To date, there are no crop mutants described in the literature that display both Cd accumulation and tolerance. In the present study a unique pea (Pisum sativum) mutant SGECd(t) with increased Cd tolerance and accumulation was isolated and characterized.

This research was carried out in the multiple-environment trials (MET) which one is in Bayburt (40°24'05.7"N40°08'31.3"E)where the Black Sea geographical region located in the north of Turkey and in the Kahramanmaras (37°35'24.8"N36°48'49.4"E)where the Mediterranean geographical region located in the south of Turkey in 2016 and 2017 years.In this investigation, 6 registered pea cultivars (Bolero, Jof, Karina, Nihal, Reyna and Utrillo) and 2 wild pea genotypes (Pisum sativum L. subsp.elatius and P. sativum L. subsp.sativum) were used.The variance analysis showed a significant difference among Location (L), genotypes (G), genotypes×locations interaction (GL), genotypes×year interaction (GY), year×location interaction (YL) (all significant at P<0.01 level) and genotype×location×year interaction (GLY) (significant at P<0.05 level) interaction in terms of seed yield.Main effect genotypes (G) is explained 24.42% of total variation.This is followed by 18.78% (L), 17.87% (YL) 7.04% (GL), 4.91% (GY), 2.71% (GLY) and 1.12% (Y), respectively.Graphs were drawn according to the results of GGE biplot analysis and yield data of genotypes were evaluated according to these graphs.In accordance with GGE biplot analysis the seed yield first principal component explained 82.81% of the total variation and second principal component explained 17.19% of the total variation.

A research investigation was conducted to find out how Nickel's different stresses affected the morphological alterations in Pisum sativum. Pisum sativum has a complex stem structure. In the transactional view, the stem of Pisum sativum is usually more or less square-shaped. The root's transverse section has a form which is slightly rounded. The structural abnormalities of Pisum sativum treated with different concentrations of Nickel indicated its toxic effect on the anatomical structure of the root and stem. Pisum sativum treated with lower to higher doses of Nickel showed few specific effects on stem anatomy. Plants treated with nickel had many structural changes in their roots.

In different growth period,we spray different concentraction mangic acid solution on the surface of leaves of Pisum Sativum L.. The result show that the activity of SOD, CAT is promoted,the content of MDA and the speed of O~(·-)_2 production are reduced in seedling, buding and flowering period.We find that if spraying 0.1%～0.2% mangic acid solution on the surface of leaves in seedling, buding and flowering period,the production of Pisum Sativum L.was promoted.

In different growth periods,the different concentractions of manganese sulfate solutions are sprayed on the surface of leaves of Pisum Sativum.The results show that the activity of SOD,CAT is promoted,the content of MDA and the speed of O·-2 production are reduced in seeding,buding and flowering periods.Spraying 0.1%-0.2% of manganese sulfate solution on the surface of leaves of Pisum Sativum is best before flowering period.
