Maize (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 کاملCO(2) Compensation Concentration in Maize (Zea mays L.) Genotypes.
Heichel and Musgrave (4, 5) reported photosynthetic rates of maize genotypes ranging from 21 to 85 mg CO2 dmhr-' which were inversely associated with similar large differences in CO2 compensation concentration of from 9 to 25 plll. Since genotypic differences of the magnitude reported by Heichel and Musgrave would be of great value in breeding for increased photosynthetic efficiency, we conduct...
متن کاملGenetic Effects Conferring Heat Tolerance in a Cross of Tolerant × Susceptible Maize (Zea mays L.) Genotypes
Incessant rise in ambient temperature is threatening sustainability of maize productions, worldwide. Breeding heat resilient synthetics/hybrids is the most economical tool while lack of knowledge of gene action controlling heat and yield relevant traits in maize is hampering progress in this regard. The current study, therefore, was conducted using analyses of generation mean and variance, and ...
متن کاملGenetic Diversity in Maize (Zea mays L.) Inbred Lines
Thirty yellow inbred lines of normal maize were evaluated for thirteen parameters at the experimental field of Hajee Mohammad Danesh Science and Technology University during 2010-11 to study the genetic divergence using multivariate analysis. The thirty inbreds fell into six distinct clusters. The intra-cluster distances in all the six clusters were more or less low, indicating that the genotyp...
متن کاملGenetic analysis to determine the nature and magnitude of genetic variances and heritability estimates in maize (Zea mays L.)
The F1 hybrids along with the parents were evaluated in field for genetic analysis to determine the nature and magnitude of genetic variances and heritability estimates a in maize (Zea mays L.) in 2012 using RCBD with three replications. Results analysis of variance showed, based upon the results of tests, simple genetic model was fully adequate for analyzing the data set for all traits except ...
