- FIELD PERFORMANCE AND EVALUATION OF SOME SOYBEAN GENOTYPES SUSCEPTIBLE – RESISTANT TO COTTON LEAF WORM
Abstract: The field performance, genetic parameters and interrelationships among characters of 14 soybean genotypes susceptible-resistant to cotton leaf worm were studied at Giza research station in 2003 and 2004 summer seasons. The temperature in the first season was more favorable for soybean growth and hence increased the yield and yield components. The overall means of seed yield/plant were 71.8 and 67.1 g in the first and the second seasons, respectively, with ranges of 40.2 – 96.8 and 26.8 – 94.9 g/plant in corresponding season, respectively. The genotype Giza 111 gave significantly the highest seed yield. Strong negative correlation was observed between number of leaf-hairs and insect-resistance level (r = -0.678** and -0.630**), indicating that dense leaf-hairs is related to high resistance level. Since number of hairs had high estimates of heritability and G.C.V value, selection for this character would be useful as indirect selection for insect resistance.
