Pulses are dried seeds of grain legumes, which fix atmospheric nitrogen, making them an environmentally friendly crop. In pulses, carbohydrates (50 - 65%) are the predominant storage constituent, followed by protein (18 - 30%), minor quantities of lipids, vitamins and minerals. Saskatchewan is the major pulse crop producer in Canada. At present, peas, lentils, dry beans and chickpeas are the four major pulse crops grown in Canada. However, with the changing demographics, there is a growing demand for other pulse crops in Canada. Mung bean is a pulse that is consumed as sprouts in oriental cuisine to soups and stews and dhal. The Canadian imports of Mung beans has doubled from $2 million in 2001 to around $5 million in the last decade and half. With a growing south Asian population the demand is expected to grow. Pulses are also considered as healthy foods especially for vegetarians for whom it serves as major protein source. Pulse proteins contain less methionine, but are rich in lysine, an essential amino acid deficient in cereal grains. The major pulse storage carbohydrate is starch, which has higher amount of amylose compared to cereal starch, that makes pulse starch less digestible. Pulse seeds also have high amount of complex carbohydrates that form the dietary fiber. Mung bean is a small-seeded, short duration and warm season legume crop. There have been some studies in Canada to grow Mung beans. The proposed research project will assess a mini core collection (290 genotypes) to identify very early maturing genotypes amenable to be grown in Saskatchewan and western Canada. The genotypes will be grown at two locations in Saskatchewan, around Regina and Tisdale in plots provided by Hanfood group holding corp. The genotypes will be assessed for agronomic traits and seed quality such as carbohydrates, proteins, dietary fiber and other selected micro-nutrients. Successful completion of this project will identify, early maturing genotypes suitable for Canadian conditions. Mung bean can be added as a new pulse crop for Canadian producers to meet the growing demand of Canadian consumers, and open up additional international markets.

豆类是豆科植物的干燥种子，可以固定大气中的氮，使其成为一种环境友好的作物。在豆类中，碳水化合物（50 - 65%）是主要的储存成分，其次是蛋白质（18 - 30%），少量的脂质，维生素和矿物质。萨斯喀彻温省是加拿大主要的豆类作物生产地。目前，豌豆、扁豆、干豆和鹰嘴豆是加拿大种植的四种主要豆类作物。然而，随着人口结构的变化，加拿大对其他豆类作物的需求不断增长。绿豆是一种豆类，在东方菜肴中作为豆芽食用，可用于汤、炖菜和印度豆。在过去的15年里，加拿大进口的绿豆从2001年的200万美元增加到500万美元左右。随着南亚人口的增长，预计需求将增长。豆类也被认为是健康食品，特别是对于素食主义者来说，它是主要的蛋白质来源。豆类蛋白质含有较少的蛋氨酸，但富含赖氨酸，这是谷物中缺乏的一种必需氨基酸。豆类贮藏碳水化合物主要是淀粉，与谷物淀粉相比，淀粉具有更高的直链淀粉含量，这使得豆类淀粉不易消化。豆类种子也有大量的复合碳水化合物，形成膳食纤维。绿豆是一种小粒、短生育期、暖季的豆科作物。在加拿大有一些种植绿豆的研究。拟议的研究项目将评估一个小型核心收集（290种基因型），以确定适合在萨斯喀彻温省和加拿大西部种植的极早熟基因型。这些基因型将在萨斯喀彻温省的两个地点，里贾纳和蒂斯代尔附近的汉福德集团控股公司提供的地块上种植。这些基因型将被评估的农艺性状和种子质量，如碳水化合物，蛋白质，膳食纤维和其他选定的微量营养素。该项目的成功完成将确定适合加拿大条件的早熟基因型。绿豆可以作为加拿大生产商的一种新的豆类作物，以满足加拿大消费者日益增长的需求，并开辟更多的国际市场。
