| Popis: | Twenty popular rice varieties developed by ANGRAU obtained from Regional Agricultural Research Station (RARS), Maruteru during Kharif – 2019, were screened for chemical quality traits viz., gel consistency, gelatinization temperature, amylose along with glycemic index.In our study, significant variation was observed among all the varieties for chemical traits but no significant variation was observed in case of glycemic index.The amylose content observed over the varieties ranged from 21.7 per cent to 24.73 per cent. All the varieties have intermediate amylose content. Gel consistency ranged from 37.67 (hard gel) to 75 (soft gel) with the mean of 52.57. The alkali spreading value was noticed to be low, intermediate and high among all rice varieties.Glycemic index rangedfrom 56.72 -66.43 with a general mean of 60.67. Furthermore, all the varieties were categorized as medium GI varieties (56-69). Among all the varieties, Pushyami has shown the least value (56.72) for glycemic index.From the present investigation, it is concluded that, Rice varieties such as Chandra, Indra, Sri Dhruthi, Swarna, Samba Mahsuri, Sujatha, Maruteru Samba, MaruteruMahsuri recorded intermediate amylose, alkali spreading value and medium GI, which are desirable for rice consumers while counting for better rice with the best quality and glycemic index. |
