STABILITY AND ADAPTABILITY OF SORGHUM HYBRIDS ELUCIDATED WITH GENOTYPE–ENVIRONMENT INTERACTION BIPLOTS

Aamer MUMTAZ, Dilbar HUSSAIN, Muhammad SAEED, Muhammad ARSHAD, Muhammad Irfan YOUSAF

Abstract

This study was conducted to compare the performance of ten sorghum hybrids at two locations (Maize and Millets Research Institute, Yusafwala, Sahiwal, MMRI) & Sorghum Research Sub-Station, Dera Gazi Khan, D.G. Khan) for two consecutive years (2015 and 2016), i.e. in a total of four environments (MMRI-15, MMRI16, DG Khan-15 and DG Khan-16). The experiment was conducted in a Randomized Complete Block Design with a plot size of 4 × 0.75 × 2 m. In all four environments the crop was sown in July and harvested in December. Five plants were selected randomly from each plot for data collection. The following ranges were determined in the investigated traits; grain yield (2858.34-5266.33 kg ha-1 ), fodder yield (28663-45667 kg ha-1 ), days to 50% anthesis (76-81 days) and Brix value (8.28 -18.42). Analysis of variance (ANOVA) estimates, generated by the biplot software were used for data interpretation. It was found that the influence of genotype, environment and G × E interaction was significant (P<0.05) for all traits in all environments. The data for all traits except Brix value were useful for further study. For grain yield and fodder yield, hybrid YSH-95 was the most suitable due to its higher yield and better stability. Sorghum Research Sub-Station Dera Gazi Khan (DG Khan), a non-discriminating location, were considered suitable for generally adapted hybrids and Maize and Millets Research Institute, Yusafwala, Sahiwal (MMRI), a more discriminating location, were considered best for specifically adapted hybrids. The results of which-won-where biplots showed that Lasani was the best general hybrid at both locations, whereas YSH-95 was the best hybrid for the specific environmental conditions at MMRI.

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.
