| dc.description.abstract | Owing to the limited availability of high yielding cultivars that are suitable for different purposes, the yield of tomato in Ghana falls between 7.5 and 10 tones/ha which is far below the world’s average yield 45-50 tones/ha. Therefore, identification of superior plant and fruit types for further improvement in yield is necessary. Hence, two separate experiments designated as genotype (F) and genotype (G) were conducted at the Horticulture Division, Council for Scientific and Industrial Research (CSIR)-Crops Research Institute (CRI) Kwadaso, Kumasi, Ghana to evaluate early generations of interspecific crosses of tomato (Solanum lycopersicum L.) genotypes for yield using a Randomized Complete Block Design with three replications under field conditions. Data were collected on growth parameters and yield components, including plant height, stem girth, days to flowering, days to maturity, fruit weights, number of fruits per plant, fruit length, fruit diameter, fruit flesh thickness, brix, total fruit weight per genotype, marketable fruits and nonmarketable fruits per plant. Heritability was estimated on the above traits. Results from the study showed that total marketable fruits was higher for ‘BC2F1’, ‘F2’, ‘F1’, P2 (213)’, and ‘P2 (042)’ than the rest of the genotypes, whereas P1 (083), P1 (097), BC1F1 had the lowest for total marketable yield. Considering yield and yield components, F2 was found to be better than the rest of the genotypes for most of the characters for genotype (F), while P2 (213) produced higher yield than segregating population for genotypes (G) and F1 was found to be the poorest performer for almost all parameters for genotypes (F) and (G). Fruit flesh thickness, fruit length, fruit diameter and number of nonmarketable showed high broad sense heritability. Number of marketable fruits, total fruit weight, number of fruit per plant, brix, days to flowering, days to maturity, fruit flesh thickness, fruit weight per plant and stem girth showed high heritability. | en_US |
