✦ Synopsis

Heterosis for yield and yield components were studied in F l , F 2 and F 3 generations in ten crosses of wheat, Triticum aestivum L ., under normal spacing . Eighty and 60 % F I hybrids exceeded the high parent and standard variety to the extent of 44 .3 and 36.4 per cent. respectively. The two best crosses excelled the high parent and the standard variety by a significant margin . The result showed that seed of advanced generations cannot be used for commercial wheat production, Heterosis in yield seems to be reflected through heterosis in spike number and 1000-kernel weight . In general it was found that the greater the genetic difference of the parents with a high yield capacity the better are their hybrids .

To discuss the utilisation of heterosis in plant breeding it is necessary to consider its genetic basis . In cross fertilized plants in which the phenomenon of heterosis is very important, such as maize, it appears that a great part can be explained by the mutation load . However in both autogamous

In a three-year period 48 spring wheat Fi's and seven FZ's and F3's which had shown heterosis for yield in the F1 were studied for yield and quality. The main conclusion is that the sharpest rise in yield of the F1 is manifested by crossing high yielding varieties which differ in origin and agronomi
