SCREENING OF TOMATO ACCESSIONS FOR RESISTANCE TO ...

The'result of the effect of Fusarium wilt on agronomic and yield parameters of the
tomato accessions are presented in Table 2, 3, and 4. The number of branches, plant height and
number of leaves per plant recorded in this study were as a result of their genetic resistance. The
resistant accessions maintained their leaf numb~rs despite the Fusarium,wilt.
Based on the number of leaves and plant height on Table (3), NG/MRIMA Y/09/005
has 53.68cm for Strain 1 and 51.78cm for strain 2 while NG/MRIMAY/09l006
has 54.88cm for
strain 1 and 65.89cm for strain 2 and are more resistant to both strains of Fusarium inoculated and
the accession that recorded the highest number of the leaves/plant is NG/MRIMA Y/09/006.
Yield parameters such as number of fruits harvested were considered important
indicators for the Fusarium wilt Table (4), in this study, the tomato fruits were harvested when they
were firm and their colour fully developed. The number of fruit Iplant of the control is higher than
the infected except in some cases which could be as a result of environmental factors, thus the
Fusarium affects the number of fruitiplaI1t.NGIMRlMAY/09/006
produces the highest number of
fruit under infection, with strain 1 with having 4 and strain 2 with 2.67
The incidence was compared among the varieties during the study on Table (2), both
partially and incompletely wilted plant were encountered on the field, the result shows that the
incidence of fusarium wilt on tomato is high in NGIMRIMA Y/09J005, having 3.50 to strain 1 and
3.00 to strain 2 while NGIMRIMA Y/09/006 shows minimum resistance to the infection, having 2.33
