Identification And Characterization

Identification and characterization of crop varieties are crucial for ensuring the genetic purity of seeds. The present investigation was carried out to identify suitable chemical methods that are fast, reliable and easy for seed analysts, breeders and seed producers for identification of a variety. Twenty-five popular rice varieties in the seed supply chain of Tamil Nadu were subjected to phenol, modified phenol, NaOH, aroma, gelatinization temperature (alkali spreading value), GA3 and 2,4-D tests. The results of the experiment revealed that phenol and modified phenol tests changed the colour of TKM 9 and TRY 1 variety to brown but no colour change was observed in the variety I.W. Ponni variety. The NaOH test is useful for the identification of TKM 9 variety as it changed the colourless solution to red. GA3 and 2,4-D tests characterized the varieties based on the shoot growth into two and three groups respectively. However, all the variety lacked aroma and exhibited a high gelatinization temperature.

Rice (Oryza sativa L.) which belongs to the family poaceae, is the life and the prince among cereals as this unique grain helps to sustain two thirds of the world's population. India have traditionally been used or rice cultivation due to availability of water and conductive soil (Nadesa panic). Rice was grown in 155.30 million hectares and around 600 million tonnes of rice harvested each year globally. About 114 countries produce rice with China and India supporting 50 per cent of total production. India stands first in area under cultivation (41.85 mha) and ranks second in production, where as China ranks first in production with just half of the area. India's production is 89.13 million tonnes with a productivity of 2130 kg/ha. Among the rice producing states of India, Tamil Nadu ranks sixth in production (6.53 million tonnes) and second in productivity of 3918 kg/ha with an area of 20.16 lakh ha (Season and Crop Report, 2012). Local farmers in such farming systems retain the traditional varieties based on their knowledge of the quality of the rice varieties and their adaptation to varying agro-ecological situations created by diverse seasons and land situations (Tapasi das & Ashesh Kumar Das, 2014). Among the major micronutrient deficiencies common in rice consuming countries, iron and zinc deficiencies (“hidden hunger”), affect over three billion people worldwide, mostly in developing countries (Welch & Graham, 2004).

For any crop improvement program, it is imperative to assess the grain yield progress of the existing crop varieties to find the further avenue to out yield the existing superior ones. Therefore, an experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from July to December 2013 to find out the genetic variation for grain yield and their associated traits of transplant Aman rice varieties. The experiment consisted of 11 varieties viz. Bashiraj, Binadhan-7, BR10, BR11, BR22, BR23, BRRIdhan32, BRRIdhan39, BRRIdhan49, BRRIdhan57 and IR64. The high yielding Bangladeshi varieties were selected based on their releasing year with a local and one exotic T. Aman rice varieties. Among the varieties, BR10 produced the highest grain yield (3.83 t ha-1). Binadhan-7 rice variety recorded the highest chlorophyll content (39.93 SPAD value) at 29DAT, (44 SPAD value) at 39 DAT and (47.30 SPAD value) at 49 DAT. The highest phenotypic (1491.81) and genotypic (1147.26) variances and genetic advance (61.19) were obtained from spikelets panicle-1 and this parameter had greater ability to increase yield. Among the traits, the highest heritability was recorded by effective tillers hill-1 (87.91%) which influenced the grain yield. Therefore, it may be concluded that the variety BR10 of transplant Aman rice produced maximum grain yield, spikelets panicle-1, showed high phenotypic and genotypic variances and genetic advance. Bashiraj, BRRIdhan49 and BRRIdhan57 also can be considered as planting materials as their yield performance is close to BR 10. Therefore, the findings of the present study will help the breeders for further yield improvement of rice.Res. Agric., Livest. Fish.2(2): 207-213, August 2015
