Adaptability and stability of early carioca beans by mixed models
Lima, Thalyson Vasconcelos; Santos, Paulo Ricardo dos; Oliveira, Tâmara Rebecca Albuquerque de; Nascimento, Maxwel RodriguesThe genotype x environment interaction represents one of the major selection challenges due to the difficulty in identifying effectively superior genotypes. The present study aimed at estimating genetic parameters and selecting genotypes of early Carioca beans by analyzing simultaneous attributes, including yield, adaptability, and stability. In the agricultural year of 2015 and 2016, three trials were conducte...
Progeny coriander resistant root-knot nematode
Santos, Ana Maria Maciel dos; Costa, Kleyton Danilo da Silva; Oliveira, Tâmara Rebecca Albuquerque; Silva, José Wilson da; Souza, Ênio Gomes FlôrCoriander is a important vegetable crop in Brazil, being widely consumed as a condiment and cultivated mainly in North and Northeast brasilian regions. Diseases caused by Meloidogyne species are one main causers damages of crop. In the literature there is no reported about identification nematoid resistant coriander genotypes. In this study was carried the reaction evaluation of a heat-tolerant coriander popula...
Seleção de descritores em cana-de-açúcar por meio de componentes principais
Costa, Kleyton Danilo da Silva; Carvalho, Islan Diego Espindula de; Santos, Lucas da Silva; Santos, Paulo Ricardo dos; Silva, José Wilson daForam avaliados oito caracteres agronômicos com o objetivo de selecionar os melhores para caracterizar os clones. Utilizou-se a análise de componentes principais objetivando o descarte de descritores considerados redundantes ou não discriminantes. Este método permitiu redução de quatro dos oito descritores agronômicos, do conjunto inicialmente considerado. Foi possível selecionar, por intermédio desta técnica, ...
Correlações fenotípicas entre caracteres de parte aérea e raiz em famílias de m...
Silva Costa, Kleyton Danilo da; Carvalho, Islan Diego Espindula de; Santos, Paulo Ricardo dos; Silva, José Wilson da; Santos, Lucas da SilvaO estudo teve o objetivo de estimar as correlações fenotípicas entre seis caracteres de cenoura de interesse agronômico e fazer uso da seleção indireta para escolher as melhores progênies. Foi utilizado o delineamento em blocos casualizados, constituído de 25 progênies de meios-irmãos de cenoura com quatro repetições, oriundas do composto UFAL – 1, obtido a partir do intercruzamento entre as seguintes cultivar...
Path analysis in characters of yield of sweet potato clones (Ipomoea batatas (L...
Cavalcante, Jair Tenório; Ferreira, Paulo Vanderlei; Soares, Lailton; Borges, Vanderley; Silva, Paulo Pedro da; Silva, José Wilson daThe sweet potato (Ipomoea batatas (L.) Lam) is a tuberous vegetable of large adaptation, cultivated in all Brazilian regions that is used for human being or animal feeding. In Brazil, it is cultivated 43,900 ha with an average yield of 11.035 kg ha-1. Despite the importance of this crop to Brazilian agriculture very little is known about the factors involved in the production of commercial roots. The objective ...
Canonical correlations of agro-industrial characteristics in sugarcane - DOI: 1...
Silva, José Wilson da; Soares, Lailton; Ferreira, Paulo Vanderlei; Silva, Paulo Pedro da; Silva, Maria José Cavalcante daThe analysis of canonical correlations measures the existence and the intensity of the association between two groups of variables or characters of importance. This study aimed to estimate the intensity in the association between the agronomic and industrial characters in sugarcane. The analysis of canonic correlations allowed to conclude that clones with bigger number of stalks per parcel, greater number of st...
