Abstract

Rice is an edible starchy cereal grain. Large part of the world population depends on rice for their daily carbohydrate needs. Locally cultivated rice landraces are excellent source for protein, fibre and ash. But nutritional studies in these landraces were abended in earlier days due to emphasis on developing high yielding new rice varieties and most of the landraces were long duration in nature (> 145 days) as compared to varieties (110 – 130 days).In this study an experiment was conducted to study the nutritional properties viz., grain protein content, crude fibre and ash content in 60 native rice landraces. The standard methods developed by AOAC (2000) were followed in proximate analysis in rice grains. Analysis of variance and variability studies revealed that high variability between the genotypes for all three characters. High PCV, GCV and high heritability (h2) coupled with high genetic advance as percentage of mean (GAM) indicates that these characters are more influenced b

Conclusion

The results obtained from this study suggested that nutritional characterization of 60 landraces based on grain protein content, crude fibre and ash content exhibited considerable variation among these genotypes. Grain protein and crude fibre content are the major concern as rice nutritional properties. Majority of the entries studied registered high grain protein, moderate fibre and moderate ash content. The genotypes Kattu vanipam, Poongar, Palkichadi, Karuppu Kavuni, Kaivara samba, Barma Kavuni, Lalmati and Sivappu malli registered high grain protein along with high crude fibre and ash content. Since, these genotypes exhibited superiority in all three characters they can be used in breeding programmes for the development of varieties with high nutritive values. The availability of nutritional information in case of locally cultivated landraces is minimum the results obtained in this study enriches the nutritional data base of landraces. This available information can also be utilize
