Abstract
In response to the growing trend of cultivating traditional rice varieties in the Galle District this study aimed to select suitable varieties that align with the preference of farmers and consumers. A survey of traditional rice varieties cultivated in the Galle district led to the collection of thirty traditional rice accessions from the Germplasm collection of the Plant Genetic Resource Center (PGRC) for preliminary evaluation with 4 traditional varieties from the Rice Research Station Labuduwa (RRSLd). Preliminary evaluations were conducted during the 2017
Yala season at the RRSLd. Subsequently, five accessions/varieties from the preliminary evaluations, six varieties from Regional Rice Research and Development Center-Bombuwala (RRRDCBw/RRSBw), and two improved rice varieties; (Ld 368 and Bw 372) were further evaluated during the 2017/18
Maha season using a Randomized Complete Block Design with two replicates in RRSLd. The evaluations involved the active participation of farmers, researchers, consumers, and traders. Varieties were assessed on eight morphological characteristics. using the pair-wise ranking method of the Participatory Rural Appraisal (PRA) approach. Data analysis was performed using the Kruskal Wallis One Way ANOVA model. Bw 372 and Ld 368 received above-average rankings, with
Suwandal (RRSLd) achieving the highest score for cooked rice quality. In the overall evaluation Ld 368,
Kahawanu (4250), Kuruluthuda (RRSBw), and
Suwandal (RRSLd) emerged as preferred choices. These selections were tested in farmer fields during the 2018
Yala season with Ld 368, Kuruluthuda (RRSBw), and
Kahawanu recording higher yields. In the 2018/19
Maha season, all the varieties tested in the 2018
Yala season were tested in farmer fields except Kahawanu (4250). Ld 368 and Bw 372 outperformed others in farmer fields. Based on farmer preference and yield performance,
Gonabaru (farmer selected) and Kuruluthuda (RRSBw) were the most preferred traditional rice varieties, followed by
Suwandal (RRSLd) and Rathdal (RRSLd).
