| Abstract |
This work was conducted in the research farm of Mallawi Agricultural Research Station, Minia Province, Egypt during two successive seasons, 2003 and 2004, to study the role of genotype and its interaction with four inhabiting predaceous arthropods, i.e. ladybird beetles, Coccinella undecimpunctata L. (Coleoptera: Coccinellidae); lacewing, Chrysoperla carnea (Stephens) (Neuroptera : Chrysopidae); the rove beetle, Paderus alfierii (Koch) (Coleoptera : Staphylinidae) and unidentified true spiders (Araneidae), in improving the productivity of 19 soybean i.e. H3Z, H24Z, H26Z, H30Z, H37ZBC, H75ZBC, H48/S1, H52/S2, H60/BS, H65/S, F10H54, F9H2/12, H15L5, H16L2, H20L1, Giza 82, Giza 11, Clark and Crawford. Direct count sampling technique was used to estimate adult stages. The results obtained in this study indicated significant differences among those species of predaceous arthropods and all genotypes of soybean throughout the two combined investigation seasons.
The results indicated significant differences among soybean genotype in all traits studied where plant heights of the genotypes H26Z, H24Z, Giza 111, F10H54/BS, H48/S1, H20L1, F9H2/12 and H15L5 significantly surpassed the other genotypes. The shorter the earlier flowered and matured plants were belong the genotypes Giza 82, H48/S1, H60/BS, H73ZBC, H3Z, H30Z, H15L5, H20L1, H16L2 and Clark, where the earliest of them is Giza 82, which matured two weeks earlier than genotypes. The highest numbers of pods and seeds per plant were recorded to the genotype H73ZBC followed by H24Z, H60/BS, H30Z, Giza 111, H26Z. the new released variety Giza ili was recorded as the highest genotype for seed yield per feddan followed by the commercial variety Crawford. Giza 111 also gave the highest seed yield per feddan followed by the genotype H30Z, H26Z, F10H54/BS and H15L5. It is recommended that Giza 111, H30Z, H26Z, F10H54/BS, H60/BS, and H15L5 are to be considered as the best high yield and resistant genotypes to cotton leaf worm for the Middle Egypt Region. Improving productivity in El-Minia province will be increased through growing such high yield and resistant genotypes to cotton leaf worm resulting decreasing the costs of production and reducing the environmental pollution via avoiding pesticide use in soybean fields
