Evaluating the morphological indicies effective on yield and yield component in different cotton genotypes
m Dadashi | b Kazerani
The interrelationships between the seed cotton yield with to traits of 8 cotton cultivars were studied at plant Institiute, Gorgan, Iran in 2004. The experimental design was randomized complete block design with four replications. The correlations between remaining characteres in yield were calculated. Stepwise regression and path analysis showed that, yield in first harvest, number of monopodial branchs, yield in second harvest could explain the maximum of variations of yield (R2=0/963). The yield in first harvest had the highest direct effects on yield/plant (P=1/087). Due to their high direct and or indirect effects on yield, yield in first harvest and yield in second harvest can be used as selection criteria to identify the high yielding genotypes.
