ABSTRACT
An experiment was carried out during 2009-2010 cropping season at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru to find out the performance of ICPA 2043 in A x B and A x R in producing seeds of ICPH 2671 in Alfisols and Vertisols, respectively as influenced by spacing during late sowing. The treatments composed of two row ratios (4:1 and 3:1) of male sterile (MS):male fertile (MF) lines; two row-to-row distances (60 cm and 120 cm); and two plant-to-plant spacings (40 cm and 50 cm). The research showed that the direct and interactive effect of row ratio and the different plant spacing did not influence the seed yield of ICPA 2043. Even though row ratio 4:1 with plant spacing of 60 cm x 40 cm produced more seed yield of ICPA 2043 for A x B (1,908.78 kg/ha) and ICPA 2043 for A x R (2,053 kg/ha), the difference was not significant among the other treatments.
