Development and Evaluation in an Opaque-2 Maize Composite at Three Plant Population Densities1
- B. N. Singh and
- Joginder Singh2
Biparental progenies (NC Design-l) were developed an opaque-2 composite of maize (Zea mays L.) at 25,000, 50,000 and 100,000 plants ha-1. They were evaluated at each of these three densities to determine the most appropriate density for development and testing to maximize grain yield. Maximum grain yield, moisture content, plant height, and ear height were observed with hybridization and testing at 100,000 plants ha1- Hybridization at the lowest density with progeny testing at the highest density gave the lowest yield. Irrespective of the level of evaluation, the progenies developed at 100,000 plants ha1-were superior to those developed at the lower population density.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
