Abstract

This research was carried out at Barry Al- Garby village, Al Salameah region during 2017/2018 season to study the effect of spraying with yeast suspension and plant density on some growth and productivity traits of faba bean crop (var. Kubrusy). Three concentrations of yeast solution were used (2, 4 and 6) g/l in addition the control treatment. Three densities were studied (12.5, 16.7 and 25 plants/m2). A split plot design with three replications was used. Spraying with yeast suspension (6) g/l caused a significant increase in plant height (75.21) cm, number of branches/plant (3.65), pod length (11.33) cm, number of pods (11.18) pod/plant, weight of dry seeds (33.37) g/plant and seed yield (0.58) kg/m2. Increasing plant density to (25) plant/m2 caused an increase in plant height (75.2) cm, the first pod height (18.57) cm and seed yield (0.53) kg/m2, while it caused a significant decrease in number of branches/plant (2.97), number of pods(6.5) pod/plant , weight of dry seeds (21.12) g/plant. Spraying (6) g/l of yeast and planting (25) plants/m2 gave the highest seed yield (0.69) kg/m2.

Abstract

The study was carried out at AL-Sfireh location which belongs to Scientific Agriculture Research Center in Aleppo during 2016/2017, in  order to study the phenotypic-genotypic correlation and to define the most important selection indicators by path coefficient analysis of seed yield traits. (28) genotypes and two varieties i.e. Ghab4 and Ghab5 as control were planted in two experiments (under drought stress and non-drought stress conditions) in randomized complete block design with tow replications. The traits (100-seeds weight, number of pods per plant, number of seeds per plant, plant height, no. of days to flowering, no. of days to maturity) were studied. The results showed significant differences among genotypes for all traits in both experiments, the correlation analysis showed a positive and significant relationships between seed yield and number of pods per plant, number of seeds per plant, 100-seeds weight and plant height, while a significant and negative correlation was noticed between seed yield and no. of days to flowering and no. of days to maturity under drought stress experiment and in the non-drought stress experiment. Positive and high significant relationships were recorded between seed yield and number of pods per plant and positive significant correlation was recorded between seed yield and number of seeds per plant and 100-seeds weight. Path coefficient analysis exposed that number of pods per plant had the highest positive direct effect on seed yield followed by 100-seeds weight, but number of pods per plant had the highest positive indirect effect on seed yield through the number of seeds per plant followed by plant height whereas no. of days to flowering and no. of days to maturity had the highest negative indirect effects on seed yield through the number of pods per plant under drought stress experiments. Also, under non drought stress experiments number of pods per plant had the highest positive direct effect on seed yield followed by 100-seeds weight but number of pods per plant had the highest positive indirect effect on seed yield through number of seeds per plant followed by plant height. This study confirmed the importance of number of pods per plant, 100-seeds weight and early flowering as indicators for the development of drought tolerant genotypes.

Abstract

The study was conducted at Izraa Research Station, General Commission for Scientific Agricultural Research (GCSAR), in Syria during two growing seasons 2010 and 2011. Fifteen tetraploid wheat genotypes (2n= 4x=28) were planted under rainfed conditions (4 genotypes belong to species Ttiticum carthlicum, 3 genotypes belong to species Ttiticum polonicum, 8 genotypes belong to species Ttiticum dicoccum), and three local checks sham3, sham5, and Douma1, in randomized complete block design (RCBD), with three replications. Correlations and path coefficient analysis between yield components (number of fertile tillers, spike peduncle length, number and weight of grains per main spike, thousand grain weight) with the individual plant grain yield. Results showed that grain yield had a positive significant correlation (P≤0.01) with each of number of fertile tillers, spike peduncle length, number and weight of grains per main spike (r=0.636**، 0.366**،0.656**، 0.509**), respectively. Results of path coefficient analysis showed that the direct effect of number of fertile tillers on grain yield was high and positive (0.743), while the direct effect was medium and positive for each of number and weight of grains  in main spike and also  thousand grain weight on grain yield (0.239, 0.285, 0.21), respectively. Results also showed that number of fertile tillers had  the highest contribution %  in yield (55.32%), followed by the indirect effect of number of grains in main spike through the weight of grains in main spike (13.15%), then the direct effect of each of number and weight of grains in main spike (8.60, 8.17%), respectively. The study confirmed the importance of number of  fertile tillers, and number and weight of grains per spike, as selection indices for high yield in wheat, because of their significant correlation, and high relative importance with yield, either through direct or indirect effects.

Key Words: Wheat genotypes, Yield components, Correlation, path coefficient analysis.

Abstract

The study was conducted at Izraa Research Station, General Commission for Scientific Agricultural Research (GCSAR), Syria, during 2012/2013 season. Eight genotypes (3genotypes belongs to the species Triticum. carthlicum, 2 genotypes belongs to the species Triticum. polonicum , 3genotypes belongs to the species Triticum. dicoccum, and tow local checks sham3 and sham5, which were planted in Randomized Complete Block Design RCBD with three replications. Correlations and path coefficient analysis between yield components (number of total and fertile tillers, number and weight of grains per spike, thousand grain weight, individual plant yield) were studied. Results showed that grain yield had a positive significant correlation with both of number of total and fertile tillers (0.849**,0.932**) respectively, but number of total tillers had a positive significant correlation with number of fertile tillers (0.926**), while negative significant correlation was noticed with the number of grains per spike. The correlation was positive and significant between weight of grains per spike and with both of number of grains per spike and thousand grain weight. The results of path coefficient analysis showed that the indirect effect of number of total tillers on grain yield through the fertile tillers was positive and high (0.850), and was very close to the direct effect of the number of fertile tillers on grain yield (0.918), and the direct effect of grain weight per spike on grain yield was positive (0.322), and it’s indirect effect was negative and medium through the number of fertile tillers, and the indirect effect of thousand grain weight on grain yield was positive and medium through the weight of grain per spike (0.213). This study recommends to pay attention to the number of fertile tillers and grain weight per spike as a selection index of grain yield in the breeding programs, because of their high correlations an direct effect on yield.

Abstract

The study was conducted at Al-Ghab Research Centre, General Commission for Scientific Agricultural Research (GCSAR), Hama, Syria, during two growing seasons 2012/2013 and 2013/2014. Eight primitive wheat genotypes; C49, C57,and C64 belongs to Ttiticum carthlicum; P149,and P193 belongs to Ttiticum polonicum; D94, D124,  and D67 belongs to Ttiticum dicoccom, and two local cultivated varieties sham3, and sham5 (as control) were planted in randomized complete block design in three replications. Yield components (number of fertile tillers, number and weight of grains per spike and weight of thousand grain) were studied and compared to the  control and also the correlation coefficient  between the studied traits was determined. Results showed that the genotype D94 was significantly superior in number of fertile tillers comparing to both controls, and the genotype P194 was significantly superior in weight of grains per spike with an increase rate (76.65, 97.99)% as compared with both controls, sham3, and sham5, respectively, and also was significantly superior in weight of thousand grain with  an increase rate (72.73, 107.28)% as compared with both controls; sham3, and sham5 respectively. The results also showed a positive correlation between number of grains per spike and with each of weight of grains per spike and weight of thousand grain.
