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

Abstract

This study was conducted evaluation to the genetic parameters for sevengenotypes of tomato.( Lycopersicun esculentum.Mill) are: (local, Polaris,SG112, Sumaya, Red Rock, Sun, Mercar) under the effect of three types offertilizers 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 offertilizer in the yield characters of quantitative and qualitative. and some geneticparameters .The results of the variance analysis showed significant differences between themean for all varieties squares studied characters and the superiority of theproduct Mercar genotype plant gave the being of 4.788 kg / plant, andsignificant effect between the types of fertilizers for all characters except forfirmness and total acidity.As the interaction between genotype and types of fertilizers no significanteffect for all characters and yield highest per plant was 7.348 kg / plant whenthe interaction with poultry manure cultivar Mercar.The broad sense heritability was high for all characters except (TSS), whichwas medium. It also showed the genetic variation and phenotypic differencesignificant for all characters except (TSS) of the genetic variation, while thedifferences did not significant for environmental variation for all characters .The percentage of genetic improvement was expected for the high qualities ofthe average fruit weight and number of fruits and ratio of soluble solids TSS andthe degree of firmness and the average for the rest of characters. It was not thegenetic correlation between moral qualities while the link environmental andpositive treatment effect between the number of fruits and yield of plant andbetter correlation phenotypic was negative and significant treatment effectbetween the number of fruits and average fruit weight .
