Possibility of green revolution: 850 rice lines developed
BdChronicle Special Report:
Bangladeshi plant Breeder and Geneticist Dr. Md. Nazmul Haque has developed new high yielding hybrid rice lines from a local rice variety by hybridization with indica rice.
With his relentless effort, Dr Shahin been able to developed a total 850 advance rice lines/ varieties after about 19 years of his devotion to rice science.
Using ‘Transgressive Sagreegant Breeding’ method these lines were developed from a low indigenous variety named ‘Dola Aman Dhan’
The varieties, life span are of about 105 to 145 days, also suitable in adverse climate which yields 33-40 maund per bigha (33 decimal), claimed the researcher.
The new varieties contain longer stem and higher biomass that provides the plant additional strength during storm.
Dr Shahin told that the rice could be cultivated both at high and low lands contain more iron and zinc than the traditional varieties. Even the amount of zinc at the some of these rice varieties is 46.38 ppm which is more than double of BRRI Dhan 64 (Zn content 22 ppm).
Farmers should be able to cultivate these varieties in areas having low temperature, saline soil, and water logged conditions throughout the year in Aush, Amon and Boro season.
There are some varieties among 850 varieties those could be cultivated even in Haor (water reservoir) Area and also be exported to other countries.
The new rice varieties could be cultivated with the one third costs for fertilizer and are capable to withstand against disease and insect than other varieties, added Dr Shahin.
Quality of the newly developed rice variety after cooking is very tasty like local rice and amylase content are like as other high yielding indica rice varieties, told Dr Fatema Hoque Shikha, professor of Fisheries Technology department of BAU.
Dr Shahin informed that- during Boro season 2013-14, he harvested about 7.5 ton to 13 ton/ha in the newly developed rice varieties.
Chan Mia, a farmer of Hatibanda village under Gabtoli Upzila in Bogra district told that he harvested about 32 to 44 mound per Bigha by cultivating the newly developed rice varieties in his field.
Dr Shahin and Chan Mia have harvested even 54 mound rice per Bigha from one part of their on farm trial, which is a record.
Chandidas Kundu, Deputy Director, Department of Agricultural Extension (DAE), Bogra, told that the results of Dr Shahins’s research finding are very much impressive but it should be done at larger scale and rechecked before extension of the newly developed rice varieties.
After visiting Dr Shahin’s research field at Hatibanda village under Gabtoli Upzila, Bogra, Nazmul Hoque Mondol, Upazila Agricultural Extension officer of DAE found some promising rice lines which will be
suitable for variety release among these 850 advance rice lines or variety.
Appreciating the research output developed by Dr Shahin, Professor of Genetics and Plant Breeding department of BAU also the Director of Bangladesh Agricultural University Research System (BAURES) Dr Luthful Hassan suggested to trial the developed rice lines in different regions of the country.
The BAURES director also urged Govt. giving kind attention to these high yielding inbreed rice lines and take initiatives to release and distribute these rice varieties among the farmer of whole country.
At the end Dr Shahin said- since 1999 he has been doing research with his own funding without taking any financial support from Govt. or donors. For the last two years Biotechnologist Anisar Rahman has been working with him as co-researcher and the villagers of Hatibanda, Gabtoli, Bogra have been assisting Dr Shahin by giving opportunity to use their fields for research and seed production, cultivation of newly invented rice varieties.
The researcher draws attention and co-operation to the Govt. and other national and international organizations as his rice research activities have increased.
He urged the Govt. to include the rice lines or varieties to the national resource after patenting by genome sequencing.
The researcher, however, hoped that this will help to promote future rice research and will enrich the agriculture and the national economy.
Dr Md. Nazmul Haque Shahin born at Hona village in Comilla. He got PhD from Bangladesh Agricultural University (BAU), Mymensingh and post doctorate from Kochi University, Japan. He also served different agricultural research organizations in the country. Dr Shahin, a cultural activist, organizer, poet, novelist, dramatist, painter and also a short film director.
