2. Selecting orange-fleshed sweet potato genotypes using selection indices
RESUMO A deficiência de vitamina A é frequente nos países em desenvolvimento. Neste contexto, a batata-doce pode ser uma aliada na reversão desse quadro, uma vez que apresenta baixo custo de aquisição e elevada disponibilidade de mercado. Além disso, alguns genótipos apresentam polpa de coloração laranja, rica em betacaroteno, que é o precursor da

3. Odor-contributing volatile compounds of a new Brazilian tabasco pepper cultivar analyzed by HS-SPME-GC-MS and HS-SPME-GC-O/FID
Abstract The cultivar BRS Avai was originated from recurrent phenotypic selection in the original American cultivar Tabasco Macllhenny™, used in the worldly famous Tabasco pepper (Capsicum frutescens L.) sauce. The determination of the aroma profile of this new cultivar could reveal important qualitative descriptors that will help in future crosses and in

4. Productive potential and castor bean selection of the FCA-PB cultivar progenies
ABSTRACT Castor bean is a very important crop, however, in Brazil it still has relatively low productivity, 0.47 Mg ha-1 as a mean. Besides that the Country has significant castor oil demand and depends on international commerce to complement its production. The solution of these problems goes through the development of genotypes highly productive and adapte

7. Selection of high-yielding, adapted and stable wheat lines in preliminary trials
Abstract Experimental design without replication, such as Federer's augmented block design, allows us to determine productivity, adaptability and stability in multi-environment trials. This work aimed to select productive wheat lines with high adaptability and stability in preliminary trials. The grain yield of 140 homozygous wheat lines was measured in 2015

8. Natural convection drying kinetics of ‘Prata’ and ‘D’água’ banana cultivars (Musa ssp) by nonlinear regression models
Resumo A bananeira está entre as frutíferas mais plantadas em países tropicais e pertence ao grupo de frutos mais consumidos do mundo; entretanto, necessitam de técnicas de conservação adequadas. Objetivou-se descrever a cinética de secagem de bananas Prata e D’água nas temperaturas de 40 e 70°C, comparando os modelos de regressão Henderson, EST

9. Resistance of the wild tomato Solanum habrochaites to Phytophthora infestans is governed by a major gene and polygenes
Abstract: This work aimed to study the inheritance of resistance to Phytophthora infestans in tomato plants, using the maximum likelihood estimation function. The susceptible cultivar Santa Clara (Solanum lycopersicum) was used as the female genitor and the P. infestans resistant S. habrochaites f. glabratum accession (BGH 6902) as the male genitor.

10. Direct selection for phenotypic traits in carrot genotypes
RESUMO A seleção de genótipos de cenoura mais produtivos é fundamental para os programas de melhoramento dessa cultura visando aumento na produção com redução dos custos. Assim, objetivou-se com esse trabalho avaliar o ganho com a seleção direta e medir seus efeitos em outras características agronômicas de interesse em cenoura. Para isso, 36 gen�

11. Pure line selection in a heterogeneous soybean cultivar
Abstract Although cultivars of autogamous plants are homogeneous genotypes, they may show natural variability due to mechanical mixing, natural hybridization, and mutation. The aim of the present study was to estimate genetic and phenotypic parameters and to identify and select superior genotypes that associate good performance in traits of interest from a h

12. Selection of conilon coffee clones tolerant to pests and diseases in Minas Gerais
Abstract In the northern Minas region, the dry-warm climate predisposes coffee plants to the occurrence of leaf miners, mites, cercosporiosis, and leaf scald. Aiming for the development of a cultivar adapted to these conditions, Coffea canephora Pierre ex A. Froehner clones were selected through genetic parameters under an irrigated system, without agrochemi
