The present investigation entitled “Line X Tester analysis in Tomato (Lycopersicon esculentum Mill.)” was undertaken at Main Experiment Station, Department of Vegetable Science of Narendra Deva University of Agriculture & Technology, Narendra Nagar, Kumarganj, Faizabad (U.P.). Analysis of variance revealed significance differences among the genotype for all the characters indicating existence of wide variation in the experimental material evaluated. The analysis of variance of present investigation having 14 parents and 40 hybrids for 14 characters was carried out and mean squares obtained. The anylysis of variance for combining ability revealed significance difference due to lines, testers and line x tester interection for all the traits. The indicated that combining ability played vital role in the expression of the traits under study.

The Mean

Tomato (Lycopersicon esculentum Mill.) is major fruity vegetables grown in Ethiopia next to hot pepper. Although crops grown in the country its production and productivity is very low compared to the world average. Among the reasons for low its production and productivity, shortage of improved tomato varieties is the major one.  This experiment was done with the aim of evaluating tomato varieties and select high yielding cultivars. An experiment was conducted in bonga district Gambella region 2011/12 dry season under irrigated condition. Seven tomato varieties namely ARP Tomato D2, Fetan, Melkasalsa, Chali, Bishola, Gelila and  Roma-VF(as local check) and  were tested in randomized complete block design with 3 replications. The mean values of all parameters were subjected to two way analysis of variance using the Proc GLM procedure of  SAS 9.3. Then statistical significance of the mean of each parameter was determined using F-test and Duncan multiple range test procedure was used to compare differences between treatment means at 5% probability level. The analysis of variance showed statistically significant differences (p< 0.05) among varieties in all growth and yield parameters except days to 50% flowering. Among the tested tomato cultivars, Melkasalsa produced the largest fruit. The highest fruit yield was recorded by Melkasalsa followed by Bishola. we can conclude Melkasalsa and Bishola variety were the most productive and gave larger fruit compared to others. Hence, these varieties can be used by tomato growers under irrigated condition around Bonga area.
