    Agro-morphological variation of pigmented rice landraces from South Sulawesi grown in a temperate glasshouse of New Zealand
    (IOP Publishing, 2021-07-15) Hanifa AP; Millner J; McGill C; Sjahril R
    The present study is aimed to compare the agro-morphological traits of 15 pigmented rice landraces and two modern rice varieties grown in the same environment. The selected rice were cultivated in a greenhouse of Massey University, New Zealand using a randomised complete block design with five replications. Data collection included agro-morphological observation and measurement. Quantitative data were analysed with analysis of variance, followed with Tukey HSD. Result showed considerable variability in seedling vigour, lodging, plant height, panicle exsertion, panicle thresh ability, spikelet fertility, and maturity among the studied pigmented rice landraces. Panicle exsertion and spikelet fertility indicate plant cope toward environmental change, which was performed better by many landraces than modern varieties. Variability in morphological characteristics was also recorded among tested varieties. Utilisation of the trait diversity can be useful for future breeding programs, which can lead to this crops' improvement, including pest and disease resistance and grain quality research.

    Comparing satisfaction index on traditional pigmented rice plant attributes between upland and lowland farmers
    (IOP Publishing, 2021-07-15) Hanifa AP; Millner J; McGill C; Sjahril R
    This study is conducted to evaluate the satisfaction index of traditional pigmented rice plant attributes from farmer perspectives. Farmer respondents are selected from two regions of traditional pigmented rice producers in South Sulawesi: The lowland of Jeneponto and the upland of Toraja. Face to face data collection using questionnaires are used as a research instrument. Respondents were required to rate the importance and satisfaction of plant attributes based on five-point Likert scales. The answers are analysed using Customer Satisfaction Index formula. Result showed that the satisfaction index in the lowland of Jeneponto is higher than in upland of Toraja, as much as 67.16 and 56 respectively. Similar agreement from both lowland and upland farmers was found in lower yield performance of traditional pigmented rice than expected. As the end-user of released varieties, farmers' perspective on importance and satisfaction level on plant attributes is essential for guidance in breeding and varietal improvement.
