EVALUATION OF BLACK GLUTINOUS RICE GENOTYPES FOR STABILITY OF GAMMA ORYZANOL AND YIELD IN TROPICAL ENVIRONMENTS

Poramate BANTERNG, Anchalee JORALEE

Abstract

Gamma oryzanol is an important phytochemical of black glutinous rice as it has positive effects on human health. The objective of this study was to evaluate stability of gamma oryzanol content and grain yield for black glutinous rice genotypes grown under different environments. Twenty-five black glutinous rice genotypes and 2 white glutinous rice genotypes were evaluated during 2011 and 2012 in 8 farmers’ fields of Thailand. The experimental trials were laid out in a randomized complete blocks design (RCBD) with 3 replications. Soil data before growing, weather data during growing season, yield components, grain yield and gamma oryzanol content were recorded. The results indicated that location (L), genotype (G) and G×L interaction were highly significant for number of panicles per hill, number of filled grains per panicle, 1000-grain weight, grain yield, gamma oryzanol per grain weight and gamma oryzanol yield. The GGE biplot analysis indicated that KKU-GLBL-06-023 (V17), Khaokam Gs.no. 88084 (V5) and KKU-GL-BL-11-001 (V25) had both high mean performance and stability for grain yield. The superior genotypes for gamma oryzanol per grain weight were KKU-GL-BL11-001 (V25) and KKU-GL-BL-06-043 (V23). The desirable genotypes for gamma oryzanol yield were KKUGL-BL-11-001 (V25), Niewdam Gs.no. 21427 (V3) and KKU-GL-BL-06-043 (V23).

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.
