درسال 1367 به منظور تعیین تنوع جغرافیایی و ژنتیکی ارقام عدس موجود در کلکسیون بانک ژن حبوبات دانشکده کشاورزی دانشگاه تهران تعداد 760 رقم و لاین مربوط به 28 شهر ایران و 24 کشور مختلف جهان همراه با رقم زیبا به عنوان شاهد مورد مطالعه قرار گرفت. صفات مورد بررسی عبارت بودند از طول دوره کاشت تا 50% گلدهی و 90% رسیدن به روز ‘ ارتفاع گیاه به سانتیمتر ‘ شاخص برداشت بر حسب درصد ‘ وزن 100 دانه به گرم ‘ تعداد غلاف در هر گیاه‘ تعداد دانه درهر غلاف وعملکرد دانه برحسب گرم در 2 متر مربع. | ||

چکیده [English] | ||
This study was conducted to investigate the geographical and genetic diversity of lentil varieties (Lentil culinaris Medic.) available in the Pulse Crops Gene Bank, College of Agriculture, University of Tehran, Karaj, Iran. There were 760 lentil lines and varieties in the Gene Bank Collection and each was planted on a five meter row, with 0.5m spacing between rows. The lines had been collected from 28 Iranian localities and 24 foreign countries. One hundred seeds of each line were planted in every row on 10, 11 and 12 April, 1988. In this study variety Ziba (33—071-10450 Acc. No.) was planted after every 10 rows as check. The characters evaluated were as follows: 1 - Time from planting to 50% flowering in days. 2 - Time from planting to 90% maturity in days. 3 - Plant height in Cm. 4 - Harvest index (%). 5 - 100-seed weight in gram. 6 - Number of seeds per pod. 7 - Number of pods per plant. 8 - Seed yield per plot in gram. The one way analysis of variance with unequal samples was applied to the data obtained for each trait. Means and ranges for all characters were measured. The different genotypes of Iranian and foreign countries with different geograpical origin as well as the 34 genotypes selected randomly from them were classified in nine groups through cluster analysis. The analysis of variance showed that there were significant differences between the characters studied at the 1% level of probability. In this study the geographical area of Iran cities and other countries which are having similar climatical conditions were specified in one cluster. The genotypes from different geographical regions were grouped in the same cluster. It means that, the geographical variation and the genetic variation are not related with each other. | ||
