Are "multiple cross-multiple pollen hybrids' an answer for productive populations in Brassica campestris var. 'brown sarson'? : I. Methods for studying 'mucromphs'.

A set of complex crosses with multiple crosses as female parents were made using multiple pollen in turnip rape (Brassica campestris L.). These multiple cross - multiple pollen hybrids (mucromphs) were evaluated for a large number of quantitative characters including yield. New methods were proposed to study such genetic material in depth so as to formulate suitable strategies to breed for attractive seed yield.
