Nine types of Mendelian chlorophyll deficiencies consisting of both unicoloured and variegated forms have been described and their inheritance discussed. Some of these like the “zebra-marked”, lutescent and certain variegated forms are recorded for the first time in rice. A beginning was made to study the inter-relationships of these types and all possible crosses were made with the albino, virescent yellow and the green and white striped as the parents and studied up to the F3 generation. It was found that while each of the three different types behaved as a simple recessive to the normal green, crosses between any two of them gave green F1 plants segregating in F2 into green and the parental types in the ratio of 9:3:4 showing the interaction of two factors. The crosses have further shown that three pairs of factors (Ww, Vv and Gw gw) are concerned in the.
