Distribution of allelic variation for genes of vernalization and photoperiod among wheat cultivars from 23 countries
(Institute of Crop Sciences, 2011)
Molecular markers for vernalization genes Vrn-A1, Vrn-B1, Vrn-D1 and Vrn-B3 and photoperiod gene Ppd-D1 were used to detect the presence of these genes among 755 cultivars from 23 countries. Days to heading and physiological ...

Seedling and slow rusting resistances to leaf rust in CIMMYT wheat lines
(Institute of Crop Sciences, 2011)
CIMMYT wheat has played an important role in wheat breeding in China. Identification of leaf rust resistance genes in CIMMYT wheat is important for developing wheat cultivars with resistance to leaf rust in China. A total ...

Effect of nitrogen fertiliser applied to tef on the yield and N response of succeeding tef and durum wheat on a highland vertisol
(African Crop Science Society, 1999)
A trial was conducted on an Ethiopian Vertisol from 1990 to 1995 to determine the residual effect of fertiliser N applied to tef (Eragrostis tef) following chickpea (Cicer arietinum) on the grain and straw yield, N content, ...

Heterosis and combining ability of CIMMYT's tropical late white maize germplasm
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 1992)
Seven tropically adepted, late maturity maize gene pools and populations (Populations 21, 22, 25, 29, 32 and 43, and Pool 24) developed and improved at CIMMYT were crossed in a 7 x 7 diallel mating system. The parent and ...
