Investigation of Forage Sorghum (Sorghum bicolor L.) Genotypes for Yield and Yield Components

The objective of this study was to evaluate the genetic variability of forage sorghum genotypes and to estimate genotypic, phenotypic, and environmental correlations with path and stability analysis. The experiments were conducted in Antalya and Konya locations of Turkey during 2014-2015 years by using 48 selected forage sorghum lines and 4 sorghum varieties. Experimental design was the randomized complete block, with three replications. Significant variations were recorded for all the characters among the genotypes. The highest plant height has been optained from 355.2 cm and 300.1 cm in Antalya and Konya location respectively. Days to 50% flowering ranged from 64.8-101.3 days in Antalya and 69.0-111.2 days in Konya. The highest forage yield was observed in Line-22 with 99.1 tha-1 in Antalya and in Line-41 with 75.5 tha-1 in Konya. Forage yield was significantly and highly positively correlated with hay yield (r = 0.9851**), plant leaf ratio (r=0.3478*) and stalk yield (r=0.9901**). Path analysis revealed the plant stalk ratio direct positive effect on forage yield. On the other hand, plant stalk yield had negative direct effect through forage yield. According to results of the stability analysis, Line-1, 3, 5, 13, 21,40, 42 and 44 were the most stable varieties

Determination of the Botanical Composition of Some Rangeland in Antalya Province

Bu araştırma, Antalya ilinin 6 farklı ilçesindeki doğal meralarda botanik kompozisyonu saptamak amacıyla yürütülmüştür. Ölçümler modifiye edilmiş tekerlekli nokta metoduyla yapılmıştır. Vejetasyon döneminde toplam 21 durakta 176 farklı tür tespit edilmiştir. Tespit edilen türlerin 34 adedi buğdaygil, 39 adedi baklagil ve 103 adedi diğer familyalara ait türlerden oluşmaktadır. Bitki örtüsünü oluşturan türlerin % 19.3"ü buğdaygil, % 22.1"i baklagil, % 58.5"i ise diğer familya türlerinden oluşmaktadır. İncelenen meralarda bitki ile kaplılık oranının % 71.9 ile % 95.1 arasında değiştiği saptanmıştır. İncelenen mera alanlarının mera durum sınıfının zayıf ve orta ayrıca mera sağlığı sınıfının ise sağlıklı olduğu tespit edilmiştir.This research was conducted to determine botanical compositions of the native rangelands in the six different district of Antalya Province. Vegetation of the rangeland was determined by the Modified Wheel Point Method. 176 plant species were determined at 21 locations in the vegetation period. Determined species consist of 34 grasses, 39 legumes and 103 other families. Determined species except bare ground and rocky areas, consist of 19.3% grasses, 22.1 % legumes and 58.5 % other family plants. It was observed that the rate of plant-covered area varies between 71.9 % and 95.1 % in the rangelands. It was determined that the rangeland condition class was "Poor" and "Fair" and also health class was healthy
