在南印中部评价了含3～50％野生种质高粱群体的籽粒产量及九个有关性状。在 BC_0F_2至 BC_2的衍生系中,未出现籽粒产量的超亲分离。BC_3F_2或 BC_4F_2衍生系仅有1.5％的超亲分离,其平均籽粒产量较相应轮回亲本的高26％。10个与 CK60B 回交授粉的最高产的 BCF(—BC_4F_2衍生系,其产量比CK60B 平均高14％(达5％显著平准)。在产量提高的同时植株高度亦随之增高。来自 RS/R/A2725×帚枝高梁和 RS/R/A2725×轮生花序高梁的最高产品系,其产量较 RS/R/A2725高13.5％(平均),但株高相等。经选择 BC_2平均籽粒产量增加6～27％。在 BC中,群体平均产量,入选系平均产量和最高产量品系出现频率均为最高。
In central South India, grain yield and nine related traits were estimated for 3 to 50% of wild germplasm sorghum populations. In the BC_0F_2 to BC_2 derivative lines, no super-pro-segregation of grain yield occurred. The BC_3F_2 or BC_4F_2 derived lines had only 1.5% super-progeny separation, with an average grain yield of 26% higher than that of the corresponding reincarnated parent. Ten of the highest yielding BCF (-BC_4F2 derived lines backcrossed with CK60B (-BC_4F_2 derived line) had an average yield of 14% (significant flattening of 5%) over that of CK60B. The plant height also increased with increasing yield. The highest yield of R / A2725 × broom sorghum and RS / R / A2725 × inflorescence sorghum were 13.5% (average) higher than RS / R / A2725, but the plant height was the same.The average grain yield 6 ~ 27% .In BC, the average yield of the population, the average yield of the selected lines and the highest yield lines appeared the highest frequency.
