IDENTIFICATION OF NEW QTL CONFERRING RESISTANCE TO ANTHRACNOSE (ASCOCHYTA RABIEI) IN A RIL POPULATION OF CHICKPEA

Arzu YILDIRIM, Abdullah KAHRAMAN, Frederick John MUEHLBAUER, Bahattin TANYOLAC

Abstract

Ascochyta blight (AB) is a consistent problem affecting large growing areas of chickpea in all countries where this crop is cultivated. This disease is capable of causing large yield losses under conducive environmental conditions. To characterize the genetics of resistance to AB in chickpea, a population consisting of 77 recombinant inbred lines (RILs) derived from an inter-specific cross of Cicer arietinum (FLIP84-92C, resistant parent) x Cicer reticulatum Lad. (PI 599072, susceptible parent) was used. Each RIL and the parents were inoculated with blight spores by spraying. The RILs were scored for disease reactions under greenhouse conditions at 20 °C in a 12 h photoperiod. A linkage map was constructed using RAPD markers. Eleven linkage groups were obtained, of which three were small. The map spanned 889.1 cM with an average marker density of 10.1 cM. Two QTL were detected on linkage groups 1 and 4, which together explained 31% of the total phenotypic variation for AB resistance. These markers can improve precision of molecular breeding in this population.

Effects of Different Water Stress Levels on Biomass Yield and Agronomic Traits of Switchgrass (Panicum virgatum L.) Varieties under Semi-Arid Conditio

Erdal GONULAL, Suleyman SOYLU, Mehmet SAHIN

Abstract

A field experiment was conducted in the Wielkopolska region at the Gorzyń Research Station, Poland (52.34°N, 15.54°E) in Central Europe. The study was conducted over a 3-year period (2017, 2018, 2019) as a two-factorial design with four replications in the RCBD. The aim of the research was to determine the effect of the cultivar (‘Bolero’, ‘Tytan’) and the inoculation (Nitragina–seeds inoculation, Nitroflora I–seeds inoculation, Nitroflora II–soil inoculation, HiStick® Lupin–seeds inoculation) on plant development, seeds chemical composition and yielding of narrow-leaved lupin. The weather conditions and experimental factors significantly influenced on productivity of narrow-leaved lupin ‘Tytan’. Drought during the growing season reduced seeds and protein yields. After inoculation of HiStck the seeds yield was significantly greater by 12.4% (p < 0.01) and the protein yield after application of Nitroflora I or HiStick by 13.9% (p < 0.01) and 19.2% (p < 0.01), respectively. Correlation coefficients showed strong relations between number of pods and seeds per plant in both cultivars regardless of the inoculation variant, however the strongest relations in both cultivar were proved on HiStick treatment.
