SELECTION WITHIN AND BETWEEN FARMER SEED LOTS OF EGYPTIAN CLOVER TO DEVELOP HIGHLY PRODUCTIVE POPULATIONS TOLERANT TO HIGH LEVEL OF SALINITY.

Seeds of selected nine populations and registered varieties were divided to evaluate at El-Serw Agric. Research Station of 2013-2014 and 2014-2015 growing season.
Combined and highly significant were observed for all studied traits, except green forage and dry yield/plot in the second cut, plant height, number of tillers per plant and number of seeds per head.
The performance of the studied genotypes was determined separately for each season. The genotype 5 ("108" from Farskour district) was the highest for total green fodder yield, total dry fodder yield, seed no/head, 1000-seed weight, seed yield per plot and seed yield per fed. While, the genotype 3 (103 from El-Zarka) recorded the highest for plant height.
The results revealed that the genotypic variance (VG) relative to environmental variance (VE) was large in magnitude for all traits except for total green fodder yield per plot.  The differences between genotypic coefficient variability (GCV) and phenotypic coefficient variability (PCV) were narrow, suggesting little effects of environments on these traits. Heritability in broad sense expressed low values for total dry fodder yield/plot, medium values for 1000 seed weight and seed number/plant and high values for other traits.  There were a positive significant correlation between seed yield/plot and each of 100-seed weight, no. of seeds/head and number of tillers/plant. The relationship between total green forage and total dry forage achieved a significant positive correlation between them.
It could be concluded that, selection in advanced generations of this populations is good to improve green and seed yields and also the genotype no. (5) was a new promising to produce as a variety tolerant for high level of salinity.
