To define breeding strategies, the understanding of trait inheritance is critical. The objective this study was to determine popcorn under different water regimes. end, Hayman’s diallel methodology used, with 8 parents and 28 hybrids. experiment carried out well-watered conditions (WW) stress (WS). For popping expansion (PE) both regimes, effects complete dominance greater importance components associated were observed. In contrast, number dominant genes zero determination coefficient in...
Drought is a common abiotic stress in tropical and subtropical regions that limits the growth development of agricultural crops, mainly impacting grain yield. Acting through plant breeding most viable alternative for obtaining genotypes more tolerant environments with stress.

However, for experiments with ideal availability, sidedressed crop requirement, whereas N-poor sidedressing consisted...
The search for productive germplasm adapted to adverse conditions is an important action mitigate the harmful effects of climate change. aim was identify yield potential 50 popcorn inbred lines grown in field conditions, two crop seasons (CS), and under contrasting water (WC). Morphoagronomic, physiological, root system traits were evaluated. Joint individual analyses variance performed, addition multivariate GT bip-lot analysis. Expressive reductions between WC observed 100-grain weight...
This study aimed to identify the genetic control of morphological, water status, and root traits in four inbred lines their pre-selected hybrid combinations popcorn, best parents hybrids. The plants were grown under greenhouse conditions, with two conditions—water-stressed (WS) well-watered (WW). We evaluated shoot biomass (SB), whole plant leaf area (WPLA), chlorophyll content, carbon isotope discrimination, net CO2 assimilation rate, stomatal conductance, transpiration, cumulative weight...
The UENF WS01 is a hybrid that has an early cycle and high grain yield capacity under low water nitrogen availability. It maintains popping expansion even abiotic stress, thus being recommended for cultivation in the North Northwest of State Rio de Janeiro.

Os analisados quanto ao comprimento, largura, espessura, peso, espessura da casca, o peso polpa, das sementes/fruto, número sementes/fruto teor sólidos solúveis. As avaliadas relação índice volume....
Developing popcorn genotypes that are adapted to water-deficit conditions is crucial due the significant impact of this abiotic stress on grain yield. This study aimed assess combining abilities preselected lines for agronomic and root traits under well-watered water-stressed conditions. A circulating diallel analysis was conducted investigate effects general specific 10 their respective hybrids various traits, including productivity, popping expansion, expanded volume, 100-grain weight, ear...
Ginger (Zingiber officinale Roscoe) is a selfincompatible plant and has high rates of infertility; its genetic diversity only occurs via processes mutation natural selection.Since ginger important as condiment an herbal medicine, understanding to greater degree can contribute both conservation use in breeding programs.Considering the importance species characterization material from on-farm conservation, this study aimed evaluate, by means ISSRs (Inter Simple Sequence Repeats) molecular...
O gengibre (Zingiber officinale Roscoe) é uma planta utilizada como condimento e fitoterápico. A utilização fitoterápico segue o conhecimento tradicional, a sabedoria popular, um patrimônio cultural ser preservado. Este estudo teve por objetivo realizar levantamento quanto do familiares de alunos duas unidades escolares Alta Floresta, MT. Informações socioeconômicas relativas à foram obtidas meio entrevista estruturada semiestruturada observação participativa. Os resultados avaliados...
