1. Diallel analysis of popcorn populations for yield, popping expansion and resistance to fall armyworm
ABSTRACT The objective of this study was to estimate the varietal and heterotic effects related to grain yield, popping expansion and resistance of popcorn against fall armyworm. Twelve open-pollinated varieties were intercrossed in a complete diallel mating scheme. The 66 experimental hybrids, together with their parents and controls Zapalote Chico, BRS 103

2. Uni and multivariate approaches for diallel analysis in early generation trials for soybean tolerance to rust
ABSTRACT Due to the high impact of Asian soybean rust (SBR) in Brazilian croplands, several studies have been conducted in order to maintain or increase the grain yield gain over years in the presence of the pathogen. The aim of this study was to define a breeding strategy applying uni and multivariate approaches for diallel analyzes in early generation tria

3. 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

5. Identification of populations and hybrid combinations of maize for in natura consumption
ABSTRACT Brazil is one of the leading countries in the production of maize (Zea mays), with great potential for growing green maize, which has a superior commercial value in relation to maize marketed in the form of grains. Although important, the availability of cultivars recommended for the production of green maizeis still very scarce. The objectives of t

6. 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

7. Combining Ability for Resistance to White Mold in a Diallel Cross of Soybean
Abstract The white mold, caused by Sclerotinia sclerotiorum (Lib.) de Bary, is one of the most important diseases of soybean. The objective of the present work was to evaluate the soybean reaction to the fungus S. sclerotiorum, which causes white mold, in a partial diallel with 50 crosses. The Group I of parents was composed of ten experimental lines with hi

8. Selection of parents for low nitrogen stress through the combining ability of maize partially inbred lines
ABSTRACT. The objective of this work was to estimate the general combining ability of partially inbred lines under high and low nitrogen (N) conditions and to select promising lines to obtain high yields for both conditions. Fifty-five partially inbred S1 progenies were evaluated using the top-cross method, where the lines were crossed with two testers. The

9. Estimation of genetic merit of diallel hybrids of sweet pepper by mixed models
RESUMO: A utilização de modelos mistos na avaliação de cruzamentos dialélicos é uma opção altamente oportuna para a fidedigna predição dos valores genéticos das progênies. Na cultura do pimentão, os híbridos são largamente explorados comercialmente, principalmente por suas características de importância econômica. O objetivo deste trabalho

10. Selection of melon genotypes with resistance to Didymella bryoniae using a diallel approach
ABSTRACT. The development of melon lines resistant to gummy stem blight (GSB) is an important strategy for decreasing losses caused by this disease. Thus, selecting the best parents for such a goal is essential. We evaluated the general (GCA) and specific (SCA) combining abilities of lines and accessions to guide the selection of the most promising parents t
