Abstract
A study was conducted to assess the performance of rice hybrid and other varieties planted in rice growing areas of Sindh and Balochistan during the year 2008-2009. For this purpose primary data were collected from randomly selected 100 rice growers. The farm cost analysis and gross margin analysis was carried out. The results revealed that average yield of hybrid rice was 195 mds/hectare, followed by IRRI-6 (151 mds/hectare), B-2000 (91 mds/hectare) and Rosi (94 mds/hectare). This indicates that the yield of hybrid rice was higher by 29 percent than the major variety IRRI-6. However, the growers received low price by Rs. 8/mds for hybrid rice against IRRI-6 variety. The main reasons for low price was reported as poor grain quality i.e. high percentage of broken rice and variation in the grain size. This study concludes that overall growers earned more profit by adopting hybrid seed technology but there are some repercussions of this technology such as, growers have to buy costly seed every year and have to depend on seed companies. Additionally there is a loss of age-old knowledge and tradition of seed production that sustained rice farming from centuries. As the seed is a basic resource for crop production. Moreover, all stakeholders are in the hands of monopolistic seed corporations.
