Heterosis in relation to genetic divergence and specific combining ability in groundnut (Arachis hypogaea L.)
SummaryThe frequency and magnitude of heterosis were examined in relation to genetic divergence among parents in two diallel cross experiments in groundnut. The parents were grouped into clustersExpand

The Fallacy Behind the Use of a Modified Line × Tester Design
The genetic models governing a line × tester design and a modified design in which the parents are included are examined in detail. The errors involved in the procedure of analysis followed byExpand

Limits To Genetic Divergence For Occurrence of Heterosis -Experimental Evidence From Crop Plants
Two experiments in groundnut (Arachis hypogaea L.) and one in rapeseed (Brassica campestris L.) involving varying number of crosses made to diailel and line × tester designs were studied with the aimExpand

Are ‘multiple cross-multiple pollen hybrids’ an answer for productive populations in Brassica campestris (var.) Brown Sarson?
SummaryA set of 167 ‘mucromphs’ was evaluated in their F1 generation for seven ‘plant’, four ‘plot’ and five ‘ratio’ characters. Methods of characterizing the parents and the hybrids on the basis ofExpand

A Study on the nature of genetic divergence in rice from assam and North East Himalayas
SummaryA representative group of 190 rice types collected from North-East India along with four standard varieties, three of which were indicas and one japonica, was studied to understand the natureExpand

Evaluation of diallel crosses by graphical and combining ability methods
The genetic models behind two approaches, graphical analysis due to Jinks and Hayman and combining ability analysis due to Griffing, employed in the analysis of data from diallel crosses are reviewedExpand
