INHERITANCE OF IN-VITRO CALLUS PRODUCTION IN CHICKPEA

Kh.Alizadeh, M. Valizadeh, M.Khosrovshahly, F.R.Khoii, M. Ghadimzadeh

Abstract

Seven genotypes were randomly taken among accessions of Cabuli chickpea (Cicer arietinum L.) in Iran which were previously characterized as being able to initiate callus. The cultivars were crossed to generate a seven-parent diallel set, with reciprocals; and the progenies were evaluated for callus production. Significant differences (p<0.01) were found among crosses and for general combining ability (GCA) effects. However Specific combining ability (SCA) and reciprocal effect were found to be nonsignificant (p >0. 05). Estimate of heritability (h2) for callus production on plot mean basis was 60 %. Since, heritability was relatively high, and no reciprocal effects were detected, breeding strategies using any selection methods including recurrent selection should result in the development of high in-vitro callus producing populations.

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.
