Description:
|
A population consisting of 150 F2 was developed from a cross of two early maturing inbred lines, H 77/833-2 and PRLT 2/89-33. H 77/833-2 (H77) is the male parent of a number of thermotolerant, extra-early, high-tillering and high-yielding pearl millet hybrids, including HHB 67 (843A X H 77/833-2), which is widely cultivated in the Thar desert margins of northwestern India. PRLT 2/89-33 (PRLT) is an inbred derived from the ICRISAT Bold Seeded Early Composite (BSEC). BSEC is an elite breeding population based predominantly on Iniadi landrace germplasm from West Africa. Compared to northwestern Indian germplasm such as H77, Iniadi germplasm has fewer basal and nodal tillers, larger seeds, thicker stems and panicles, and broader leaves. A linkage map consisting of 50 RFLP markers comprises seven linkage groups and covers 352 cM with an average map distance between loci of about 7 cM. The marker and map data are kindly provided by Dr. R. S. Yadav. |
