<p>In the middle of 1980s, rice self-sufficiency in Indonesia has been achieved, but the growth of rice production slowed down since the 1990s. Narrow genetic variability of released rice varieties contributed largely to the occurrence of leveling of potential rice yield over the past decades. To enlarge the genetic variability, an intersubspecies crossing of Koshihikari (japonica) and IR36 (indica) has been performed. Through this crossing, three high yielding and high yield quality promising lines of KI 37, KI 238, and KI 730 have been obtained. The objective of this study was to evaluate the superiorities of these lines through multi-location yield trials, pests, diseases, and grain qualities examinations. Examination methods used followed the release food crops variety procedure issued by the Indonesian Ministry of Agriculture. The result of examinations showed that the average yield of KI 730 was 7.47 t/ha, it was significantly higher than that of Ciherang (6,73 t/ha). KI 730 has a good grain quality, with translucent milled rice, a high percentage of milled rice (78.0%) and head rice (91.01%). The texture of its cooking rice was soft, sticky, with the amylose content of 20.41%. In addition, pests and diseases resistances of KI 730 were better than those of other lines tested. After evaluation by National Food Crops Release Variety Team, the KI 730 line was released as a national superior variety with the name of Tropiko. Tropiko should become an alternative variety to grow widely in order to increase national rice production and farmers income.</p>

In obtaining stable and high rice yields, the leading role belongs to the use of the best varieties, harmoniously combining productivity and technological indicators of grain and milled rice quality, adapted for cultivation in the main rice-growing regions. Therefore, the aim of our research is to evaluate new rice genotypes by a set of economically valuable traits that can replace obsolete varieties in the sowing area of the region and the country as a whole for industry efficiency. Experimental plots of competitive variety testing (CVT) were laid on the territory of the rice irrigation system of the experimental production department of the Federal Scientific Rice Centre, Belozerny, Krasnodar region for three years. The results are processed by analysis of variance and correlation analysis. All new varieties formed dense panicles of 10.0-11.9 pcs / cm with a sufficient number of fertile spikelets 139.7-165.9 pcs. on average, which is responsible for the high grain content of agrophytocenosis 44.1-58.2 thousand units/m2. Hence the high grain yield - 9.2-10.2 t / ha with a good combination of the main technological indicators - the mass of 1000 grains and head rice content. The closeness of the interconnections of the main economically valuable traits and the heat supply of the growing season is determined. Four varieties (except VNIIR 10284) show a neutral yield response to one of the main factors of external influence on the plant - the sum of effective temperatures above 15 ° C. According to the results of the test, for three years in CVT and in the environmental testing, the variety Romans was transferred to State variety testing, VNIIR 10279 is being prepared for transfer.
