 Business misuse of half and half power is a standout among the most imperative uses of hereditary qualities in agribusiness. It has added to sustenance security, as well as profited the earth (Duvick 1999). It is the premise of a billion-dollar agribusiness which has produced huge livelihood openings everywhere throughout the world. Among the different yield species in which half breed assortments are utilized financially, rice positions high. Rice half and halves were initially popularized in the late 1970s in China. Amid the previous decade, Vietnam, India, the Philippines, Bangladesh and the United States have additionally started the business generation of half and half rice.

Around 15 million ha (half) of rice in China are mixture assortments, delivering 103.5 million mt of paddy every year (a normal yield of 6.9 mt/ha). The staying half, planted in ingrained high-yielding rice assortments, produces 81 million mt (5.4 mt/ha). In this manner, all things considered cross breed rices in China yield around 27% (1.5 mt/ha) more than the innate high-yielding assortments.

The commercialization of half and half rice innovation in tropical nations has been encouraged by the exploration started in 1979 at the International Rice Research Institute (IRRI). It was soon perceived that Chinese rice half breeds were not suited to the tropics, and their grain quality was poor contrasted with the prominent ingrained high-yielding assortments developed in tropical nations. Consequently, IRRI scientists focused on creating appropriate parental lines exceptionally for the tropics, utilizing the CMS framework which had been observed to be viable in China.

Inside 10 years, some financially usable CMS and restorer lines and some first class cross breeds were distinguished and imparted to NARS for assessment and usage. Some of these mixtures were discharged for business development in the Philippines (IR64616H, IR68284H), India (IR64611H, IR64618H, IR69690H), Vietnam (IR64615H, IR64616H, IR69690H) in the years 1993-1998. Some IRRI CMS lines, IR58025A and IR62829A, were additionally utilized by national projects to create nearby half and halves in India (e.g. APHR-1, APHR-2, CORH 2, KRH 2, ADTRH 1, and so on) and the Philippines. Simultaneously, a few private seed organizations in Asia were likewise furnished with IRRI-reproduced parental lines.

At present, around 610,000 ha are secured with crossover rices in Vietnam (340,000 ha), India (200,000 ha), Bangladesh (50,000 ha), USA (10,000 ha), Philippines (5,000 ha) and Myanmar (5,000 ha). These have given all things considered around 20-25% (1 - 1.5/ha) higher yields than the ingrained HYVs, in this manner contributing towards higher on-homestead profitability. Right now, half and half rice innovation is viewed as a suitable alternative to build rice yields all inclusive (Yuan 1994, Virmani 1994, Janaiah and Hossain 2000). Since rice is a self-pollinated edit, crossover seed generation must be founded on male sterility frameworks. These might be cytoplasmic (CMS), thermo-delicate genic (TGMS) or photograph touchy genic (PGMS). A large portion of the business cross breeds utilized as a part of China and somewhere else depend on a CMS framework, in spite of the fact that TGMS and PGMS frameworks are likewise getting to be utilized economically (Yuan, pers. comm.). Cross breed seed generation innovation including these male sterility frameworks is mind boggling and work serious. It additionally requires an advanced seed industry framework.

This Bulletin portrays the innovation for half and half rice seed generation, its monetary feasibility and effect on ranchers and the seed business, and its provincial occupation oppor-tunities. Open doors for vegetative proliferation in cross breed rice development are likewise talked about.


Day by day Hybrid rice seed production in Bangladesh are increasing to ensure food security.


There is no specific SCA standard for hybrid rice seed like inbred in Bangladesh.

  1. It's a very important for ensuring food security. But it is only reference and statistic. So required methodology, how to produce seed to seed.
