The aim of this study was to use multivariate methods and Pearson and partial correlations to disregard phenotypic characteristics that contribute little to differentiation between Brachiaria ruziziensis genotypes. Eighty-one genotypes of B. ruziziensis were assessed in completely randomized blocks with three replications. Ten phenotypic characteristics were assessed: plant height, leaf length,...

Abstract Flower shape is a key trait of ornamental and commercial importance in breeding programs for chrysanthemum ( Chrysanthemum morifolium Ramat.). Understanding the genetic basis phenotypic variation seen inflorescence-related traits will contribute to improvement development new varieties. In this study, we investigated determinants inflorescence using an F 1 segregating population derive...

Boreal tree species are excellent tools for studying tolerance to climate change. Bud phenology is a trait, which is highly sensitive to environmental fluctuations and thus useful for climate change investigations. However, experimental studies of bud phenology under simulated climate change outdoors are deficient. We conducted a multifactorial field experiment with single (T, UVA, UVB) and com...

OBJECTIVE To compare the effectiveness of budesonide/formoterol using fixed dosing (BUD/FORM) with inhaled corticosteroid (ICS) alone or alternative ICS and long-acting beta(2)-agonist (LABA) regimens for adults with moderate/severe asthma. METHODS BIOSIS, CENTRAL, EMBASE and MEDLINE were searched for abstracts and papers. All searching was completed in July 2006. No restriction was placed on...

The electronic form of this issue, available as of March 6, 2013, at www.plantphysiol.org, is considered the journal of record. On the Cover: Brachypodium (Brachypodium distachyon), or purple false brome, is a member of the grass subfamily Pooideae, which also includes two of the world’s economically important crop species, wheat (Triticum aestivum) and barley (Hordeum vulgare). This small and ...

The number of pods per common bean plant is a primary component of grain yield, which depends on the number of flowers produced and on the flower set. Thus, a larger number of flowers per plant would increase yield. Lines with inflorescences that had a large number of flowers compared to common bean plants now under cultivation were identified. We analyzed the genetic control of this trait and ...

Maize (Zea mays ssp. mays) and its wild progenitor, teosinte (Z. mays ssp. parviglumis) differ dramatically in inflorescence and plant architecture despite the fact that their evolutionary divergence occurred within the past 10,000 years or less. To elucidate the genetic control of the morphological differences between maize and teosinte, my colleague and I employed quantitative trait locus map...

Objective: To explore the effect of altitude and latitude on breeding of Amomum tsaoko Crevost et Lemaire, a flexistylous ginger, which fruit is used as common materia medica and a food condiment. Methods: The 7 populations were selected randomly from the three floristic zones of Yunnan. Adult plants and infructescences were chosen randomly to gain flower number and fructification percentage pe...
