The application of Seed vigour test, multiple regression model and path analysis for estimating final standing of Red bean(phaseolus vulgaris L.) cultivars plantlet

In order to study the relationship between Seed vigour tests, field emergence (FE) standing plantlet and to determine the cause and the effect relationship between them and finding multiple regression model for estimating field emergence, this study conducted on 16 Red bean cultivars contain: LQk-29, KIP31,AND-1007, D-18083, DOR-364, AND-925, MOC-59, MCD 2004, DOR-476, DCD 2004 RAB-58, RAB-484, RAB-505, XAN-194, RAP-50, GOLI NAZ in the base of randomized complete block design for field emergence and completely randomized design for laboratory experiment in 4 replication. some vigour tests as Ccold Test(CT), Accelerated Aging test(AA), T4, T7, EE, WE, WS, WE/ WS, LE/ LS, 100WS, ECS, ECW were done. The results showed that, in the case of mother seeds planted in field standing, 2 independent variables AA and WE/WS had significant effect at 1% level and their estimated coefficient were 0.00458011, 10.2569 and (b) amount calculated 0.2311. This model predicated %42 of field emergence. Direct and indirect effect relations were studied by Path analysis. The results indicated that, among characters and independent variables in 16 cultivars, AA with 0.558 had maximum correlation with FE. Its direct effect was 0.472 and showdsignificant effect at %1 level. It seemed that, this high correlation due to direct effect and other indirect effects did not showed significant effect and important rule. Correlation between EE and FE with 0.487 had significant difference at %1 level, but opposite to AA character, direct effect of EE was not the reason of this high correlation and indirect effects by AA with 0.271 were more important.
