“…CDC Frontier typically initiated abortive flower buds at nodes 16 to 20 prior to the formation of perfect flowers regardless of photoperiod, but the number of abortive buds was greater under SD. We observed that F1 populations derived from ICCV 96029 crosses were entirely late flowering under SD, whereas early flowering was recessive in the F2 populations derived from a range of crosses involving ICCV 96029 in our breeding program, consistent with previous reports of recessive earlyflowering phenotypes in segregating populations derived from ICCV 96029 (Gumber and Sarvjeet, 1996;Or et al, 1999;Kumar and van Rheenen, 2000;Anbessa et al, 2006).…”

In climates that experience short growing seasons due to drought, heat, or end-of-season frost, early flowering is a highly desirable trait for chickpea (Cicer arietinum). In this study, we mapped, sequenced, and characterized Early flowering1 (Efl1), an ortholog of Arabidopsis (Arabidopsis thaliana) EARLY FLOWERING3 (ELF3) that confers early flowering in chickpea. In a recombinant inbred line population derived from a cross between CDC Frontier and ICCV 96029, this gene was mapped to the site of a quantitative trait locus on Ca5 that explained 59% of flowering time variation under short days. Sequencing of ELF3 in ICCV 96029 revealed an 11-bp deletion in the first exon that was predicted to result in a premature stop codon. The effect of this mutation was tested by transgenic complementation in the Arabidopsis elf3-1 mutant, with the CDC Frontier form of CaELF3a partially complementing elf3-1 while the ICCV 96029 form had no effect on flowering time. While induction of FLOWERING LOCUS T homologs was very early in ICCV 96029, an analysis of circadian clock function failed to show any clear loss of rhythm in the expression of clock genes in ICCV 96029 grown under continuous light, suggesting redundancy with other ELF3 homologs or possibly an alternative mode of action for this gene in chickpea. The 11-bp deletion was associated with early flowering in global chickpea germplasm but was not widely distributed, indicating that this mutation arose relatively recently.

“…Dias para florescimento em grão de bico é um dos maiores componentes da adaptação ambiental, particularmente quando a estação de cultivo é restringida por fatores climáticos como estresse hídrico e altas temperaturas (Or et al, 1999). Essa característica é também influenciada pela estação de cultivo, latitude, altitude, foto-período e temperatura (Anbessa et al, 2006). Em outras avaliações de genótipos de grão de bico conduzidas sob 12/18 horas de regime de luz mostraram variações entre 27 e 43 dias para florescimento (Anbessa et al, 2006), revelando grande diversidade entre os genótipos avaliados.…”

RESUMOO presente trabalho teve o objetivo de estimar o potencial de cultivo de grão de bico quando submetido a regime de baixa umidade no solo (sequeiro) e identificar genótipos com melhores características morfoagronômicas e de rendimento. O experimento foi conduzido em Brasília-DF em três épocas de semeadura (20/01, 01/03 e 21/03), onde foram avaliados quinze genótipos, incluindo duas cultivares comerciais desenvolvidas no Brasil (Cícero e IAC-Marrocos) e 13 acessos. Durante a condução dos ensaios não foi feito uso de irrigação. Os caracteres avaliados foram número de dias para o florescimento, altura de plantas, número de dias para maturação, arquitetura de plantas, índice de colheita, peso de 1000 sementes e rendimento. Houve interação significativa da época de plantio com os genótipos avaliados para a maioria das variáveis analisadas. Os resultados revelaram que os genótipos FLIP03-109C, FLIP02-23C, FLIP03-34C e Jamu 96 foram superiores às cultivares comerciais cultivadas no Brasil. Esses acessos apresentam um conjunto de características morfoagronômicas desejáveis, podendo ser empregados como parentais em programas de melhoramento genético da cultura ou indicados como opções para novos testes de competições de cultivares visando o cultivo de sequeiro nas condições agroecológicas do Cerrado. Palavras-chave:Cicer arietinum L., cultivares, estresses abióticos, tolerância à seca Evaluation of chickpea genotypes under rain-fed conditions in the Brazilian 'Cerrado' region ABSTRACTThis study aimed to estimate the potential of chickpea cultivation when subjected to low soil moisture conditions and to identify genotypes with better agronomic and yield characteristics. The experiment was carried out in Brasilia in three sowing dates. Fifteen genotypes were evaluated, including two commercial cultivars (Cicero and IAC-Marrocos) developed in Brazil. During the experiment no irrigation was used. The following traits were evaluated: number of days to flowering, plant height, number of days to maturity, plant architecture, harvest index, weight of 1000 seeds and yield. Significant interaction between sowing dates and genotypes was observed for the major parameters. The genotypes FLIP03-109C, FLIP02-23C, FLIP03-34C and Jamu 96 were superior to the commercial cultivars grown in Brazil. These genotypes displayed a set of desirable agronomic characteristics and may be employed as parental in the breeding programs. In addition, they may be indicated as options for cultivation on Savanah conditions.

“…A greater action of the additive genetic effects was evidenced in the traits mean weight of seeds and total number of pods per plant. The understanding of the relative contributions of the genetic and environmental components in variance control of interest traits is a crucial aspect of breeding programs (Anbessa et al, 2006).…”

The objectives of this study were to examine the genetic control of survival in segregant families F 3 of the common bean (Phaseolus vulgaris L.) in southern Brazil during the 2004-2005 growing season, to identify useful genotypes for the breeding program of this crop, and to determine the genetic association between survival and weight of 100 seeds (production trait; P100). A Bayesian approach was used to predict breeding values and to estimate variance components. Survival was recorded as a binary response: dead plant or live plant during harvest. The total population consisted of 11 520 individual plants. The difference in the magnitude between the best and the worst families was as high as 22%, and varied from 57 to 73%. Survival was found to be highly heritable, with an a posteriori heritability mean and Bayesian credible interval: H 2 = 53% (43-65%). The genetic advance by direct selection achieved a value of 18%, considering a selection intensity of 25%. Survival was not correlated with P100 (Pearson = 0.099; Spearman = 0.074), indicating that selection for this trait alone would have little impact on production from a breeding viewpoint. Bayesian analysis, using the Gibbs algorithm, was useful in the genetic evaluation of common bean families based on a binary response variable.
