1. Combining abilities analysis for ear rot resistance in popcorn hybrids development
ABSTRACT Ear rot caused by fungi of genus Fusarium (FER) is one of the potentially harmful diseases to grain quality in maize. Given the capacity to produce mycotoxins, FER presents a risk to food safety. This study sought to identify parents and indicate hybrids of popcorn with a higher level of resistance to the incidence and severity of FER. Hybrids were

2. Potential of pepper plant accessions for ornamental purposes using diallel analysis
Abstract: The genus Capsicum is cultivated in various parts of the world, with C. annuum showing high diversity and potential for ornamental purposes and genetic improvement. The aim of this work was to evaluate the combining ability and heterosis of seedling and plant traits in accessions of ornamental pepper and their hybrids. Seven accessions of C. annuum

4. Combining capacity and heterosis in eggplant hybrids under high temperatures
RESUMO Este trabalho teve como objetivo estimar a capacidade combinatória e a heterose de híbridos de berinjela em condições de altas temperaturas. Foram avaliados sete genitores, doze combinações híbridas oriundas de um dialelo parcial e o híbrido Ciça F1 como testemunha. O experimento foi conduzido em casa de vegetação, no delineamento experimen

5. Genotype x environment interaction analysis of multi-environment wheat trials in India using AMMI and GGE biplot models
Abstract Fifty wheat genotypes were evaluated at nine diverse locations in India to identify high-yielding and stable genotypes. The analysis of variance based on additive main effects and multiplicative interaction (AMMI) indicated significant genotype, environment and genotype - environment (GE) interactions, with a total variation of 5.99, 20.23 and 73.77

6. Genetic parameters and selection of sugarcane in early selection stages for resistance to sugarcane borer Diatraea saccharalis
Abstract A T1 (sugarcane population originating from true seeds) and T2 (first sugarcane clonal stage) population were used to estimate genetic parameters and compare selection strategies for Diatraea saccharalis (Lepidoptera: Crambidae) resistance in sugarcane. In the T1 stage, heritability at the family mean level (h²=0.77) was higher than individual geno

7. Combined effects of water status and iron deficiency chlorosis on grape composition in non-irrigated vineyards
ABSTRACT: Although water deficit and iron deficiency chlorosis are common environmental stresses in the Mediterranean area, few data are reported in the literature on their effects on vineyards, when acting simultaneously. The main objective of this research was to study the combined effects of iron deficiency and water status on vigor, yield and fruit compo

9. The topical treatment of old world cutaneous leishmaniasis with gentian violet along with cryotherapy: a pilot single-blind randomized controlled clinical trial
Abstract INTRODUCTION: The promising non-clinical antileishmanial effects of gentian violet (GV) encouraged us to evaluate the additive effect of GV on cryotherapy. METHODS: For 8 weeks, 59/161 cutaneous leishmaniasis patients/lesions underwent cryotherapy alone (group 1) or cryotherapy accompanied by 1% GV application (group 2). The primary endpoint was

10. Genetic variability in popcorn synthetic population
ABSTRACT. The Brazilian popcorn has low genetic variability and the successful development of advanced lines, new popcorn cultivars with high grain yield (GY) and expansion volume (PE) is dependent on parental selection and precise determination of heterotic groups. The aim of this study was to evaluate genetic variability and identify heterotic groups in sy

11. The combining ability of popcorn S7 lines for Puccinia polysora resistance purposes
ABSTRACT The present study resulted from the lack of information on the genotypic expression ruling the resistance to rust and on the main traits of economic importance to the herein addressed crop. The combining ability of 16 popcorn lines and hybrids was assessed in partial diallel cross in two representative locations in Rio de Janeiro State, Brazil, wher

12. Potential of soybean crosses in early inbreeding generations for grain yield
Abstract The present study aimed to evaluate the combining ability of 16 soybean genotypes using a partial diallel. Two experiments were carried out to estimate the general (GCA) and specific (SCA) combining ability, one with 64 crosses and the other with 16 parents. At the R8 stage, F2 plants and the parents were evaluated for the following traits: number o
