Combining ability studies on resistance to pink stem borer (Sesamia cretica) in new yellow maize (Zea mays) hybrids

COMBINING ABILITY AND HETEROSIS IN MAIZE (Zea mays L.)

A line × tester analysis was conducted in maize involving 12 lines and 3 testers for grain yield and its components to determine the heterosis as well as general combining ability (GCA) and specific combining ability (SCA) effects. Highly significant genotypic differences were observed indicated wide range of variability present among the genotypes. GCA and SCA variance for yield per plant numb...

T Evaluation of genes effect and combining ability in selected maize (Zea mays L.) lines

Maize is one of the most important grain and forage plants that has a unique role in the food and feed, especially poultry feed. To study the genetic effects, genes act and identify the best hybrid combination for morphological traits, experiment was carried out in diallel cross layout using 19 parents at Gorgan Agricultural Research Station, Iran in 2013. The progenies were planted in three re...

Evaluation of genes effect and combining ability in selected maize (Zea mays L.) lines

To evaluate radiation use efficiency and weed control, this experiment was conducted in two locations in Ahwaz, Iran, in a randomized complete block design with 14 treatments and four replications in 2016-2017. Treatments included: Sole sugarcane, Sole soybean, Sole cowpea, Sole soybean+rhizobium, Sole cowpea+rhizobium, Sole sugarcane+mycorrhizal, Intercropping sugarcane with cowpea, Intercropp...

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...
