“…The field experiment was conducted from April to July 2-19 (dry season) at Mekar Tanjung village, Curugkembar district, Sukamandi-Indonesia, well-known as panicle blast endemic areas. One hundred and twenty-two advanced rice lines tested with six check varieties (leaf blast-resistant: INPARI 22, INPARI 39, and INPARI 41; leaf blast susceptible: Ciherang, Situ Bagendit, and INPARI 30), managed for Augmented field statistic design [18,19] with five blocks (Figure 1). The planting space was 25 cm × 25 cm, with a plot size of 5 m 2 per genotype.…”

Harvest failure due to blast (Pyricularia oryzae) in Indonesia was ranked fourth during 2015-2020. Establishing a panicle blast-resistant rice variety is crucial to prevent broader damage. The research aimed to evaluate the yield productivity at the blast endemic areas. The field experiment was held from April to July 2019 at Curugkembar Sukabumi. The statistic field design used Augmented with five blocks to manage 122 advanced rice lines in total, and six check varieties included leaf blast-resistant varieties. Pest and disease control based on Integrated Pest Management (IPM) standards, except for blast disease. Leaf blast infection occurs from vegetative and lasts to generative, which then continues to be a severed panicle blast. All tested lines and varieties were infected, with different severity. Two rice lines were resistant to panicle blast (scale 0), two lines were moderate resistant (scale 3), and the rest were susceptible (scale 5-9). The results of the augmented analysis for yield production showed that BP30533D-SKI-29-3-3 (8.96 t/ha) and BP31501D-SKI-28-1-0-0 (7.69 t/ha) lines were significantly better than INPARI 41 (3.6 t/ha) but susceptible to panicle blast (scaled 5 and 7). This result indicates that yield testing and blast screening would be better to run simultaneously.
