Analysis of the contraints of tomato

Semi-structured questionnaires were administered to 64 respondents comprising 30 farmers, 24 retailers and 10 wholesalers. The data were collected in in Pwalugu, a major tomato growing area in the Upper East Region of Ghana.

The objective of this study was to determine whether combining resistance derived from different sources would result in F1 progenies with resistance greater than that of the parents.

Five bacterial wilt-resistant tomato lines or accessions CL, L, CRA84, H, and GAeach derived from different resistance sources, and a susceptible processing tomato line UCA were crossed in all combinations without reciprocals.

Parents, F1 progenies, and F2 progenies were evaluated in greenhouses at three locations Taiwan, Philippines, and Indonesia for percent survival 6 weeks after drench inoculation with virulent local strains of R.

Percent survival means over locations were Positive GCA effects over locations were detected for H, CRA84, and L, indicating that progeny with those lines as parents showed bacterial wilt resistance that was greater than the average of all crosses.

Only H, however, had positive GCA effects estimates at each location for each generation, and its GCA effects estimates over locations were significantly greater than those of the other parents in the F1 and F2 progenies.

Among this set of parents, H is the best source to develop bacterial wilt-resistant progeny. We did not observe statistically significant increases in resistance by combining different resistance sources. However, the presence of large GCA variances suggests that hybridization of parents that have high GCA for bacterial wilt resistance, such as H, CRA84, or L, followed by selection in segregating populations might yield inbred progeny with resistance greater than that of the parents.A genetic functional analysis of AtMYST6 shows that the MYST6 protein is required for root hair development and over-expression of AtMYST6 increases root growth and alters root system architecture, overcoming constraints on normal root growth.

Keywords: tomato harvest, agricultural ergonomics 1. Introduction Agricultural work presents grounded by a universe of constant variability and uncertainty, which leads workers to develop strategies as a leeway to overcome the constraints arising from their work practice (Montedo and Sznelwar, ).

Jul 27,  · The understanding of these constraints and their concomitant factors that influence such constraints are very useful in policy implementation towards the advancement of farmers’ adaptive capacities to increase tomato production.
