisted introgression and selection of specific alleles, genomic selection of many unspecified alleles and diploid F1 hybrid breeding.
