“…Other studies were based on the selection of perennial alfalfa (Medicago sativa L.) cultivars with high seed yield potential, focusing on its components (Askarian et al, 1995;Abadouz et al, 2010;Iannucci et al, 2002;Liatukiene et al, 2009;Sengul & Sengul, 2006;Bakheit et al, 2017). This criterion (seed yield) has little agronomic importance but is used to develop alfalfa cultivars with very good market value (Bolaños-Aguilar et al, 2000).…”

In Algerian Saharian oases, the surfaces reserved for local populations of perennial alfalfa (Medicago sativa L.) have declined significantly in favor of other introduced cultivars. Their preservation has become more than necessary. In this perspective, a study conducted over two successive campaigns, in an hyper-arid area of Algeria (Adrar region), focused on the expression of twenty seven (27) morphological and phenological characteristics related to plants, pods and seeds within seven (07) local populations of different provenances: El-Menea (Ghardaïa), Tamentit (Adrar), Timimoun (Timimoun), El Guerrara (Ghardaïa), Aoulef (Adrar), In Ghar (In Salah) and Temacine (Touggourt). The ecological factors (rainfall, temperature, altitude) of the alfalfa provenance environments were also considered. The trial was carried out in a randomized complete block design with four (04) replications. The results indicate the existence of a great morphological variability between the populations for traits related to flowering and pods. The study revealed very strong correlations, particularly between the number of pods per plant (NPPl), the number of seeds per plant (NSPl) and the number of flowers per plant (NFPl) during the two successive years. The rainfall and the temperature (provenance environmental factors) acted on almost the totality of the studied characteristics, whereas the effect of the altitude seems to be of less importance. The three factors (respectively, temperature, rainfall and altitude) would have an influence on the precocity of the populations Aoulef, Inghar, Tamentit and El menea which showed a better performance for seed number, in spite of the very difficult climatic conditions characterizing this region of the country.

This investigation was carried out at Agronomy Department Farm, Faculty of Agriculture, Assiut University, Egypt, to study the effect of temperature resulting from different sowing dates, genotypes and their interaction on forage yield and its components of alfalfa. A set of ten genotypes (Ismailia-1, Nubaria-1, Ramah-1, populations from F.R.S., Kharja, El-Dahlia, Farafra, Balady and Aswan and Cuf 101) were sown on five sowing dates (three at autumn, October 10 th (D1), November 10 th (D2), December 10 th (D3), beside two at spring i.e. March 20 th (D4), April 20 th (D5). Two experiments were carried out as experiment I (2017-2019) and experiment II (2018II ( -2020. Each experiment included all autumn and spring sowing dates. The split block design with three replications was used in both experiments. Fifteen cuts were taken in the two years from each sowing date for each experiment. The results showed that the sowing dates and genotypes had highly significant effect on plant height, leaves/stem ratio, total fresh, dry and protein forage yields for the two experiments, except total protein forage yield in experiment I among studied genotypes which was non-significant. While, the interaction between sowing dates x genotypes insignificant for all studied traits in the two experiments. The highest mean values of plant height obtained from the plants sown in fourth (March D4) and fifth sowing dates (April D5) sowing date were in the two experiments. While, sowing at November (D2) and December (D3) gave the highest mean values of leaves/stems ratio.Furthermore, the maximum total fresh, dry, protein forage yields were obtained from sowing at March 20 th (D4) in experiment I and from sowing on October 10 th (D1) in experiment II. It is remarkable results that the Ramah-1 genotype produced the highest total fresh, dry, and protein forage yields in the two experiments.Finally, the correlations between forage yield and its components revealed that total protein forage yield was positive and significant correlated with fresh and dry forage yield, but negatively correlated with leaves/stems ratio in two experiments.
