INHERITANCE OF FEMALE STERILITY IN INDUCED Cicer SPECIES

Abstract

Mutations play an important role to induce new genes, creating variation. The present study deals with inheritance of female sterilities in the induced mutants of the cultivated chickpea (Cicer arietinum L.) and its progenitor (Cicer reticulatum Ladiz.).  Air-dried seeds of Cicer species were irradiated with 200, 300 and 400 Gy gamma rays. Two induced mutations conferring open flower and determinate growth habit with small leaf characteristics in the cultivated chickpea and its progenitor were discovered in M2 generation. These mutant chickpeas were female sterile. Inheritance study showed that the female sterility in the induced mutants was controlled by a single recessive gene (fs). The female sterility, determinate growth habit, open flower and small leaf characteristics were first reported for C. reticulatum Ladiz. Results indicated that a joint segregation of the female sterility, open flower, determinate growth habit and small leaf characteristics might be linked in both of induced mutants of the cultivated chickpea and its progenitor. The new gene discovered on the sterility in the induced mutants may be useful for gene mapping in Cicer species.

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

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.
