    Studies on inter-racial and intra-racial F2 hybrids of Oryza sativa Linn.
    (Division of Agricultural Botany, Agricultural College and Research Institute, Vellayani, 1968) Rajendran, P G; Namboodiri, K M N
    A study on the F2 generation of inter-racial, (Vellayani-1 x Tainan-3) and intra-racial (Vellayani-1 x Taichung Native-1) rice hybrids of both direct and reciprocal combinations of crosses, with reference to the mode of inheritance of 15 plant characters , has been conducted during October to January 1968. Based on the results the following conclusions have been drawn. In both inter -racial and intra - racial hybrids , plant height, number of productive as well as non-productive tillers, flowering duration, exsertion and length of panicle, grain and straw yields, length , breadthand thickness of grains are inherited as quantitative characters controlled either by multiple genes or by one or two major genes and a few minor genes . No reciprocal difference in either of the two racial groups, is observed. Transgressive segregation is seen in all cases.
