mean performance, correlation and path coefficient under irrigation with saline water in some genotypes of peanut (arachis hypogaea l.)

Abstract: Two field experiments were carried out at El- Arish Agricultural Research Station, North Sinai Governorate, in 2003 and 2004 seasons, to study the effect of irrigation with saline water on yield, yield components and seed oil of some peanut genotypes through mean performance, correlation coeffient and path analysis.
Results indicated that significant differences among twelve peanut genotypes under study for number of pods/plant, pods weight/plant, seeds weight/plant, 100-pod weight, 100-seed weight, shelling percentage, seed yield/fed as well as seed oil percentage in the two seasons and their combined analysis were observed.
Int 341 genotype surpassed the other peanut genotypes in most of the measured yield and yield components as well as some quality characters. Giza 3 recorded the highest value of 100-pod weight. Int .276 recorded the highest value of shelling percentage. While, Giza 5 gave the highest value of seed oil percentage. On the other hand local 404 recorded the highest value of measured characteristics, while. Int 342 genotype recorded the lowest oil seed percentage in the two seasons and their combined analysis. It was shown that Int 341 gave the highest values in most characters studied under irrigation with saline water and was the most salt tolerance one than the other studied genotypes.
Oil yield/fed appeared positive and significant correlation with number of pods/plant, weight of pods/plant, weight of seeds/plant, 100-pod weight, 100-seed weight, shelling %, pod yield/fed and seed yield/fed,
Other studied characters associated significantly and positively with each others. Oil percentage correlated negatively and insignificantly with the other studied characters.
Path analysis revealed that, the main sources of seed yield variation according to their relative importance were pod yield/fed (192.562) and seed yield/fed (103.877).
These results are of great interest for peanut breeder to select the most tolerant genotype to salinity and could involved in breeding program for salinity or could be recommended to be cultivated in marginal saline soil in Egypt.
