بررسی و ارزیابی تحمل لاینهای پیشرفته گندم نان بهاره نسبت به عارضه جوانه زنی روی سنبله قبل از برداشت با ارقام و لاینهای رایج منطقه

In orther to evelaution of preharvest sprouting and obtaing tolerant varieties for upland region 7 genotypes including wheat varieties and advanced ',ines were evaluated based on randomized complete block dcsicgn in upland (ziartkola) and Low land (Biekola AgricuJture Resen !"clt Station in mist irrigation) condtions during 2007-2008. In this J'csearch mist irrigation was used at physiological maturitg condtion for two weeks. Signifant mean square for per harvest sprouting revaled significant diference of genotypes. Mean campa rison for mistirrigation condtion showed two lines including BOW/NKT and Nai 60 with ]9 ,tod 19.66 percent sprouting respectivclg were more tolerant then other genotypes. In uplaned condition due to Low rainil1g at physiological maturity time only yield of genotypes was studied. Tow genotypes including Ni60 and S\V89 with 262Kg/he and 25] 4 ~g/he respectively were superior than other genotypes. Key Words: preharvcst sprouting, wheM , yield, mist irrigation condition
