摘要
Landrace yellow-rice (Oryza sativa L.) has a wide variation in terms of agronomical characters. This research was carried out to determine the agronomic characters of landrace yellow-rice by selection works for three years. In the research, mass selection method was used. At the beginning, from the farmers' fields, plant selection was made according to phenotypical characters (plant height, panicle length and spikelet form) at physiological maturity. The selected plants were threshed and planted in the first year. The plants selected in the first year was harvested and threshed collectively and investigated in terms of panicle and grain properties. Plant selections and investigations were repeated in the second and third years. On the selected plants; tiller number, stem length, panicle height, grain number per panicle, grain weight per panicle, 1000 grain weight, test weight and length of grain were examined for three years and average values belong to examined properties were 4.47, 94.61 cm, 19.50 cm, 126.85, 2.97 g, 26.38 g, 55.15 kg and 6.23 mm, respectively. Additionally, variance, standard deviation and coefficient of variation were calculated for examined properties. According to the results of three years, landrace yellow-rice were determined as homogenous for investigated traits.
