Diallel analyses and estimation of genetic parameters of hot pepper (Capsicum chinense Jacq.) Scientia Agricola
Sousa,João Alencar de; Maluf,Wilson Roberto.
The degree of heterosis in the genus Capsicum spp. is considered high; however, most of the studies refer to the species Capsicum annuum L. In spite of the potential use of F1 hybrids in pungent peppers of the species Capsicum chinense, few studies are available which assess the magnitude of heterosis in this species . This study was carried out to assess heterosis and its components in F1 hybrids from a diallel cross between hot pepper lines (Capsicum chinense) and to obtain data on the allelic interaction between the parents involved in the crosses. Trials were made in Rio Branco-Acre, Brazil, from March through October 1997. A randomized complete block design with fifteen treatments and three replications was used. The treatments were five C. chinense...

Diallel analysis and heterosis components in paprika peppers Rev. Ciênc. Agron.
Lasmar,André; Maluf,Wilson Roberto; Ticona-Benavente,César Augusto; Nogueira,Douglas William; Nogueira,Danilo Gustavo.
ABSTRACT The aim of this study was to quantify and assess the components of heterosis in paprika hybrids related to yield, capsanten pigment content (estimated as ASTA degrees) and resistance to Phytophthora capsici, and to identify parental lines with high general combining ability (GCA) to be used in future breeding programmes and/or to obtain new hybrids. Fifteen hybrids were obtained through a complete diallel cross (reciprocal hybrids excluded) among six proprietary paprika breeding lines from HortiAgro Sementes S.A., four of which originally introduced from Peru (P1=PIM 032-03; P2=PIM 033-11; P3=PIM 034-19; P4=PIM 035-01) and two from the U.S.A. (P5=PIM 036-08; P6=PIM 037-18). Epistatic gene action was involved in the expression of heterosis for...

Hot pepper (Capsicum chinense, Jacq.) inheritance of reaction to powdery mildew Scientia Agricola
Blat,Sally Ferreira; Costa,Cyro Paulino da; Vencovsky,Roland; Sala,Fernando Cesar.
The pepper species C. chinense has been considered one of the most important resistance sources to powdery mildew Capsicum spp. However, the inheritance in this species was unknown. The purpose of this work was to study its reaction inheritance. Two powdery mildew resistant parents, 'Pimenta Cheiro' 1 and PI 152225 and two moderately susceptible ones, 'Pimenta Doce' IH-1761 and 'Pimenta Índio', were used to obtain three F1 and their respective F2 generations: 'Pimenta Doce' IH-1761 <FONT FACE=Symbol>´</FONT> 'Pimenta Cheiro' 1, 'Pimenta Índio' <FONT FACE=Symbol>´</FONT> PI 152225 and 'Pimenta Doce' IH-1761 <FONT FACE=Symbol>´</FONT> PI 152225. The powdery mildew epidemy was natural using inoculum from a...

Inheritance of reaction to Leveillula taurica (Lev.) Arn. in Capsicum annuum L. Scientia Agricola
Blat,Sally Ferreira; Costa,Cyro Paulino da; Vencovsky,Roland; Sala,Fernando Cesar.
The use of fungicides to control powdery mildew in sweet pepper has been ineffective and genetic resistance is the best alternative. Resistance sources identified in Capsicum annuum L. are rare and unsatisfactory. The purpose of this work was to study the inheritance of C. annuum reaction to powdery mildew. Three homozygous powdery mildew resistant parents, HV-12, Chilli and #124 and three susceptible lines, 609, 442 and 428 were used to obtain seven F1's and respectively their generations F2: HV-12 x 609, 442 × HV-12, 428 × HV-12, Chilli × 609, #124 × 609, Chilli × HV-12 and #124 × HV-12. The powdery epidemic was natural using inoculum from highly sporulating susceptible pepper host. Powdery mildew host reaction evaluations were carried out during the...
