The Determination of Botanical Properties of Forage Kochia Population Grown in Konya Conditions

Abstract

Adverse soil and environmental factors cause a decrease in pasture yield in our country. Shrub species are given importance in breeding studies carried out in order to increase the yield in marginal pastures in the world. Forage kochia (Kochia prostrata), which is a naturally growing and semi-shrub in Turkey's flora, shows tolerance to adverse soil and climatic conditions. This research was established in Konya in October 2017 according to the Randomized Complete Block Design with 4 replications. In the research, the morphological and yield values of the forage kochia populations collected from 5 different locations in Konya (i.e., Karapınar Kartal Kayaları, Bahri Dağdaş I.A.R.I, Campus Beltway-Selçuklu, Ardıçlı Rural-Selçuklu, and S.U.F.A. Forage Kochia Demonstration Garden) were examined during 2018-2019. We investigated the blooming time (Scoring), plant height (cm), canopy diameter (cm), number of branch, stem diameter (mm), shape of habitus (Scoring), leaf length (mm), leaf width (mm), color of anther and stigma (Scoring), fodder yield per plant (g) and hay yield per plant (g). In this study, the Campus Beltway-Selçuklu Population (3P) bloomed the earliest in this area between the end of August and early September (Score 5,36). Among the forage kochia populations showing semi-decumbent habitus (Score 7,05-7,63) the Karapınar Kartal Kayaları Population (1P) had the highest yield potential regarding plant height (i.e., 46,63 cm), canopy diameter (i.e., 50,50 cm), fodder yield per plant (i.e., 112 g), and hay yield per plant (i.e., 45,28 g). In line with the findings obtained in the study, while the Karapınar Kartal Kayaları Population (1P) and the Campus Beltway-Selçuklu Population (3P) stand out in terms of yield and yield components. These results show us that each population is a valuable gene resource in plant breeding for pasture improvement.

WITHDRAWN: The Genetic Structure and Marker- Morphological Trait Associations in Forage Kochia Population Grown in Central Anatolia

“…In addition, since it does not burn during this period, it is a semi-shrub species that can be used for different purposes, such as re prevention strips (Koç Koyun and Acar 2022). In this study, which was carried out to examine the genetic relationships of superior genotypes selected from different forage kochia populations, the morphological characteristics of the selected plants were compared with the ndings of Koç Koyun and Acar (2021) working in the same region and other researchers working with forage kochia (McFarland et al 1990;Harrison et al 2000;Clements et al 2020; Lauriault and Waldron 2020) were determined. These differences may be due to the use of superior genotypes in our study and caused by the plants grown under abiotic stress due to the arid climate of our study area and the extreme structure of the soil, such as being saline and calcareous.…”

“…Molecular markers alone are insu cient in agricultural product development, and morphological markers are also needed to determine the plant's yield potential (Chahal and Gosal 2002). Therefore, in our study, 14 to 16 plants from each population, a total of 76 forage kochia, were determined, which were superior in terms of morphology and yield characteristics of ve forage kochia populations grown in Konya conditions (Koç Koyun and Acar 2021). Furthermore, in this study, PCR-based ISSR molecular markers determined the genetic relationships of these plants and the relationships between some morphological traits and ISSR markers for the rst time.…”

“…There are different ecotypes of forage kochia and variations in plant height, stem color and diameter, leaf size, maturation, growth period, and soil adaptation characteristics of these ecotypes (Kitchen and Monsen 2008). In addition, Koç Koyun and Acar (2021) stated that the forage kochia populations grown in Konya, Türkiye, have high variation in terms of morphological properties. Although there are different ecotypes in our country since forage kochia is the natural plant of our country, there is no steppe grass variety in Türkiye.…”

The Investigation of Some Morphological Characteristics of Forage Kochia Genotypes Determined Emergence Ratio

“…Kochia prostrata) is a semi-shrub C4 plant in the Amaranthaceae family and is used for the improvement of pastures with arid, semi-arid and salt-affected soils in the world (Harrison et al, 2000;Roth et al, 2017;Anonymous, 2019). Especially in the summer dry feed period, it provides animals with 3 rd and 4 th quality standard feed by remaining green Koç Koyun, 2021). In addition, with this feature, it can be used as a fire prevention strip to protect against wildfires that often occur in summer (Harrison et al, 2002;Koç Koyun and Acar, 2022).…”
