Seed vigor testing is an important component of quality control programs adopted by seed industry. The software Seed Vigor Imaging System (SVIS) has been successfully used for seed vigor assessment in different species. The objective of this research was to verify the SVIS efficiency to assess okra seed vigor in comparison to other vigor tests used for this species. Five seed lots of 'Clemson Americano' and four of 'Santa Cruz' were submitted to germination (speed and percentage), cold germination (speed and percentage), traditional and saturated salt accelerated aging (41 ºC/72 and 96 h) and seedling emergence tests during 12 months storage. Vigor index, uniformity of growth and seedling length were determined by the software Seed Vigor Imaging System (SVIS). Results showed that the vigor index and seedling length determined by the SVIS analyses are efficient to determine okra seed vigor as well as the accelerated aging test (41 ºC/72 h).

Heterosis is a solitary means of exploiting hybrid vigor in crop plants. Given its yield advantage and economic importance, several hybrids in rice have been commercialized in more than 40 countries, which has created a huge seed industry worldwide. India has made commendable progress and commercialized 117 three-line indica hybrids for different ecology and duration (115–150 days), which accounted for 6.8% of total rice area in the country. Besides, several indigenous CMS lines developed in diversified genetic and cytoplasmic backgrounds are being utilized in hybrid rice breeding. NRRI, which has been pioneering to start with the technology, has developed three popular rice hybrids, viz., Ajay, Rajalaxmi, and CR Dhan 701 for irrigated-shallow lowland ecosystem. Biotechnological intervention has supplemented immensely in excavating desirable genomic regions and their deployment for further genetic enhancement and sustainability in rice hybrids. Besides, hybrid seed production creates additional job opportunity (100–105 more-man days) and comparatively more net income (70% more than production cost) than HYVs. Hence, this technology has great scope for further enhancement in per se rice productivity and livelihood of the nation.
