Aromatic Rice from Different Countries: An Overview

The present studies were carried out to characterize seventy-one aromatic rice germplasm from IGKV, Raipur. These germplasm were characterized and grouped on the basis of anthocyanin pigmentation, plant habit, and awning character. On the basis of pigmentation distribution in 10 plant parts, a total of twelve groups were formed with group one having no pigmentation and group twelve with pigmentation in 9 plant parts. On the basis of plant habit and awning character, three groups of each were formed. The genetic parameters for the ten agronomic traits indicated that the selection of genotypes may be done for fertile spikelets per panicle, spikelet density, spikelet sterility percentage, and hundred seed weight. Thus, on the basis of above characters, the genotypes Tulsi Mala, Baanspati, Ganga Balu, Samund Chini, Tulsi Amrit, Dudh Dhan, Kari Gilas, Shankar Jeera, and Jata Shankar may be selected for future study.

Grain Filling Stage

Based on the experiment of two inbred aromatic rice varieties and one hybrid aromatic rice line treated under four different temperatures( daymean temperature 21°C, 23°C, 26°C and 30°C respectively) during grain filling stage in phytotrons, the shape and arrangement of endosperm starch granules in rice grain transection were observed by scanning electron microscope and the related characteristics of rice grain qualities of chalky percent and chalkiness were analyzed at the same time. The results showed that under the lower temperature( daymean temperature21°C and 23°C), many large compound starch granules with clear angulars packed together regularly without significant natural gaps bewteen starch granules in the tansectional endosperm. However, with the increase of temperature, starch granules in the transectional endosperm were changed from regularly shaped and closely and orderly arranged to various shaped and chaoticly arranged with obvious natural gaps between starch granules, which was closely consistent with the poorer appearance quality under the higher temperature, which indicated that the endosperm structure is closely related with appearance quality of aromatic rice.

Rice Varieties

Integrated use of organic and inorganic fertilizers can improve crop productivity and sustain soil health and fertility. To gain insights into the response of green manure and chemical fertilizer, the present study was conducted to evaluate the growth, yield and proximate composition of aromatic rice varieties in Aman season at the research farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from July to December 2014. The experiment was set up in split-plot design with three aromatic rice varieties in main plots and six fertilizer levels in subplots. ‘Raniselute’ variety produced the highest plant height, dry matter weight hill-1, straw yield (7.81 t ha-1), biological yield (9.05 t ha-1), ash (1.59%), and fat content (2.81%). ‘BRRI dhan34’ gave the maximum number of effective tillers hill-1 (12.74), panicle length (27.93 cm), number of filled grains panicle-1 (192.5), 1,000-grain weight (17.22 g), grain yield (2.26 t ha-1), harvest index (29.99%), and carbohydrate content (77.63%). Application of 80% recommended doses of NPKSZn + green manure 3.5 t ha-1 showed better performance for getting the maximum growth, yield components and yield compared to other treatments. Recommended doses of NPKSZn showed the highest carbohydrate content (77.63%) and lowest moisture (8.75%) and ash content (1.29%). The maximum fat content (3.07%) and minimum carbohydrate content (76.53%) was obtained from 60% recommended doses of NPKSZn + green manure 7 t ha-1. Application of 20 and 40% recommended doses of NPKSZn + green manure 14 and 10.5 t ha-1 produced the highest moisture content (10.43%) and lowest protein content (8.26%) in rice grain. Green manure 17.5 t ha-1 produced the highest ash (1.79%), protein content (9.06%) and lowest fat content (2.51%).
