Abstract:
Experiments were conducted at Chaudhary Charan Singh Haryana Agricultural University, Hisar, India during the Kharif season to evaluate segregating Pusa 1121 (Basmati) x MAS25 (aerobic) F₅ and MASARB25 (aerobic) x Pusa Basmati 1460 (Basmati) F₄ populations for various physio-morphological and/or root traits and allelic diversity for BAD2 (aroma) gene and microsatellite markers linked to the traits promoting aerobic adaptation. In both populations, enormous variation was observed for plant height, panicle length, and effective number of tillers per plant, root length, root thickness, fresh and dry root weight, 1000 grain weight, grain length/breadth ratio and yield per plant. A number of promising F₄ and F₅ plants have been selected, which had higher grain yield, root length and biomass greater than MAS25 and MASARB25 and Basmati specific allele at BAD2 locus (either in homozygous or heterozygous condition) for further progeny analysis.
