Abstract. Suwarti, Ghulamahdi M, Sopandie D, Trikoesoemaningtyas, Sulistyono E, Azrai M. 2022. Secondary trait and index selection determination for maize genotype in acidic tidal swamp environment. Biodiversitas 23: 4169-4179. Determining secondary traits as complementary genotypes abiotic stress environment is compulsory since yield-based usually provides biased result. This study aimed to obtain an multi-stresses of Fe, Al, temporary flooding environments acid sulfate land using multivariate analysis. A total 150 (un-repeated) inbred lines five check replicates were arranged a randomized augmented plot design three generate 525 single plots. Three types based on irrigation regimes applied soil the agronomic characteristics each Saturated Cultivation Technology (SSC) was considered optimal Dryland treatment condition let only depend rainwater. Temporary carried out at stages different growth periods. Several steps analysis this by taking variance, heritability used basis selections. The characters affected treatments with medium high then analyzed correlation pathway Seven indexes, SSI, GMP, YSI, YI, TOL, STI, MP, that have yield both optimum environments, simultaneity selected screen utilizing PCA biplot Venn group result Indices rows number per ear weight 6 ears Soil culture stress.

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...

Background: Today factors including cultural, social, religious, economic and medical such as X Linked diseases encouraged couples to choose traditional methods or new treatment for selecting the gender of child. It seems that Spermatozoa containing chromosomes X and Y have different speed in various pH. In this study the velocity of spermatozoa in different acidic pH was evaluated. Materials a...
متن کاملSelection of Barley Superior Lines with Desirable Agronomic Characteristics Using the Selection Index of Ideal Genotype (SIIG)
This study was conducted to investigate the phenotypic diversity of 108 pure barley lines in Augment design with four controls in six blocks in the farm of Darab Agricultural Research Station (2020-2021). In order to select the best lines in terms of yield and other traits, SIIG index was used. The results of restricted maximum likelihood (REML) analysis showed that the lowest and highest level...
