Plants of all tomato genotypes were selfed for two generation before crossing, and the following crosses were made between the resistant parent (NCEBR-6) and the other five domestic genotypes to produce four populations as the following:1- (Edkawi × NCEBR-6), 2- (UCT5 × NCEBR-6), 3- (Super strain-B × NCEBR-6) and 4- (Peto-82 × NCEBR-6). Seeds of F1 and its parent were germinated separately under greenhouse in trays containing mixture peatmoss and vermiculite. Crosses and their parents were transplanted on the 20th of October under plastic greenhouse and11th of October 2009 into the field and repeated transplanted on 24 November 2009, season 2009-2010 under greenhouses. The experimental were designed in a randomized complete block design with four replications. Minimum and Maximum temperature degrees with relative humidity, wind speed and solar radiation were recorded daily for seven months, form October,2008 to May2009 as well as 2010. The average metrological values for the different previously mentioned measurements were obtained from Maryout climate Station are illustrated in Table 2 1 The metrological data of Maryout climate station during the growing 2008/2009 - 2009/2010 and presented in Table 2
