Abstract
HYBRID v+gor in sorghum(s)” has been the title of three papers (1, 2, 3) and has been discussed in some detail in several others. Early examples of “maximum vigor” ( 3 ) expressed in extreme height and lateness and heavy forage yield have been largely accounted for by the effects of a relatively few complementary genes for elongation and for number of internodes (4, 5, 6 ) . In some crosses earliness is dominant or partly dominant to lateness (6), although to what extent this is generally the effect of one or a relatively few genes and to what extent an expression of hybrid vigor has not beeh determined. If the parents of an F, intermediate in maturity carry the same height factors, the hybrid is intermediate in height due to a shorter growing period than that of the later parent. For grain production under present farm practices this type of hybrid is of more interest than the hybrids with “maximum vigor” because the trend during the past decade has been toward quick-maturing and shortstalked varieties that are more likely to escape drought, frost, and other hazards.............
