Overview

Strong tillering, sturdy plants and large panicles are complemented by resistance to two major rice threats and consistently appealing cooked-rice quality.

Hybrid rice combines two carefully chosen parent lines, giving plants extra vigour, stronger tillering and higher yield potential than conventional varieties. Farmers should buy fresh hybrid seed for every crop, as saved grain does not breed true.

KCR06-1 was nationally recognised in 2019 under the KC.06/11-15 national science and technology programme. It is grown across the Mekong Delta and does especially well in the rice-shrimp areas of Ca Mau, Kien Giang and Bac Lieu, where farmers value its salt tolerance, its low seed requirement and fragrant rice that traders buy at high-quality prices.

Key features

  • Fragrant F1 hybrid with long, non-chalky grain of about 7.3 mm
  • Resistant to brown planthopper and rice blast
  • Vigorous tillering means less seed per hectare; suits cluster sowing
  • Tolerates salinity of 4–5‰ in rice-shrimp areas
  • 8–10 t/ha, with potential of 12–14 t/ha

Growing guide

  1. Seed and landSoak and incubate the seed until it just sprouts. Level the field and drain it well so seedlings establish evenly, whether you broadcast, drum-seed or transplant.
  2. Seed rateSow thinly: a moderate seed rate gives sturdier tillers, better airflow and less disease. Drum or cluster seeding saves seed and makes the crop easier to manage.
  3. NutritionSplit nitrogen into several doses through tillering and panicle initiation and balance it with phosphorus and potassium. Avoid heavy late nitrogen, which invites lodging and pests.
  4. WaterKeep a shallow water layer after establishment and use alternate wetting and drying where you can: it saves water and cuts methane emissions. Drain the field 7–10 days before harvest.
  5. Crop protectionScout weekly for brown planthopper, leaf folder, blast and bacterial leaf blight, and spray only when local thresholds are reached, following plant-protection advice.
  6. HarvestHarvest when 85–90% of the grains on the panicle have turned straw-yellow, then dry the paddy promptly to about 14% moisture for storage.
