The objective of this study was to analyze the genetic diversity present in twelve Algerian pea genotypes using 24 agro-morphological traits. The experiment was carried out during three growing seasons (2013 to 2014, 2014 to 2015 and 2015 to 2016). ANOVA analysis revealed the presence of a great genetic variability for all characters studied. This diversity might be used in breeding programs. Also, expression of characteristics is highly influenced by the environment. For quantitative traits, correlation studies showed that weight of 100 seeds was significantly and positively correlated with leaflet length. Number of pods per 1 m² has a positive significant correlation with leaflet width. Weight of pods per 1 m² was correlated with three characters: Stipule length, leaflet length and leaflet width. The principal component analysis revealed that three components explained 85.92% of variation. Two groups were noted by dendrogram. The first group (demchi 1, p069, bouch1, p539, p593, p595 and p596) was characterized by a high pod yield; the other group comprises the less productive genotypes (p071, sefrou, p072, p073 and p350). Otherwise, the genotype p593 produced the best results for pods yield.

Health is one of the greatest blessings a person can have, and it is priceless. Traditional medicine has always been and remains an important practice for human health. In all regions of the world, popular knowledge has acquired its own experiences in traditional medicine which are passed on from generation to generation and which have generated wonders in terms of innovation of effective traditional remedies which bear the fruit of the healing. After the release of the novel Covid-19 virus, several research studies have focused on the study of medicinal plants that fall under traditional Chinese or Indian medicine or others around the world, to try to put in place remedies against this virus. Chronic Diseases kill millions of people around the world every year. These diseases cause a weakening of the immune system in people who have them. As a result, health experts have classified those affected by these diseases as being among the most at risk in the event of contracting Covid-19. It is therefore obvious that preventing and combating chronic diseases helps to better cope with this Virus or others that may arise in the future. In this humble work, we have tried to make a small contribution that could help fight Covid-19. In the light of actual practices supported by bibliographic research, we try to recall some orientations of natural treatments against certain widespread chronic diseases namely: type 2 diabetes; arthritis and weak immune system (particular case of a low white blood cell count). The results of these treatments are very promising for healing and recovery; which opens doors of hope for those who are affected. Moreover, this subject deserves serious investigations through Research for a better consolidation of these therapies.
