Relationship between Seed Properties and Outcome Components for Selection Criteria of Corn (Zea Mays L.) Products at Various Dosages of Popostium Fertilizer

This research was conducted to determine the relationship between seed developmental characteristics and yield components in a population of maize (Zea mays L.) grown at different potassium fertilizer rates. The information could be utilized as alternative selection criteria for genotypes with high-yielding potential. Experimental field Horticulture Seed Agency, Pekanbaru. Seven four rates were 350 cm x 200 experimental plot three replications. used Bisi 228. Pertiwi 3. 2. Decoral, 18. Betras 4. Srikandi. Potassium included 30 kg, 50 70 90 kg per ha, respectively. Traits observed plant height, tesseling flowering date, silking dry accumulation rate, effective filling period, cob length, weight, number rows, seeds cob, weight 100 m2. Analysis variance performed data using SAS further tested by honesty significant difference 5% level. Variance component, heritability, genetic correlation coefficient, response calculated all characters duration. results indicated that component except matter rate. All characters' heritability values quite high seed-filling duration cob. Phenotypic coefficients positively m2 development ear ear, seeds. correlations ear. direct value is higher than indirect value.
