Abstract

An investigation was undertaken during 2016-2022 to eliminate the off-flavour generating lipoxygenase-2 gene from Kunitz trypsin inhibitor-free (null KTi) soybean genotypes developed in the background of the popular variety JS 93-05 using molecular markers. Agronomically, MACSNRC 1898 has a semi-determinate plant type and semi-erect type growth habit with pointed ovate leaves. The plant grows to an average height of 65-69 cm, bears purple-coloured flowers in 35 days, and matures in 95 days after sowing. It gives an average yield of 2460 kg/ha. It bears three seeded pods with medium-sized yellow-coloured seeds having an elliptical shape with a
black-coloured hilum. MACSNRC 1898 is without KTi and Lox2 genes and with 92% genome of the recurrent parent genome content (RPGC). The genotype MACSNRC 1898 is useful in further breeding for the soybean varieties suitable for food use.
