EFFECT OF FERTILIZER TYPE ON QUANTITATIVE AND QUALITATIVE YIELD CHARACTERS OF TOMATO ( Lycopersecun esclantum Mill.) AND SOME ESTIMATE GENETIC PARAMETERS .

Abstract

This study was conducted  evaluation to the genetic parameters for seven genotypes of tomato.( Lycopersicun  esculentum.Mill)  are: (local, Polaris, SG112, Sumaya, Red Rock, Sun, Mercar) under the effect of three types of fertilizers are: (poultry manure, Alheiomk compounds, chemical fertilizers) in Diyala governorate  during the 2012 spring planting season, according to Strip- Plot Design with three replications to study the genotype  effect and types of fertilizer in the yield characters of quantitative and qualitative. and some genetic  parameters . The results of the variance analysis  showed significant differences between the mean for all varieties squares studied characters and the superiority of the product Mercar genotype plant gave the being of 4.788 kg / plant, and significant effect between the types of fertilizers for all  characters except for  firmness and total  acidity.  As the interaction  between genotype  and types of fertilizers no  significant effect for all characters  and yield highest per plant was 7.348 kg / plant when  the interaction with poultry manure cultivar Mercar. The broad sense heritability was high for all   characters  except (TSS), which was medium. It also showed the genetic variation and phenotypic difference significant  for all characters except (TSS) of the genetic variation, while the differences did not significant  for environmental variation for all  characters . The percentage of genetic improvement was expected for the high qualities of the average fruit weight and number of fruits and ratio of soluble solids TSS and the degree of firmness and the average for the rest of characters. It was not the genetic correlation between moral qualities while the link environmental and positive treatment effect between the number of fruits and yield of  plant and better correlation phenotypic  was negative and significant treatment effect  between the number of fruits and average fruit weight .
