62 Mallsoor KazinzEach year diverse materials, possessing economic traits,disease resistance, wide adaptability and stress tolerance wereintroduced. These promising introductions in each group of cropsare indicated below:I. Promising IntroductionsWheat : Semi-dwarf, oligo culm spring type bread wheat (EC122043), dwarf oligoculm with branching habit (BC 122044 exIsrael), Sabergeg (EC 124298), Ajiba 69 (EC 124299), Mexi-Pak (EC-124300) all from Iril-q. Livorne-WIR 5841 (EC 130595) andRumanico-WIP 5862 with high protein content and cold resistanttypes from USSR, Fortune (EC 133489), hard red grained springwheat with stem solidness and male sterile line (EC 137254) fromUSA. Wialki CN 8242 a variety introduced from Australia derivedfrom a cross involving Madden x Boral is a hard, red grained type,superior in grain quality and possess resistance to Urocystisagropyri and Puccinia graminis race Sr 13. Sukota-N-82 (BC 158114ex Australia) is yet another variety derived from Tenson x IRN 67-451 (North Dakota), a mid season type with good quality andresistance to prevailing field races of Puccinia recondita andUrocystis agropyri.BC 183950-57 from UK having yellow rust resistance, EC258472 from Canada - a rust resistant line, cold tolerant, hardgrain/red grain typed BC 278274.:321 from USSR, BC 328914 and15 with PM II gene for resistance to powdery mildew from Japan,differentials for Helminthosporium leaf blight (BC 336670-73) fromBangladesh, EC 368167-69 male sterile and restorer lines fromFrance, were promising.Among hard wheat (Triticum durum), promising typesintroduced were Coast C-71 (BC 124293), Senator Copella (EC124294), Jwice-6 P (EC-124295) and Sin-AI-Jamel (EC 124296) allfrom Iraq, besides resistant sources to Erysiphe graminis (exCanada), isogenic lines resistant to powdery mildew and yellowrust from USA. Strains resistant to nematode (Heterodera avenae) areEgyptian Cl-12345 (BC 170660), Aus-Po 894 (Ex Denmark),powdery mildew resistant accessions chul/SCC-CCI 41120, CI1121, CI 12632, Transec CI (EC 159057-60) all from USA and springwheat (WWI46-73) from USSR with high number of grains/spike,and EC 198033-37 (T. compactum) also from USSR.
