Abstract:

Pattern of segregation and performance of selected F5 individuals were studied in 21 different F5 families which were derived from eight crosses in rice. Pattern of segregations in different F5 populations revealed moderate to wide range of genetic variation with respect to grain yield and yield components as well as other quantitative characters. In the cross KS × IE2, recombinants with semi-dwarf plant height with greater panicle length, good percentage of filled grain, higher secondary branches and yield were selected where the semi dwarf plant height was inherited from IET 14142 genotype which was a true breeding mutant having short plant height. In the cross SNT × KS, segregants with long slender and bold grains, semi-dwarf to tall plant heights and sturdy culm were obtained. In the cross SNT × IE2, the long slender grain found in most of the recombinants is one of the important characteristics of Shantibhog and the semi-dwarf height of segregants was contributed by the true breeding mutant of Tulaipanji, IET 141. In the cross STB × IE3, three segregants from each of the two families and one from another family were selected as they showed considerable variation for plant height, grain number as well as yield. In the cross IE2 × SS, recombinants with good grain yield, medium grain number with intermediate grain dimensions were found. Awns with variable expressivity was noticed under field condition which was contributed by the IET14142 parent.
