This work aims to do the study of the genetic variability of the local tomato.
The results showed that genetic diversity of local tomatoes is summed up into 6 botanical forms (round Red, round Violet, flat Red, flat Violet, elongated Red, and elongated Violet) among which round Red phenotype was the most represented (56.5%).
As regards the study of in vitro pollinic fertility, the best conditions for germination and elongation of the pollinic tube are obtained at 20 g/l sucrose, 0.62 g/l of boracic. On the whole, foreign varieties (Carotina, Marmande, Makis, Opal, Roma) have a weak indicator of viability as compared to local varieties. Fertility of different flowers analyzed according to their position on the plant, is generally decreasing from bottom to top. These results could explain some cases of failure of fertilization when crossing-over different varieties of tomatoes. The results also show the importance of choice of the flower used when sampling pollen grains.
