Production of tomato in Ethiopia as well as in Amhara Region is low; this could be due to
lack of high yielding and high quality genotypes. Therefore, the aim of this study was to
evaluate variability and performance of 17 tomato genotypes for growth, yield and quality
at SARC Kobo sub center during the 2021 irrigation season. A field experiment was laid
out in Randomized Complete Block Design (RCBD) with three replications. Analysis of
variance for 21 quantitative traits revealed that there was a highly significant difference
(P<0.01) among the seventeen genotypes for all the characters studied except
unmarketable yield. This indicates the presence of considerable genetic variability for
further improvement of tomato for yield and quality aspects. The difference between PCV
and GCV was relatively small for most of the traits, implying that genotype contributed
more than environment in the expression of the characters. High GCV and PCV was
observed for titratable acidity, average single fruit weight, physiological weight loss, plant
height and number of cluster per plant. High heritability estimates coupled with high
values of genetic advance as percent of mean observed among some traits; indicates that
they were governed by additive gene action and therefore provides the most effective
condition for selection. Metadel, Woyno, Fetan, and Miya tomato genotypes were matured
earlier than the rest of the tested genotypes. Chali (59.62 t/ha), Eshet (51.95 t/ha),
Metadel (51.12 t/ha) and Melka salsa (47.43 t/ha) and tomato genotypes gave better
marketable fruit yield while Chali, Eshet, Gelila, Metadel, Bishola, and ARP D2 Tomato
genotypes had the highest juice content. From the participatory evaluation, Metadel,
Chali, Eshet and Cochiro were selected by the farmers. In terms of marketable yield;
Chali, Eshet, Metadel, and Melka Salsa genotypes can be recommended for the study
area. In terms of fruit quality parameters, the genotypes Chali, Eshet, Gelilal, and
Metadel can be suggested for commercial production and processing industry. However, it
is advisable to repeat the experiment on different agro-ecologies and years with more
number of materials. |
