Resumo: Basmati-370 is one of the most preferred aromatic fine quality rice in the world market. It has a pleasant aroma, extra fine grain and a characteristic elongation after cooking, but it is susceptible to some pathotypes of Pyricularia grisea in Brazil. The objective of the present investigation was to assess the degree of blast resistance and some agronomic characteristics in the advanced generations of its somaclones. The evaluations were carried out in R5 to R9 generations, in field trials, in rice blast nursery and greenhouse. Significant variations in grain quality and other agronomic characteristics were not observed. However, some of the somaclones showed higher degree of blast resistance. Nineteen somaclones were registered in the Active Germplasm Bank of Embrapa-Centro Nacional de Pesquisa de Arroz e Feijão as new aromatic rice sources. Two somaclones, SCBAS04 and SBAS16, exhibited a high degree of partial resistance to blast, and were found to be superior to cv. Basmati-370 in aromatic grain characteristic.

Basmati-370 in aromatic grain characteristic.A cultivar de arroz aromático Basmati-370 é uma das preferidas no mercado mundial. Possui aroma agradável, grão extra-fino, e característica de alongamento após o cozimento; porém, é suscetível a alguns patótipos de Pyricularia grisea no Brasil. O objetivo do presente trabalho foi avaliar o grau de resistência à brusone, e algumas características agronômicas nas gerações avançadas de seus somaclones. Foram estudadas gerações R5 a R9, no campo, em viveiro de brusone e em casa de vegetação. Não foram observadas variações significativas na qualidade de grãos e outras características agronômicas. Entretanto, alguns somaclones apresentaram alto grau de resistência à brusone. Foram registrados no Banco Ativo de Germoplasma da Embrapa-Centro Nacional de Pesquisa de Arroz e Feijão 19 somaclones como novas fontes de arroz aromático. Dois somaclones, SCBAS04 e SBAS16, exibiram alto grau de resistência à brusone, e foram superiores à cultivar Basmati-370 quanto ao aroma.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirade Araújo, Leila GarcêsPrabhu, Anne Sitarama2002-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6446Pesquisa Agropecuaria Brasileira; v.37, n.8, ago. 2002; 1127-1135Pesquisa Agropecuária Brasileira; v.37, n.8, ago. 2002; 1127-11351678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6446/3503info:eu-repo/semantics/openAccess2014-07-23T17:40:41Zoai:ojs.seer.sct.embrapa.br:article/6446Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-23T17:40:41Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
