The comparison of agronomical and quality characters of Karacadağ rice landraces with some breeding cultivars in Southeast Anatolia region ecology

Diversity in genetic resources forms the basis of plant breeding studies. Landraces and primitive forms are important gene pools as genetic basis to solve future problems of cultivated plants or to transfer new characteristics to cultivated plants. In this study conducted to determine of yield and quality properties of Karacadag rice landraces grown widely in Karacadag ecological conditions of Southeast Anatolia Region and to compare with some commercial rice varieties in 2010 vegetation seasons total 14 rice genotypes consisting of 3 landraces and 11 breeding cultivars from foreign origin were used as material.Karacadag rice landraces were showed higher values than breeding cultivars in terms of the number of panicle (18.84-11.95), the number of grain per panicle (125.6-109.9 adet), panicle length (21.06-15.66 cm), grain weight per panicle (1.864-1.690 g), hectoliter weight (79.77-73.66 kg) and unbroken rice output rate (67.45-57.94 %). But, 1000 grain weight (30.93-33.69 g) and unit area grain yield (480.7-516.0 kg/da) values of landraces were at the back of breeding cultivars. Karacadag rice samples grown taller in excess of 100 cm and extremely tillered. Grain length of local populations was noticeably shorter than breeding cultivars. It was concluded that these Karacadag rice landraces can contribute in developing of high yielded cultivars.Beşer and Edirne from commercial cultivars have the longest values in all varieties in terms of the grain length and, the all breeding cultivars showed high values than landraces. It was determined that Şumnu and Kızıltan cultivars were the short length and resistance to lodging and, Osmancık-97 showed distinctive a superiority for the number of grain per panicle in Diyarbakır ecological conditions. That Beşer, Kızıltan, Halilbey and Gala rice cultivars have the superior values for grain yield, grain weight per panicle and 1000 grain weight, drawn conclusion to pervade of high yielded rice cultivation with using of these cultivars in Southeast Anatolia Region ecology
