STABILITY FOR PHYSIOLOGICAL MATURITY AND KERNEL YIELD OVER LOCATIONS IN MAIZE (ZEA-MAYS L) GENOTYPES

Ten composite varieties of maize were evaluated for stability of physi ological maturity and kernel yield at five different locations viz. Jo ydebpur, Jamalpur, Jessore, Ishurdi and Hathazari during rabi season. Genotype-location interactions were observed for both the characters. Except three, all early and rate genotypes were average in response (b (i) similar or equal to 1) and stable (S(2)b(i) similar or equal to 0) over locations for physiological maturity. The highest yielding genot ype Guayabal Aragua 4843 with above average stability (b(i) <1) and mi nimum deviation (S(2)d(i) similar or equal to Of was the least respons ive entry and found suitable for low-yielding environment. Camayagua 8 528 and Across 8536 with P > ($) over bar x and minimum deviations had below average stability (b(i) >1) and could be considered suitable fo r high-yielding environment. Capinopolis 8645 RE, with P > ($) over ba r x, b(i) similar or equal to 1 and S(2)d(i) similar or equal to 0 was the only genotype most stable over all the environments studied.
