Abstract
The present investigation was carried out to study the symbiotic response of rhizobia under the influence of competition with native population and to section the most efficient and stable RhiStable rhizobium legume genetic system for simbiotik improvement of of vegan spaces for this purpose four different mutants including parent restrain of moth bean rhizobium strain Mr 125 H2 S2 cowpea rhizobium group and a local strength of cowpea rhizobium along with an uni no clotted control where taken since the cowpea rhizobium able to to infect six different host legume nine different variety of three different vegana is places where taken as host genotype the nine varieties and six extent of rhizobium including control where grown in all possible combination standard organic practice follow during the crop growth data were recorded on different yield component and symbiotic trips statical analysis was done in factorial rbd coloration and regression analysis were also done for few important trips analysis of variance revealed significant difference due to host genotype and rhizobium population for all the character study except for days to 50% flowering for which rhizobium difference were not significant interaction between the host genotype and rhizobium was also significant for all the treat study except for date to 50% flowering and number of seat per had the highest noodles was observed by eastern Mr 125 s to s m 8 hy5 aged 57 which was 30% more than the parent strength Mr 125 s2s M8 the relative contribution of host janu type rhizobium strain and host genotype X rhizobium interaction to total phenotype variation was computed following the fixed effect model of analysis of variance plant genotype comment contributed highest variety for all the character studied the host X strength interaction effect watch lower than stand affect the study of correlation coefficient between yield and other character indicate that the the highest polarization contributing character to what grain yield was nodal wait per plant followed by total and contain hundred seed hundred seed weight lhb contain board per plant and nodal number per plant the regression coefficient for explaining the host X interaction by difference between the slope of regression line so that copy variety RC 101 head hai mean grain yield with maximum slope of regression line indicating the high sensitivity response to word rhizobium in koh solution the barati aaye more 225 and soon enough from both been and have been spaces respectively are particularly interesting for stability for grain yield and total and contain the maintain their high yielding potential and the genetically diverse rhizobium population with a low slope of regression
