Abstract Traditional rice genotypes are valuable sources of diverse phenotypic traits. The Garos inhabiting Garo Hill Districts in Meghalaya conserve and grow numerous rice landraces. Yet the nutritive value which are pivotal trait of traditional rice genotypes remains grossly under investigated. Nutrient profiling of 32 rice landraces including 8 glutinous varieties as brown rice and their milled counterparts (5 and 10 % DoM) was carried out. Both non-glutinous and glutinous rice landraces showed mean protein content of 7.54 g/100 g (13 % c.v.), total fat 2.79 g/100 g (15 % c.v.), total dietary fiber 5.78 g/100 g (5% c.v.), ash 1.08 g/100 g (16 % c.v.) niacin 2.74 mg/100 g (23 % c.v.), pantothenic acid 2.08 mg/100 g (44 % c.v.), iron 1.28 mg/100 g (34 % c.v.), zinc 2.31 mg/100 g (16 % c.v.) and phytate 256 mg/100 g (1% c.v.). Rice landraces had significantly higher dietary fiber and lower phytate content as compared to contemporary varieties. There were no significant differences in the nutrient content between glutinous and non-glutinous genotypes. Milling resulted in substantial reduction of all nutrients even at 5% DoM and the loss was most profound for micronutrients. The substantial variability of nutrients that exist within these 32 Garo rice landraces can be used for nutrient improvement in rice

印度东北部梅加拉亚邦加罗山水稻地方品种的原位养分变异

摘要 传统水稻基因型是多种表型性状的宝贵来源。居住在梅加拉亚邦 Garo Hill 地区的 Garos 保护和种植了许多水稻地方品种。然而，作为传统水稻基因型关键性状的营养价值仍未得到充分研究。对 32 个水稻地方品种进行了营养分析，其中包括 8 个糯米品种，如糙米及其碾磨的对应物（5% 和 10% DoM）。非糯米和糯米地方品种均显示平均蛋白质含量为 7.54 g/100 g (13% cv)，总脂肪 2.79 g/100 g (15% cv)，总膳食纤维 5.78 g/100 g (5% cv) , 灰分 1.08 g/100 g (16% cv) 烟酸 2.74 mg/100 g (23% cv), 泛酸 2.08 mg/100 g (44% cv), 铁 1.28 mg/100 g (34% cv), 锌2.31 mg/100 g (16% cv) 和植酸盐 256 mg/100 g (1% cv)。与当代品种相比，地方水稻具有显着更高的膳食纤维和更低的植酸含量。糯和非糯基因型之间的营养成分没有显着差异。即使在 5% 的 DoM 下，碾磨也会导致所有营养素的大量减少，并且微量营养素的损失最为严重。这 32 个 Garo 水稻地方品种中存在的养分差异很大，可用于改善水稻的养分
