Purpose of Description

ICSV 145 was recommended in 1987 by the All India Coordinated Sorghum Improvement Project (AICSIP) for cultivation in Striga-endemic orghumgrowingareas of India. It has been specifically bred for resistance to the white-flowered strain of Striga asiatica that occurs in India.

Origin and Development

ICSV 145 is a pure line variety selected from a cross between IS 18475 (555), a low stimulant producer that is resistant to S. asiatica and IS 18468 (168), a high-yielding adapted variety released in India as CSV 5 . The succeeding segregating (F2-F6) generations of this cross were sown in Striga-sick fields at ICRISAT Center (Patancheru), Akola, Bijapur, and Bhavanisagar in India, making it possible to select Striga-resistant single plants with desirable agronomic traits. The selection No. 1-1 which appeared to be uniform across locations was named as SAR 1 in 1981. ICSV 145 was tested in AICSIPadvance Striga trials as SPV 694 from 1982 to 1986 and was found to be highly resistant to Striga and to produce high grain yields in the Striga-sickfields (Table 1). In 1984, it was recommended for farmers' field testing particularly in Striga-endemic areas in the Indian states of Maharashtra, Andhra Pradesh, and Karnataka. ICSV 145 was recommended in 1987 for cultivation in the Striga-endemic areas of India.
