The university has the credit of evolving many improved varieties / hybrids that have benefited the farmers beyond the boundaries of the State and have equally rejuvenated the seed industry. The university has been the path setter in exploitation of hybrid technologies in cotton, castor and pigeonpea with all tools (conventional, genetic and cytoplasmic genetic male sterility) exploited at commercial scale. New varieties of the university have been indented from as far as Chhatishgadh and Jharkhand involving both public and private seed sector. Further the varieties have been evolved both in traditional and non-traditional crops.
The castor has attained two problems (i) wilt and nematode complex due to intensive agriculture and (ii) root rot in rainfed and drier areas. The very cultivation of the castor was at stake due to wilt-nematode complex in irrigated areas. The university has given a very productive and high oil content quality hybrid GCH 7 that is completely resistant to wilt-nematode complex. The resistance is durable as it involved both the parents as resistant wilt-nematode complex. Besides it has easier Grow Out Test that is so important in seed certification for identifying hybrids in initial stages. This has given a big fillip to the production and quality of castor; and has also made the soil healthier due check in wilt-nematode load built up. The hybrid has 10 percent yield advantage over the extant hybrids that accrue additional income in crores per annum. Similarly the other hybrid released for drier areas viz GCH 6 too is root rot resistant and has alleviated the problem of the rainfed areas. Needless to emphasize the hybrids released by this university has made their appearance in other castor growing States of the country and has equally benefited the farmers, seed industry and the industrialists. The quality and the value addition is being addressed precisely by evolving zero erucic acid hybrids besides work on quality aspects on oil derivatives. Over all consequent up on the technologies developed 82 per cent of the castor is produced in Gujarat with highest productivity that has evinced around five times increase during last two decades.
In mustard the dicey predicament in research was that the late varieties were bold seeded while the early varieties had smaller seed size. The early varieties are needed in arid areas due to lesser “LGP” (least growth period) but the industry requires bold seeded variety due to higher oil contents. The university has released variety GM 3 and GM 4 that have combined earliness and bold seeded and has got a good response from farmers and the industry.
The university has lately released three varieties viz., GDW 1255, GW 11 and GW 451. Out of these, GW 1255 is the quality durum wheat for irrigated areas in Gujarat having more than 15 per cent protein, 6.4 ppm ß carotene and no yellow berry incidence. The variety has quality standards as per international requirements. Another variety GW 11 is highly thermo-tolerant both at initial and terminal growth stages besides suitable for limited inputs including water. The GW 451 is yet another achievement of university in quality wheat as its grain is very attractive with higher grain yield.
