“…compared with tall lines, confirming previous results (Li et al 2006). However, Rht4 had higher adverse effect on TKW than Rht-B1b, though lower TKW was partly compensated by increased GN by single Rht4, this can only obtain similar yield of tall lines.…”

“…The gibberellin-insensitive gene Rht-B1b is one of the genes successfully introduced as a result of the Green Revolution and is widely distributed throughout the world [11]. The effect of the gibberellin-insensitive gene Rht-B1b on height can vary from about 10 to 25% in bread wheat and from about 25 to 35% in durum wheat compared to the wild-type allele Rht-B1a [6,[12][13][14][15][16][17]. Wheat varieties and lines with Rht-B1b compared to Rht-B1a show a higher grain yield compared to wild type [6,[15][16][17][18].…”

“…Rht-B1b increases the number of grains in the spike [17,18] and, as a result, the number of grains per square meter [15][16][17]. A number of studies have shown that Rht-B1b reduces the average mass of a single grain, although in a number of experiments the effect was not significant [12,13,[15][16][17]. Also, an increase in harvest index due to an increase in grain yield and a decrease in the total aboveground biomass is shown [15,17].…”

“…Однако при этом отсутствует кумулятивный эффект по снижению высоты растений от совместного присутствия двух генов. В то же время у пшеницы, по данным литературы (45,46), при совместном присутствии генов короткостебельности Rht-B1b и Rht-D1b или Rht-B1b/Rht-B1е/Rht-D1b и Rht-8 высота снижается значительно сильнее, чем под влиянием только одного из генов. Таким образом, если цель селекционного процесса будет заключаться в снижении высоты растения у тритикале, то сочетание двух генов короткостебельности (Ddw1 и Rht-B1b) вряд ли окажется более эффективным, чем интрогрессия одного из генов.…”
