Indeed, the speculative nature of the meat market Bahhady et al. Results indicated the presence of sufficient variability to warrant selection. Triticum durum ; F3 selection; path analysis; intergeneration correlation; parent-offspring regression; response; realized heritability.

The species Vicia narbonenis L. Our results are similar to those obtained by Abd-El-MoneimMihailovic et al. Growth of SDI and world publication market. The research conducted in Turkey also shows that this species is very promising in rotation with wheat crop Durutan et segif. However, there occurs variations intra- and inter-annual that are very important. Bousselam and Massara genotypes exhibited a general adaptation, with a grain yield mean above the overall average. Article Information Editor s: The results obtained show large diversity among phenological ecotypes of Vicia narbonensis L.

The results showed that there was no effect of the system on the soil moisture. Analysis of variance of the characters measured on the 15 ecotypes of Vicia narbonensis L.

A set of cultural practices have been made for the establishment of the experiment. Direct and correlated responses to F3-selection for biomass yield, spike number, harvest index, kernel weight, plant height, days to heading and grain yield confirmed predictions drawn from intergeneration correlation and parent-offspring regression coefficients.

Parameters measured and statistical processing: Cultivation techniques, technical conventional-till, minimum tillage, wheat, soil, weeds. Ecotype produced average values of 2. Differences among genotypes explained 2. Path analysis emphasized the direct and indirect effects of biomass yield, spike number and harvest index on grain yield, suggesting that F3-selection based on one or simultaneously on all these traits would result in significant direct and correlated responses.

May 16, Revised: Each elementary plot consisted of 4 rows of 4 m long, 30 cm apart. In contrast, the ecotype is the latest with 79, 92, and days for the same phenological stages, respectively Table 3. Our results confirm those obtained in other studies indicating that the species Vicia narbonenis L.

Tolerance au gel apres acclimatation au froid chez le pois: Early sowing Bouzerzour H and Refoufi B. Given this situation, the development of grasslands for forage crops is an important developmental field to support sustainable mixed grain and livestock systems.

Genotype x environment interactions and some considerations of their 4. Concerning forage and grain production, the statistical analysis showed highly significant differences between ecotypes. Performance of Awassi lambs grazing common vetch in on-farm and on-station trials.

In terms of quality seeds, the results indicate a wide variability within ecotypes; the high total nitrogen content in narbon vetch grains could be a source of supplementary animal feed in the semi-arid and arid areas.

The overall results suggested that early generation selection should be restricted to plant height and days to heading while selection to improve grain yield directly or via related traits should be delayed to later advanced generation. The relationship between pairs of measured variables are described and analyzed by the calculation of phenotypic correlations based on the genotype averages. Average values of grain chemical composition of the Vicia narbonensis L. Half of the elementary plot was used to assess the potential forage production and a set of agronomic traits ; the other half was used to measure grain yield and to assess the quality of seeds produced.

This relationship shows that the altitude area or the low temperatures are frequent, that late ecotypes in flowering reduce their fertility and therefore reduce grain yield.

Those of late seeding were These resources consist mainly of by-products bran, straw and stubblegrazing on plants spontaneous fallow and rarely growing vetch, oats and barley CIHEAM, Despite the diversity of legume species available in Algeria, very few have been used specifically as a food source for livestock. Based on the 1, 2. Planting date management aimed factors such as moisture stress, high temperature, generally to avoid or to minimize stress effects on weed infestation, soil fertility, disease pressure and crop performance Tapley et al.

Correlations between grain yield s and phenological characters and Dry matter of the Vicia narbonensis l. Agronomic potential of three vetches Vicia spp. These results suggesting more reactive conditions under early suggested the potential of optimum planting date sowing.

In addition, these ecotypes are early enough to escape the summer drought stress. This area is under the dominance of a continental climate with high temperature ranges, both annual and daily.

The same results were found by Swtif and Abdelguerfion cultures of Vicia erviliaVicia sativa L. Late planted crop, is based on a better understanding of GEI pattern.

These results suggested the significant effect of both Table 2. Variability in phenological development and production: Based on work done by ICARDA, the production of dry matter and protein obtained in the biennial rotation cereal-legume forage is important. The ecotype is very early for the beginning of flowering, for full flowering, for the beginning of pods formation and for complete maturity.
