To Identify and Select Superior M3 Progenies and Estimate the Magnitude of Various Genetic Parameters in Respect of Yield and Yield Attributes in Guar [Cyamopsis tetragonoloba (L.) Taub.]

A study was conducted during Kharif 2002 to assess induced variation among 131 (80 selected and 51 bulk) M₃ progenies of guar variety RGC-197 in respect of yield and yield attributes. Analysis of variance revealed significant differences between the progenies and non-significant differences within the progenies for all the characters studied. Based on 't' test, a considerable number of M₃ progenies were significantly different for their mean values from the parent RGC - 197 in respect of all the traits. Progenies, showing significantly lower values of a trait were more frequent than those showing superior values than the control except for 100- seed weight. Variations in respect of various characters were induced to different magnitudes. Based on significantly higher mean values than control and bulk progenies, five selected progenies namely 31-7, 41-6, 78-2, 81-6 and 128-5 were identified as superior ones. The characters viz., plant height, seed yield per plant, pods per plant and 100- seed weight were relatively more heritable than the other character studied.
