Abstract: Four field experiments were conducted at Sids Horticulture Research Station, Beni-Sueif Governorate, Horticulture Research Institute, Agriculture Research Center, during fall 2011, summer 2012, fall 2012 and summer 2013 seasons on snap bean (Phaseolus vulgaris L.). Sixteen genotypes (ten new lines and six cultivars) were evaluated for their yield and growth characteristics. Plant height, number of branches/plant, snap pod length , snap pod thickness, snap pod width, snap pod weight , number of snap pods/plant, number of dry seeds/pod, 100-dry seeds weight and early and total snap pods yield were studied. Also, the path analysis was studied. The results showed that Line 20 and 24 produced the highest snap pods yield/feddan in the four seasons. Results of path analysis showed that early yield, pod weight, number of pods per plant and number of branches per plant were the most important contributing traits to the total yield variability of bean. It is concluded that these results are important for designing selection criteria index in our snap bean breeding program.
