Abstract

The present study was aimed to conceptualize heterosis for response to supplement yield by utilizing Nitrogenous fertilizers more efficiently. Genotypic diversity for response towards patterns of agronomical management and diversity based on morphological characters was assessed to find out promising parents in order to select promising segregants. Out of 10 pairs thus obtained, progenies of only two crosses Pusa Basmati1xType3 and P1121xType3 provided desirable segregants. The segregating population was screened following pedigree method in order to get basmati type plants with better gene recombination. Uniform bulks of F5 and/ F6 generations were evaluated for response to different levels of fertilizers, diseases reactions, lodging resistance and parameters of quality. Disease severity % and AUDPC (Area Under Disease Progress Curve) parameters and adequate biotechnological tools were used for screening blast resistance. Better types were finally evaluated in station trials as well before evaluation in statutory multitier trials co-ordinated by ICAR (Indian Council of Agriculture Research). Data of such trials were used to validate the supposition of heterosis of response. The study revealed that this technique could substantiate benefits to the farmers.
