The more frequent race was PTTS (23.07%) followed by race PTTT (12.30%), race TTTS (9.23%), race TTTT (6.15%), race PTTP (4.61%) and the two races PSTN and PTKS which were represented by (3.07%) each. The rest of races were represented by (1.53%) each. However, the more effective leaf rust resistance genes were i.e. Lr2a (73.84%), Lr2b (61.53%) and Lr36 (50.76%). On the other hand , the highest virulence were observed with Lr's i.e., 10; 11, 14b, 17; 16, 21, 30; and 2c, 3, 24 which were represented by 100% susceptibility; 98.46%; 96.92% and 95.38%, respectively. Leaf rust resistance gene(s) probably present in four Egyptian commercial wheat cultivars in comparison with nineteen leaf rust near-isogenic lines against 65 isolates, the cultivars Gemmiza 10, Giza 168 and Sakha 94 probably have Lr's i.e. 9, 16, 24, 11, 17, 30 and 14b. On the other hand, the tested Egyptian wheat cultivars were postulated to the lack of Lr2a, Lr2b and Lr36 which were proved to be the more effective genes in the present study. These results will remain an integral part of resistance breeding program and studies relevant to the epidemology and evaluation of virulence to leaf rust pathogen populations. }, keywords = {Annual survey,avirulence / virulence formulae,gene efficacy,leaf rust pathotypes(Pt),Physiological races,postulated genes,wheat leaf rust near – isogenic lines (NIL's)}, url = {https://jppp.journals.ekb.eg/article_86700.html}, eprint = {https://jppp.journals.ekb.eg/article_86700_32ad390f7defe9903705f75da58e6f46.pdf} } @article { author = {Mahmoud, M. and El-Sebai, O. and Shahen, A. and Marzouk, A.}, title = {EFFICACY OF JOJOBA OIL AGAINST TWO STORED LEGUME SEED INSECT PESTS Callosobruchus Maculatus (F.)

A negative correlations were observed between the jojoba oil concentration and all evaluated biological parameters, fecundity, egg viability, developmental period of the immature stages, adult emergence, broad bean seeds viability and seeds weight loss percentage for both tested insects C. maculatus and C. chinensis. The obtained results cleared that C. chinensis was more susceptible to jojoba oil than C. maculatus andthere is a significant difference between the two tested insects in all tested biological aspects regardless to the concentration (for the fecundity 168.33 and 190 eggs/female, hatchability percentage 60.33 and 69.5 %, developmental period 26.3 and 28.3 days, and 36.33 and 45.33 F1 emerged adults and weight loss percentage 6.02 and 7.56%, respectively. The highest concentration 7000 ppm gave a complete protection of seeds with zero weight loss percent for both tested insects. The mean percentage of weight loss in untreated seeds was 16.04, 12.96%, for C. maculatus and C. chinensis respectively, while, weight loss% reduced to more than the half averaged 7.56 and 6.02% for treated seeds. The residual effect of jojoba oil treatments was clearly effective in the first month of storage period which gave a 100% protection of treated bean seeds with 0.0 F1 emerged adults in both tested insects (100% mortality of developmental stages). After six months of storage period, residual effect of jojoba oil reduced by the storage period prolongation, While, jojoba oil still could protect the broad bean seeds against C. maculatus and C. chinensis attacks although the efficacy of jojoba oil decreased with aging 79.92 and 61.86% reduction of F1 adult emergence compared to untreated control.
