Found of Best Ragreation Equation to Estimation of the yield of soybean Genotypes ( Glycine max )

Abstract

Fourteen genotypes had bean choosed to found best regreation equation to estimated of yield of seeds of different maturated of soybean which cultivated in two plant densities , low with 300000 seed.ha-1 . and higher 600000 seed . ha-1 . in RCBD experiment with three replicates Values determination treatments for regreation equations in all varieties showed that number of seeds of plant was the important point to explaining of variation of single plant yield in low density , compaired with weight of seed characters in higher density , showed also that increasing of numbers of studied character in expected equation decreased of the error mean squares , while in creased values of determination coefficient which pointed to increasing of exacting these estimation equations .
