Abstract
Indian mustard [Brassica juncea (L.) Czern & Coss] is an important Rabi season oilseed crop, belongs to family Cruciferae and genus Brassica. Indian mustard is a natural amphidiploid (2n=36) a cross between Brassica rapa (2n=20) and Brassica nigra (2n=16). Mustard is largely self-pollinated but certain amount (2-14%) of cross pollination may take place and is mainly grown in northern part of India. Rajasthan contributes 44.60 % in area & 52.05 % in production of total rapeseed-mustard of India. Mustard crop required lower water requirement (240–400 mm) for completing life cycle, therefore it is fits well for rain fed cropping systems. Four oleiferous brassica species viz. Brassica juncea, Brassica napus, Brassica rapa and Brassica carinata are cultivated in about 6.2 International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 10 (2020) Journal homepage: http://www.ijcmas.com
印度芥菜[芥菜]是一种重要的Rabi季节油料作物，属于十字花科和芸苔属。印度芥菜是天然的双二倍体(2n=36)，是油菜(2n=20)和黑油菜(2n=16)的杂交品种。芥菜大部分是自花授粉，但也有一定数量(2-14%)的异花授粉，主要种植在印度北部。拉贾斯坦邦贡献了44.60%的面积和52.05%的印度油菜籽-芥菜总产量。芥菜作物完成整个生命周期所需水量较低(240-400毫米)，因此非常适合雨养种植系统。《国际微生物学与应用科学杂志》(International Journal of Current Microbiology and Applied Sciences, ISSN: 2319-7706 vol . 9 no . 10(2020))期刊首页:http://www.ijcmas.com)约6.2种油菜(brassica juncea)、油菜(brassica napus)、油菜(brassica rapa)和油菜(brassica carinata)
