Multi-trait Multi-environment Qtl Modelling for Drought-stress Adaptation in Maize
Water shortage is a major cause of yield loss in maize. Thus, breeding for adaptation to waterstressed environments is an important task for breeders. The use of quantitative-trait loci (QTL) models in which the response of complex phenotypes under stressed environments is described in direct relation to molecular information can improve the understanding of the genetic causes underlying stress...
متن کاملMaize (Zea mays L.) Response to Nitrogen Fertilizer under Drought Stress at Vegetative and Reproductive Stages
In the sub-tropics, water and nitrogen are the most important factors limiting the grain yield of maize. The effect of nitrogen (N) rates and drought stress at different growth stages of maize were investigated. Nitrogen treatments consisted of 100, 150, and 200 kgN.ha-1 from the urea source while water stress treatments were composed of irrigation-off since the early 10-leaf stage to emergenc...
متن کاملMaize (Zea mays L.).
Agrobacterium tumefaciens-mediated transformation is an effective method for introducing genes into maize. In this chapter, we describe a detailed protocol for genetic transformation of the maize genotype Hi II. Our starting plant material is immature embryos cocultivated with an Agrobacterium strain carrying a standard binary vector. In addition to step-by-step laboratory transformation proced...
متن کاملEvaluation of oxidative stress tolerance in maize (Zea mays L.) seedlings in response to drought.
Seedlings of selected six genotypes of maize (Zea mays L.) differing in their drought sensitivity (LM5 and Parkash drought-tolerant and PMH2, JH3459, Paras and LM14 as drought-sensitive) were exposed to 72 h drought stress at two leaf stage. Alterations in their antioxidant pools combined with activities of enzymes involved in defense against oxidative stress were investigated in leaves. Activi...
متن کاملGenomic Regions Associated with Root Traits under Drought Stress in Tropical Maize (Zea mays L.)
An association mapping panel, named as CIMMYT Asia association mapping (CAAM) panel, involving 396 diverse tropical maize lines were phenotyped for various structural and functional traits of roots under drought and well-watered conditions. The experiment was conducted during Kharif (summer-rainy) season of 2012 and 2013 in root phenotyping facility at CIMMYT-Hyderabad, India. The CAAM panel wa...
