The speciality rice variety such as Basmati and Jasmine maybe not be very suitable to plant under the Malaysian climate because the growth may be influenced by the changes in the environmental conditions causing the changes of its physical and chemical characters and results in low yield. Thus, an attempt was made through a hybridisation program among selected Malaysian rice varieties consist of MRQ50, MRQ74, MRQ76, MR219, Mahsuri Mutant, and Mahsuri Mutant 98 with Indian traditional rice, Basmati 370 with the main objectives, to compare the kernel elongation ratio of each cross and to determine the potential and suitable combination among crosses rice for further evaluation program. The results of the study indicated that among parental lines, Basmati 370 posed the highest elongation ratio 2.00 which revealed its speciality elongation trait of cooked rice. A comparison between crosses, rice cross between Basmati 370 and Mahsuri Mutant 98 showed the highest elongation ratio with the value 2.12 and the lowest elongation ratio of about 1.96 was found in rice cross between Basmati 370 and MR219. However, all hybridised rice poses a value of elongation ratio more than 1.6 which is considered good kernel elongation. The segregation pattern of all crosses also posed a ratio 3:1 whereas three is low elongation and one is high elongation which demonstrated the Mendelian inheritance of monogenic cross. The results obtained from this study could contribute to the existing literature on speciality rice production in Malaysia and beneficial for future rice quality improvement program. |
