BPT Rice 2841 is a black rice variety developed through a three-way cross involving MTU 7029 (Swarna), IRGC 18,195 and MTU 1081. BPT Rice 2841 is a high-yielding, non-lodging, semi-dwarf black rice variety suitable for the Kharif season in the Krishna Zone of Andhra Pradesh, Unlike other glutinous black rice varieties, BPT Rice 2841 has an intermediate amylose content of 23.4% and an alkali spreading value of 4.5, ensuring its grains cook to a soft and flaky consistency, suitable for raw rice and can be included in daily diet consumption. Its black pericarp endows it with potent antioxidant activity (110.5 mgAAE/100 g) and a flavonoid content of 582.6 mgQE/100 g, contributing to neutralizing free radicals and bolstering human immunity. Furthermore, it registered a 36.75% slowly digestible starch content and a glycemic index of 62.5, categorized as medium GI. Notably, the unpolished BPT 2841 rice contains 24.3 ppm of zinc, 15.6 ppm of iron, and 11.2% protein, making it nutritionally superior to white rice and aiding in addressing malnutrition concerns. The textural properties of BPT 2841, characterized by lower stickiness, springiness, cohesiveness, gumminess, and hardness, make it highly suitable for raw rice with consumer acceptance.
BPT水稻2841是通过三交培育出的黑米品种,涉及MTU 7029(斯瓦纳)、国际水稻遗传资源中心编号18195以及MTU 1081。BPT水稻2841是一种高产、抗倒伏的半矮秆黑米品种,适合安得拉邦克里希纳地区的雨季种植。与其他糯性黑米品种不同,BPT水稻2841的直链淀粉含量为中等水平,为23.4%,碱消值为4.5,这使得其米粒煮后质地柔软且呈片状,适合作为糙米食用,可纳入日常饮食。其黑色果皮赋予它强大的抗氧化活性(110.5毫克抗坏血酸当量/100克)和582.6毫克槲皮素当量/100克的类黄酮含量,有助于中和自由基并增强人体免疫力。此外,它的慢消化淀粉含量为36.75%,血糖生成指数为62.5,属于中等血糖生成指数类别。值得注意的是,未加工的BPT 2841大米含有24.3 ppm的锌、15.6 ppm的铁和11.2%的蛋白质,在营养方面优于白米,有助于解决营养不良问题。BPT 2841的质地特性表现为粘性、弹性、内聚性、胶粘性和硬度较低,这使其非常适合作为糙米,受到消费者认可。
