GENETIC AND ENVIRONMENTAL VARIABILITY, HERITABILITY AND GENETIC ADVANCE IN POD YIELD, YIELD COMPONENTS, OIL AND PROTEIN CONTENT OF PEANUT VARIETIES

Fatih KILLI, Tahsin BEYCIOGLU

Abstract

In this study, genetic and environmental variability, broad-sense heritability, genetic advance and correlation coefficients of pod yield, yield components, oil and protein content of ten registered peanut varieties were examined. Year (Y), location (L), year x location interaction (Y x L), genotype (G), genotype x year interaction (G x Y), genotype x location interaction (G x L) and genotype x year x location interaction (G x Y x L) were significant, but G x Y for shelling percentage was not significant. Genotypic and phenotypic variances were highest for pod yield followed by hundred pod weight, whereas all investigated traits of peanut varieties were significantly different. Broad sense heritability estimates ranged from moderate level to high. Heritability values were estimated to be maximum for shelling percentage (95.4%), hundred kernel weight (91.6%), hundred pod weight (88.3%), while moderate for pod number (63.8%), pod weight (60.4%), first quality pod ratio (63.3%), pod yield (63.2%), oil content (52.0%) and protein content (52.5%). High heritability for shelling percentage, hundred kernel weight and hundred pod weight indicated that these characteristics were affected less than the others by the environmental conditions. The magnitudes of genetic advance were observed to be very high (>50%) for hundred pod weight, 100 kernel weight, pod weight and pod yield; moderate (20-50%) for pod number, first quality pod ratio, shelling percentage and low (<20%) for oil and protein content. Significant and positive relationships were found the pod yield and pod number, pod weight, hundred pod weight and hundred kernel weight.><20%) for oil and protein content. Significant and positive relationships were found the pod yield and pod number, pod weight, hundred pod weight and hundred kernel weight.

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.
