Development of hybrids for Southern India

1. A perusal of the area covered under hybrids indicates that hybrids have not made a dent in the southern region.

2. It is because of the fact that people in southern India prefer medium slender grained premium quality rice like BPT 5204 but the existing hybrids are long grained and sticky.

3. Recently, Directorate of Rice Research, Hyderabad has developed a hybrid DRRH-3 and it is superior to BPT 5204 (the most popular variety with medium slender grain quality) both in terms of yield and grain quality traits.

4. This hybrid has been released in 2009 by CSCSN&RV for commercial cultivation in the states of Andhra Pradesh, Gujarat, Madhya Pradesh, Orissa and Uttar Pradesh. It is the first medium slender grain with BPT quality hybrid released in the country.

Development of Basmati Rice Hybrid

  1. Using the Basmati quality parental lines (CMS and restorer lines) developed at Indian Agricultural Research Institute, (IARI), New Delhi, the hybrid Pusa RH 10 was developed and it was released by CSCCSN&RV in July 2001 for commercial cultivation in the irrigated eco-systems of Haryana, Delhi and Uttaranchal. 2. It has an excellent grain quality early maturing hybrid, (in 115 days) as against 135 days taken by the best check variety Pusa Basmati 1, with 40% higher yield. 3. By virtue of its earliness, it is suitable for planting after the onset of monsoon without any yield reduction and has high per day productivity. 4.With the release of Pusa RH 10, the Indian Agricultural Research Institute and the Indian Council of Agricultural Research got credit of developing the world’s first superfine grain aromatic rice hybrids.

Grain quality

1. The cooking quality preferences vary from region to region. The quality in rice will have to be considered from the view point of milling qualit, grain size, shape, appearance and cooking characteristics.

2. A hybrid should possess high turnout of whole grain (head) rice and total milled rice, with varying length: breadth ratio (L/B) ranging from 2.5 to 3 mm and medium (5.5 – 6.6 mm) to long slender (> 6.6 mm) translucent grain, intermediate gelatinization temperature (GT) and amylose content (AC).

3. Besides this, high quality rices like Basmati should have length wise expansion without increase in girth coupled with distinct aroma.

4. The rice hybrids have grain quality features either better or on par with that of popular varietal checks like Jaya, IR 64 Annada and other popular local checks

5. Most of the hybrids have long slender grain type.

Packing and labelling the seed

1. Pack your seed in clean, preferably new, jute bags.

2. If you store your seeds in used bags, you should disinfect the bags to protect the seeds from insects that could attack the seed during storage.

3. Follow these steps to disinfect used bags. Turn the bags inside out and shake them thoroughly so no seeds of any kind stick to the inside of the bag. Soak the bags for 10 minutes in a 0.15% solution of malathion. (Make the solution by mixing 1 part malathion 50 EC in 300 parts water.)

4.Dry the bags under shade before filling them with seed.

5. Do not pack your seed if the moisture content is more than 13%. The seed would be spoiled during storage. Make two labels for each bag - one to place inside the bag and one to attach to the outside. 6. Each label should contain the following information: your name and address. the name of the hybrid. the location of the seed production field. season.

Seed germination testing

1. Before seeds can be packed and sold as hybrid seed, they must be tested for germination rate and purity. Public seed testing agencies normally do the testing and certification.

2. The germination rate must be at least 85% in order for seed to be certified. Before taking your seed for testing, you can do your own germination test at home by following the instructions.

3. Spread 200 seeds evenly over new or clean jute sacks that have been soaked in water. Cover the seeds with another wet jute sack.

4. Roll up the jute sacks with the seeds inside and store them in the shade for 7 days. Keep the rolled sacks moist for the entire period. Do not let them dry out.

5. Make three sets of 200 seeds. At the end of 7 days, count the normal seedlings that have developed. (Normal seedlings will have well-developed roots and shoots.)

6. All three sets of germinated seeds should have a minimum germination rate of 85%. A germination rate of 85% is 170 normal seedlings for each set of 200 seeds. If the germination rate of seeds is 85% or higher, the seeds can be packed.
