Morphological and chemical characterization of fruits of Capsicum spp. accessions

This study aimed to evaluate 69 Capsicum accessions from the Germplasm Bank of Universidade Federal de Roraima, for some fruit quality traits. The experiment was performed in a completely random design, with 69 treatments and 3 replications. The 69 accessions were evaluated for fourteen quantitative...

The experiment was performed in a completely random design, with 69 treatments and 3 replications. The 69 accessions were evaluated for fourteen quantitative and two qualitative traits of ripe fruits. Quantitative fruits data were subjected to an analysis of variance, and the means were grouped by Scott-Knott test (p&lt;0.01). All characteristics had significant effect of treatments (p&lt;0.01) for all evaluated traits. The data showed high genetic variability to future use in a Capsicum breeding program. The accessions 33, 44 and 41 showed major values for dry matter content and total soluble solids; these should be used to improve these traits in a paprika breeding program. On the other hand, the accession 48 showed major values for fresh weight, major fruit length and fruit width. The accession 33, belonging to the Capsicum frutescens species, with high vitamin C content should be used in a fresh market Capsicum breeding program. O objetivo deste trabalho foi caracterizar 69 acessos do gênero Capsicum, pertencentes ao Banco de Germoplasma de Hortaliças da Universidade Federal de Roraima, quanto a 16 descritores relacionados à qualidade de frutos. O experimento foi conduzido em campo, no delineamento experimental inteiramente casualizado, com três repetições e 10 plantas por parcela. Quatorze descritores quantitativos e dois qualitativos foram utilizados na caracterização e para obtenção de caracteres morfológicos de qualidade. Obteve-se a média de dez frutos por repetição, aleatoriamente dentro de cada acesso, quando os frutos atingiram a maturidade. Os dados quantitativos foram submetidos à análise de variância, com posterior agrupamento das médias pelo teste Scott-Knott. Houve diferença significativa (p&lt;0,01) entre os 69 acessos tanto para caracteres morfológicos quanto químicos dos frutos, podendo essa diversidade ser utilizada em programa de melhoramento de Capsicum. Se o programa de melhoramento visar à obtenção de maior rendimento de pó, indica-se o uso dos acessos 33, 44 e 41, cujos valores de teor de matéria seca e sólidos solúveis totais foram mais elevados. Entretanto, se o objetivo for o comércio de frutos in natura, recomenda-se o acesso 48 que apresentou maiores valores de matéria fresca, comprimento e diâmetro do fruto. O acesso 33, Capsicum frutescens, apresentou o maior teor de vitamina C.</description><identifier>ISSN: 0102-0536</identifier><identifier>EISSN: 0102-0536</identifier><identifier>DOI: 10.1590/S0102-05362011000300018</identifier><language>eng</language><ispartof>Horticultura brasileira, 2011-09, Vol.29 (3), p.364-371</ispartof><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c275t-f98af2f92faae8d1813ec6e7c81e8b04302b68371c4445b10224d2d2d5313f2d3</citedby><cites>FETCH-LOGICAL-c275t-f98af2f92faae8d1813ec6e7c81e8b04302b68371c4445b10224d2d2d5313f2d3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>777,781,27906</link.rule.ids></links><search><creatorcontrib>Rêgo, Elizanilda R do</creatorcontrib><creatorcontrib>Rêgo, Mailson M do</creatorcontrib><creatorcontrib>Matos, Izadora Wally F de</creatorcontrib><creatorcontrib>Barbosa, Lidiany Aparecida</creatorcontrib><title>Morphological and chemical characterization of fruits of Capsicum spp. accessions</title><title>Horticultura brasileira</title><description>This study aimed to evaluate 69 Capsicum accessions from the Germplasm Bank of Universidade Federal de Roraima, for some fruit quality traits.
