Registration of 'ICMV-IS 88102' Pearl Millet

' ICMV-IS 88102' pearl millet [Pennisetum glaucum (L.) R . Br.](Reg. no. CV-12, P1586660) was developed for food grain produc-tion by the International Crops Research Institute for the Semi-AridTropics (ICRISAT) and the Institut d'Etudes et de RecherchesAgricoles (INERA) at the Agricultural Research Station at Kam-boinse, near Ouagadougou, Burkina Faso. Both INERA and theInstitut d'Economie Rurale (IER) in Mali conducted on-station andon-farm evaluations of ICMV-IS 88102. ICMV-IS 88102 wasreleased by INERA in 1993 to farmers in Burkina Faso. In 1994,IE R released ICMV-IS 88102 to farmers in Mali under the nam e'Benkadi N io', which me ans 'friendship millet' in the local

Bamanan language.ICMV-IS 88102, an open-pollinated cultivar, w as developedfrom germplasm accession IP 6426 (P436) from Mali. Two hun-dred an d seventy-three accessions supplied by the Genetic Resourc-es Division at ICRISAT Center, Hyderabad, India, were evaluatedat the INERA station at Farakoba, Burkina Faso, in 1986, and IP6426 was retained for further evaluation. IP 6426 was sown at theINER A station at Kam boinse in the post-rainy season (N ov. 1986to Feb. 1987), and 47 selected selfed plants were harvested sepa-rately. In the 1987 rainy season at Kam boinse, these 47 Si progenylines were evaluated for grain yield, desirable plant characteristics,

an d resistance to downy mildew [caused by Sclerospora gramin i -cola (Sacc.) J. Schr6t.]. Fourteen of the 47 Si lines of IP 6426were selected for intermating, based on visual assessments of agro-nomic worth. The 82 progenies from 5 to 6 of the best selfedplants in each of the selected Sj lines w ere harvested an d bulkedto produce 14 82 line bulks. Intermating of 82 progeny lines wasconducted at Kam boinse Station du ring the post-rainy season (N ov.1987 to Feb. 1988). Eight grams of seed of each of the 14 selected82 line bulks w as mixed an d planted to produce a population of ap-proximately 1000 plants. One hundred plants of each selected 82progeny line were planted separately, and plants were bagged at the

time of heading. Plants from each ind ividual 82 line were pollinat-ed w ith pollen collected from >25 plants from the 82 bulk popula-tion. A bulk was constituted by mixing 300 g of crossed seed har-vested from each of the 14 selected 82 lines. The bulk populationwas designated ICM V-IS 88102; it was multiplied during the 1989rainy season in an isolated field at Samanko, Mali .

ICM V-IS 88102 is recom men ded for cultivation in the 800- to1000-mm annual rainfa ll zone of Burk ina Faso and Ma li. ICM V-IS

gola in the Bamako region (approximately 900-mm rainfall zone)and 2 to 3 wk earlier than Sanyo-type local cultivars in theSouthern Sudanian Zone of Mali and Burkina Faso.

In trials conducted from 1988 to 1994 at five locations in the 800-to 1000-mm rainfall zone in Mali, average grain yield of ICMV-

IS 88102 at Samanko an d Sotuba was 2.721 ha~' (4 % higher thanthe local cultivar M agangola). In another set of trials at Samankoan d Sotuba, ICMV-IS 88102 yielded 2.45 t h a ~ ' (42% higher thanthe local cultivar Djiko); at Katibougou, 2.08 t ha "

1(21% higher

than the local cultivar Kati); at N'Tar la , 2.13 t ha- ' (2 % higherthan the local cultivar Tarla); and at Longorola, 1.911 ha ~' (59%higher than the local cultivar Sanko). In 11 on-farm trials conduct-ed in the 1992-1993 growing season in the Sou thern Segou regionof Mali, average grain yields of ICMV-IS 88102 and 'Souana'

were 2.40 and 1.80 t ha"1

, respe ctive ly. In the 800- to 1000-mmrainfall zone of B urkina Faso, average grain yield of ICM V-IS88102 at Saria was 1.83 t ha ~' (10% highe r than the local cultivarKapelga); at Farakoba, it was 1.65 t ha"

1(330% higher than the

local cultivar Farakoba, which matures 3 wk later and usuallysuffers terminal drought). In another set of trials at Farakoba,ICMV-IS 88102 yielded 2.65 t ha '

1(18% higher than 'M12' of

similar maturity).ICMV-IS 88102 is 3.1 to 3.6 m in height, with four to five

reproductive tillers. Earheads are 31 to 37 cm long, candle-shaped,and devoid of bristles. Grains are medium size (9 to 11 g 1000seed"1), globular, and light gray, with a vitreous endosperm. Thedowny mildew infection index fo r ICM V-IS 88102 in disease nur-series during 1992 to 1994 in Mali an d Burk ina Faso ranged from5 to 13%, compared with 18 to 71% for the susceptible check,ICMV-IS 91121. The taste and conservation quality of To mad efrom ICMV-IS 88102 was rated good by consumers.
