Selection of High Yield and Stable Maize Hybrids in Mega-Environments of Java Island, Indonesia

چکیده
Determination of grain yields stable and high-yielding maize hybrids in a wide environment requires high accuracy. Many stability measurement methods have been used multi-environment experiments. However, the relationships among different are still difficult to understand. The objectives this study were 1. Identify effect growing season location (Environments = E), (Genotypes G), their interactions (GEIs) on yields; 2. Select range environments; 3. Determine relationship between each estimation; 4. mega-environment hybrid identify best locations for testing. Field experiments conducted at ten Java Island, Indonesia, two seasons using randomized completed block design with three replications. experimental results showed that main effects season, location, hybrid, GEIs, significantly affected yields. Stability estimations TOP, S(3), S(6), NP(2), NP(3), KR, NP(4), CVi, bi, belong concept dynamic can be select favorable environments, while other classified as static stability. Three successfully selected, based numerical visual estimations, namely SC2, SC7, SC9. candidates sustainable development programs. dry rainy combination produced mega-environments. GJRS KARS most discriminative environments. Both environments selecting ideal hybrid.

Genetic improvement of Grain Yield by Determination of Selection Index in Single Cross Hybrids of Maize (Zea mays L.)
Selection based on proper selection indices can be one of the most effective methods for indirect selection of yield and yield components, simultaneously. In order to determination of selection index for improvement of maize yield, 60 single cross maize hybrids were planted in two separate experiments (drought stress and normal conditions) based on randomized complete block design (RCBD) with t...

Extended Abstract Introduction and Objective: Selection of desirable hybrids compared to other maize hybrids (Zea mays L.) is one of the methods used to achieve high grain yield in maize. Also, the most important morphological features affecting grain yield can be used in the selection and introduction of genotypes. Material and Methods: This study was conducted to investigate the relationshi...
