As for hybridization, the Violet forms were more compatible with the foreign varieties Roma and Makis than the Red forms. The local varieties were also compatible among themselves. The success rate of crossing was on average 50%.The genetic disjunctive generation analysis F2 shows that all characters with discontinuous variation (qualitative: color and shape of the fruit) follow a simple Mendelian genetic determinism. Moreover, heritability (in the broad sense) of some quantitative characters (size, number of flowers, number of fruits and weight of fruits) by the variance decomposition method can reach relatively high values (0.8 to 0.95) for some groups of crossings. The same holds good for heritability in the restricted sense (0.56 to 0.98) for some characters and groups.
A study on the nutritional and toxic substances of three wild food plants consumed in the Tshopo province of the Democratic Republic of Congo was made before cooking. It appears from this study that these berries may constitute dietary supplements of value as regards the crude protein, fat, calcium, magnesium, iron, phosphorus, and vitamins. However, many of these plants may also contain toxic substances (oxalates) or undesirable substances (tannins and saponins). All these results justify the use of these plants by the population in Tshopo province.
A study on the nutritional and toxic substances from leaves of four wild food plants consumed by the riparian population of Yoko forest reserve in Ubundu Territory in the Tshopo province of the Democratic Republic of Congo was made before cooking. It appears from this study that these berries may constitute dietary supplements of value as regards the crude protein, fat, calcium, magnesium, iron, phosphorus, and vitamins. However, many of these plants may also contain toxic substances (nitrites, nitrates and cyanides) or undesirable substances (alkaloids, tannins, sterols and terpenes). All these results justify the use of these plants by the riparian population of Yoko forest reserve in Ubundu Territory in the province of Tshopo.
